Warner Dry, Single-face Clutches/Brakes

FEATURES

MODELS NAMES

Warner Clutches/Brakes are the most popular lineof Electro-magnetic clutches/brakes now used inlarge numbers in a wide variety of machines innumerous industries. Typical models of dry, single-face design, they have many importantperformance and structural features. Easily usedand installed, they can suit various applicationsinvolving operations ranging from simple startingand stopping to reversing, branch driving,positioning, including, speed variation, andintermittent tunning, in which they are especiallyserviceable when the running frequency is high.They come in end-to-end shaft, through shaft, andother standard types, plus a vriety of easily-usedunits including Electro-Pack clutch/brake units,Clutch-Coupler clutch units, and Electro-Sheaveclutches with V pulleys.

All models incorporate an "auto-gap" mechanism for automaticadjustment. Friction disk wear does not necessitate arduousgap adjustment.

1 No post-installation adjustment is required

A unique armature design enables frictional heat to bequickly released outside. This makes the unit serviceablein high-frequency on-off operations and under demandingservice conditions.

3 High heat release efficiency

Torque can be varied over a wide range by varying thecurrent. This makes possible such operations as slowstarting, braking, and slipping for tension control.

4 Broad freedom in torque control

Taper lock bushing is used to facilitate the assembly of theunit on the shaft and preclude loosening.

2 Easily assembled

Compact and lightweight, the unit takes up only aminimum of space, and can be mounted with ease.

5 Compact, lightweight, easily mounted

Made of choice materials and carefully designed, the unitstays very long in service while long maintaining its initialperformance characteristics, and consumes only aminimum of power.

6 Durable, and economical in power consumption

How to Select Warner Clutch/Brake Models (Simplified Model Selection Tables)

2

Clutch operating modes may bedivided into two types: The maximum torque is applied tothe system after it has been startedfully (for example, in a lathe, on whichthe work begins to be ground after itsrotation has reached the regularspeed).

The maximum torque is appliedwhen the clutch is actuated(forexample, in a conveyor system, inwhich case the load is already on thesystem when the clutch closes).By referring to Table I or II, it is easyto select the right clutch model for aparticular application from the motorcapacity and the clutch shaft speedinvolved.

If you are not sure which type ofclutch operating mode is expected,use Table II.If you have a brake in mind, use Table I.If the application you have in mindinvolves a high load GD2 or highactuating frequency or high turningspeed, ask the manufacturer for arecommendation.

A truly state of the art product whose performance and reliability sets it apart from other electromagnetic clutches/brakes. Through the use of our revolutionary "zero backlash auto gap technology" we are able to achieve unparalleled precision and operating life in an easily implemented dry-type single-plate driving electromagnetic clutches/brakes. Additionally, we have included innovations such as an asbestos-free facing on the friction plate, which meets and exceeds expectations with superior motion control performance. Our customer satisfaction thus far has been overwhelmingly positive.

Features1. Driven by a leaf spring with an integrated automatic gap adjustment Our original auto gap equipment experiences no backlash and does not require adjustment.*PATENT NO 1538370.

2. Rapid response and precise operationIdeal torque is immediately achieved by utilizing "a high efficiency magnetic circuit".

3. Excellent thermal radiation capabilityWe have increased the radiation capability by more than several 10% by including a radial fan with a large airflow rate flange.

4. Silent, vibration-free housingBy using a silent, composite plate housing, we were able to prevent unnecessary vibrations, allowing for silent operation.

5. Asbestos-Free FacingAbrasion resistance is increased 30% with a safe, asbestos-free facing.

6. Free mounting orientationYou are able to mount it vertically, horizontally or on an incline.

CIutch or Brake Selection GuideClutch operating modes may be divided into two types: The maximum torque is applied to the system after it has been started fuIIy (for example, in a lathe, on which the work begins to be ground after its rotation has reached the normal speed).The maximum torque is applied when the clutch is actuated (for example, in a conveyor system, in which case the load-is already on the system when the clutch closed).

By referring to Table I or II, it is easy to select the right clutch model for a paticular application from the motor capacity and the clutch shaft speed involved. If you are not sure which type of clutch operating mode is expected, use Table I. If you have a brake in mind, use Table I.

Selection Table I Maximum torque is applied after sysem has fully been started

Selection Table II Maximum torque is applied when sysem is started

The explanation of the Auto-gap function[Off time (Power is cut off)]This should cause the back side of armature to be attracted to Hub outer side. In this time, the air-gap between A-part and B-part is adjusted by Auto-gap function, also the air-gap between the armature and the frictional face of rotor is kept the same air-gap.

[On time]This should cause the armature to be attracted to the frictional face of the rotor. The torque of the electromagnetic clutch/brake will be supplied. In this time, the Hub outer will be attracted to the friction face. However, Hub outer is sustained at the same position by spring pin, AG-bush. and the air-gap between A-part and B-part is Zero, lightly contacted. After power is cut off, this should cause the armature to leave by spring, come back to the status Figure 1.

[On Auto-gap adjustment]As the frictional face is loosened by usage, beyond the specified Air-gap. The A-part and the B-part is strongly touched, hub outer is attracted to the friction face by the AG-volt. In this time, Hub outer is moved to the rotor side slightly within the frictional face loosened. In this result, Air-gap is kept with the specified gap automatically.

Operating Instructions

1. The frictin faces of the Clutch/brake are coated with a rust inhibitive, which need not be wiped off. Mount the components with out further processng, taking care not to contaminate the faces with oil or other foreign matters. They need not be wiped with thinner or trichloroethylene.

2. The gap between rotor and armature and between magnet and armature should be set initially in such a way as to meet the specification when the armature has been pressed throughly into the hub (refer to dimension "g" in the external dimension diagrams on Pages 8, 9 and 10). Since the gap Specification cannot be met if impacts are applied in the axial direction, do not hit the unit with a hammer or the like.2. Do not pull the armature off the hub or slide the armature

on the hub before they are completely mounted.

3. The dimensions concerning the key meet JIS B1301-1976 (newJIS).

3. Do not tighten the field detent. Leave it as loose as a common detent is.

4. The mounting screws should be fixed with an adhesive to keep them from loosening.

5. For installation accuracy, refer to Table 1.

6. For type JC clutches, use two ball bearings on the armature side (pulley side). Use hexagon socket head cap screws (JISB 1176-1974) as pulley and sprocket mounting bolts, and refer to Table 4 on page 11 for the tightening torque and the length of the bolts to be inserted into the hub.

Pre-installation instructions

1. The degree of fitting between the Clutch/brake and the shaft should be H7. h6 or H7. js6 as defined in JIS B0401, and they should be fixed with no play in the axial direction. Where shock loads are expected, the shaft diameter tolerance should be k6 or m6. Also, minimize the end play of the mounting shaft.

BrakeClutch

For SELC&B clutch/brake units, take note of the following in addition to the precautions on the previous page.1. The input and output shafts of type JEP are respectively designated as “INPUT” and “OUTPUT” on the nameplate. Be sure to connect the motor to the input shaft. For the dimensions of the input and output shafts, refer to the outline drawing.(Note) Output shaft only for type JEM.

2. The clutch/brake unit mounting surface should possess high rigidity, and the flatness must be 0.2 mm or less for the type 0.6 to 5 and 0.25 mm or less for the type 10 to 40 (0.2 mm or less for type JEM)

3. When installing pulleys and sprockets on the input and output shafts (output shaft only for type JEM), do not forcibly hit or hammer the shaft(s).

4. The clutch/brake unit is designed to allow use in all power transmission systems (direct coupling by the V-belt and pulleys, chain and sprockets, direct coupling, etc.).

(Notes)1. T.I.R. stands for total dial indicator reading. Accordingly, do not allow the deviation from concentricity to exceed one-half the values above.2. The deviation of the frictional face GAP indicates the angle error between the armature rotation center and shaft for type JC, the angle error between the shaft and shaft for type JCC, and the perpendicularity of the magnet attachment surface to the shaft for type JB.

(Notes)1. These graphs are based on 1,800r/min an 6000 hour bearing life expectancy.2. Use the appropriate speed and application coefficients for the turning speed and application you have in mind.3. The graphs are based on the assumption that no thrust load is involved.

Installation Example

5. Precautions on input hub (inner hub) installationUse hexagon socket head cap screws (JIS B1176-1974) as pulley and sprocket mounting bolts, and refer to Table 4 for the tightening torque and the length of the bolts to be inserted into the hub. The supplied electric discharge elements (varistors) are

absolutely necessary when the power unit of type DMP is used. When the controller of type EMP, CSM, CMPH, or TMP is used, never install the supplied varistors since electric discharge elements are incorporated.

After completing installation, apply power to the clutch/brake. This makes the armature stick to the frictional faces of the rotor and magnet. If it is not stuck completely, tap the outer periphery of the armature side in the rotor and magnet direction with a wooden hammer or driver handle. Then, cut off power. The armature will be separated from the friction plate and the gap will automatically be a proper value. Should the gap be narrow and readjustment is required, tap the outer periphery of the armature side in the direction opposite the above to extend the gap. Then, after sandwiching a shim of the approximately specified gap size between the frictional faces, press bushes (type 0.6 to 5: 3 locations, type 10 to 40: 6 locations) into the plane A of the inner hub shown below with a driver or the like and then perform the above work.

If there are no external vibrations or impacts in the axial direction, the installation posture is free in any direction (vertical, diagonal, etc.) as well as horizontal installation.However, do not allow the axial vibration level from the outside to exceed approximately 1.5G in the case of other than horizontal installation.If the vibration level exceeds that level, the specified frictional face gap may not be able to be maintained. Therefore, exercise great caution.

This series of clutches/brakes are designed to produce the rated torque from the initial stage. However, the specified torque (100% of the rated torque) may not be produced since the frictional faces do not conform sufficiently in the initial installation condition. In this case, perform light break-in operation.

CIutch or Brake Selection GuideStructureClutch operating modes may be divided into two types: The maximum torque is applied to the system after it has been started fuIIy (for example, in a lathe, on which the work begins to be ground after its rotation has reached the normal speed).The maximum torque is applied when the clutch is actuated (for example, in a conveyor system, in which case the load-is already on the system when the clutch closed).

By referring to Table I or II, it is easy to select the right clutch model for a paticular application from the motor capacity and the clutch shaft speed involved. If you are not sure which type of clutch operating mode is expected, use Table I. If you have a brake in mind, use Table I.

Selection Table I Maximum torque is applied after sysem has fully been started

Selection Table II Maximum torque is applied when sysem is started

Operating Instructions

The friction faces of the Clutch/brake are coated with a rust inhibitive, which need not be wiped off. Mount the components with out further processng, taking care not to contaminate the faces with oil or other foreign matters. They need not be wiped with thinner or trichloroethylene.

2. Do not tighten the field detent. Leave it as loose as a common detent is.

5. For installation accuracy, refer to Table 2.

6. For type NC-T clutches, use two bearings on the armature side (pulley side). The deviation of the armature outside diameter must be within 0.15 T.I.R. and the perpendicularity must be within 0.1 T.I.R. for type 0.3 to 2.5 or within 0.15 T.I.R. for type 5 to 20.

7. For NC-H type clutches, use hexagon socket head cap screws (JIS B1176-1974) to install pulley and sprockets.

- Wire Connection PrecautionsThe supplied electric discharge elements (varistors) are absolutely necessary when the power unit of type DMP is used. When the controller of type TMP, EMP, CSM, or CMPH is used, never install the supplied varistors since electric discharge elements are incorporated.

- Break-inThis series of clutches/brakes are designed to produce the rated torque from the initial stage. However, the specified torque (80% of the rated torque) may not be produced since the frictional faces do not conform sufficiently in the initial installation condition. In this case, perform light break-in operation.

- Installation PostureThe installation posture is free in any direction (vertical, diagonal, etc.) as well as horizontal installation.

3. The mounting screws should be fixed with an adhesive to keep them from loosening.

4. After adjusting the gap (dimension g) between the frictional faces with the attached shim, install the system. Refer to Table 1.

Pre-installation instructions

1. The degree of fitting between the Clutch/brake and the shaft should be H7. h6 or H7. js6 as defined in JIS B0401, and they should be fixed with no play in the axial direction. Where shock loads are expected, the shaft diameter tolerance should be k6 or m6. Also, minimize the end play of the mounting shaft.

A claw electromagnetic clutch which transmits torque by a direct linkage of the tooth plane. In addition to the characteristics usually found in a claw electromagnetic clutch (small, high torque and correct transmission), our unique tooth plane and tooth profile delivers incomparable transmission and disengagement characteristics. Additionally, with our unique tooth plane structure, we are able to create a "single position" clutch that mates only at one point on the circumference to enable correct, fixed position engagement and motion.

1. Large torque transmission with a small bodySmall and high torque are both possible due to the claw tooth mating.

4. Can connect even during rotationDepending on the usage condition, it is possible to engage even during (relative) rotation.

2. Torque transmission with no slippageCorrect operation which never slips during torque transmission.

5. Fixed position connection and synchronous operationThis single position clutch does not change its relative position after repeated connections and disconnections, so it is always connected at the proper position.

6. It can be used both wet and dryDepending on the location and the purpose, it is possible to operate this clutch both wet and dry.

3. Zero drag torqueDriving and load are completely separated when the power is cut off with no dragging.

CharacteristeicsSelection Guide1. Torque reduction rate

2. Operating Characeristics

1. About selection of torque capacityAs the rotation speed increases, the transmission torque lowers by the influences such as vibration of the machine (refer to the torque reduction rate on page 6). Therefore, when selecting torque capacity, reduction is compensated to obtain the required transmission torque based on the rotation speed in use and the torque reduction curve.The torque calculated here is to be the required torque capacity, and the final required torque capacity is determined by treating this with a safety factor (2 or higher).For example, in a case where the required transmission torque is 100Nm, the rotation speed is 300r/min, 60% of the torque is transmitted from the torque reduction rate table, that is, 100Nm x 100/60 = 167Nm. This multiplied by the safety factor 2 equals 334Nm, which is required for the capacity, that is, TO-40 type is required.

2. Engagement limit when relative rotationTooth clutches can be engaged in a state with relative rotation, however, in such a case, the engagement limit of a tooth clutch is restrained by the relative rotation speed, load inertia moment J, and load torque, and will be as shown in Figure 1.If your usage condition is in the area with broken lines in the figure (2 – 80 type and at relative rotation speed of 30r/min or more), please clearly specify your usage condition and consult with us beforehand. Static engagement is basically used for the 280 type and higher. And a single position type (SPO type) may be used for a case exceeding the engagement limit in the above figure, so please contact us.

3. About engagement limit of static engagement useAt the time of static engagement use, there is a case where tooth planes completely engage and a case where tooth planes incompletely engage. In a case of incomplete engagement, the tooth may slip without engagement when the accelerating torque is large on the drive side during start-up. In such a case, the motor must be started by specific methods such as kuza start, star-delta starting, start compensation, and reactor starting to restrain the accelerating torque.

4. Cautions for tooth plane torque of single position typeA single position type slips until it comes to the engagement point owing to its tooth plane structure, and while slipping, slipping generates tooth plane torque and dragging may occur on the load side. In such a case, it is necessary to prevent dragging by using the brake. The size of the tooth plane torque is 15% or less of the rated torque.

5. About restriction of load torque when clutch releaseBecause of the tooth characteristics, the tooth clutch cannot let out if a certain amount of load torque or more acts when releasing. The releasable torque is 20% or less of the rated torque.

Cautions for handling

(1) Make sure to fix securely in the axial direction in order to keep the attachment clearance g the value specified in the following table in a non-excitation state.

(2) Position the rotor (or the magnet body) and the armature with a collar of nonmagnetic materials (such as brass and stainless steel).

(3) The recommended tolerance of the attachment shaft is H7 · j6 or H7 · k6.

(4) Use a through shaft type of clutch whenever possible. If a split shaft type is to be used, please consult with us beforehand.

(5) Attach the field within the concentricity 0.10 T.I.R to the rotor attachment shaft.

(6) Use bolts to be attached to the field at a length not exceeding the maximum screwing depth of the field.

(7) Apply LOCKTITE, etc., to the attachment bolt of the spline adapter, in order to prevent loosening.

(8) Holes are made beforehand on the spline adapter for pin attachment. Finish them with a reamer to match the actual pin and always use pins together. H7, m6 is recommended for fitting of the pins.

(9) When using a dry type, it is recommended to apply grease thinly to the spline when mounting to smoothen the sliding surfaces of the spline adapter and the armature.

Installation precautions

(1) Purification of lubrication oilPay sufficient attention to purification of the lubrication oil. Attach a magnet plug, etc., on the bottom of the oil bath or the gear box storing the clutch/brake so that fine iron powder such as gear friction powder in the oil does not float. It is necessary to use a suction strainer (about 70～150 mesh) and a magnet plug and a filter together. If contamination of the lubrication oil becomes heavier during operation, or if the amount of sediment becomes larger, filter the oil or replace the oil. Always use the same brand of oil as the currently used oil for replacement.

(2) Temperature control of lubrication oilKeep the oil temperature at 60ϒC or less in a normal operating state. If the temperature increases, thoroughly examine the heat dissipation structure of the gear box or the oil tank, and attach a fan, etc., for forcible air cooling or an oil cooler, etc., to secure a sufficient cooling effect. And in the case of an oil bath, the temperature rise may be excessive owing to oil agitation and loss, etc., so special attention must be paid. If the size of the storing part of the clutch or the brake is small, provide an air vent.

(3) Replacement period of lubrication oil (reference)It is recommended to replace the lubrication oil at the replacement time shown in the table below. Also pay sufficient attention at inspection of the magnet plug and the filter used in order to purify the lubrication oil. Always use the same brand of oil for replacement.

(4) Limit of immersion in lubrication oilImmerse the clutch at 1/2 of its diameter or less in the lubrication oil. Immersing more than 1/2 of the diameter in the oil is unfavorable because of temperature rise.

When using in an oil bath

(10) When using a large type clutch, it is recommended to use a coupling for impact absorption to avoid impact as much as possible.

(11) TZ-160 type and STZ-160 type are for wet operation, therefore use them with the shaft core lubrication method.

Since the power supply part (terminal block, slip ring, brush, etc.) are exposed to exterior, and if hands, fingers, etc., come into contact, an electric shock may occur. Do not directly touch not only during operation but also during maintenance and inspection, and also design so as to install a protective cover, etc.

Design so as to install a cover to the power supply part of the TR type.

(Note)

(Note)

(Note)

1. The tubler brush can be used for both wet and dry operation by changing the brush module. Wet operation uses a braided bronze brush and dry operation uses a copper carbon brush.

2. During wet operation, if the peripheral speed of the spring is more than 12.7m/s or if the current usually flows on the spring, attach 2 brushes with a 90-degree angle between them and apply the current across both brushes.

3. Connect the plus side to the brush holder and connect the minus side to the separate brush sliding on the shaft attached to the clutch body Be careful not to connect the plus and minus terminals inversely..

4. When the clutch is used while submersed in oil, attach an idler brush in the forward direction of rotation without applying any additional current.5. If you use a clutch larger than our typeTR-280 for wet operation, use 4 AP45-1 type brushes, designating one as an idler, as is described in note 4.

1. The TO and SPO types are designed to be attached to a fixing adapter or a fixed part of the machine to maintain proper thermal dissipation. If there is insufficient space for ventilation or if the clutch is installed in a sealed box with direct sun exposure, the ambient temperature will increase. Please contact us for application advice.

2. If using the TR-280, 560, or 1120 types, attach the grounding brush to the shaft in order to protect the machine's shaft bearing.

DESIGN AND OPEFIATIONThe main components of the clutch/brake are the electromagnetic field (stationary part) containing the coil, the drive-part of the clutch (cylinder and input shaft) and the driven-part of the clutch (rotor and output shaft). The cylindrical space between the cylinder and the rotor is filled with dry magnetic particle. The cylinder is the nonsaturation type incorporating a nonmagnetic-flux barrier ring in the center of its rim. Consequently, its built-up characteristics is excellent.When the coil is excited with direct current from electrical source, the magnetic flux, as illustrated in the figure below, is established. The magnetized particle contained between the two rotating parts (rotor and cylinder) are solidified into a chainlike configuration, which bind tightly the two rotating

parts together. When the coil is deenergized, the magnetic flux instantaneously disappears, the solidified particles disperse, and the transmission of torque ceases immediately.Due to its structural design where the input and output shafts are of the split-shaft type or simple hollowed shaft type, installation of clutches and brakes is simplified. Moreover, since the stationary coil type, no sliping and brush are required. This facilitates inspection and maintenance of the equipment. In the case of the electromagnetic particle brake, the operating principle is identical with that of the clutch. However, the rotor, illustrated in the figure, is fixed to the bracket. When the coil is excited, braking is initiated.

Principle of heat pipe:The heat pipe has for the first time been utilized by NASA to cope with incandescence or space ships and heat dissIpation of communication devices, a new technology by which a large quantity of heat can be transported rapidly. Its distinguished features are wide spreading over various fields including electrical equipment field.

1. To use in the state of continuous slipTo use in the state of continuous slip with a constant torque and a constant rpm for tension control of dummy loads and start up windlng brake, the continuous slip power is calculated by the following formula. Here, it is possible to use the required brake torque by adjustirlg the rated torque in the range 3~100%.

Ps=0.103xTxn (W) T: Set torque of brake (Nm) n: rpm of brake shah (r/min)

Example (Conditions) Set torque of brake: T=35 (Nm) rpm of brake:n=65(r/min) Select the brake for the above state.

(1) Temporarily select the one having the rated torqur 50 Nm from the set torque 35Nm.

(2) Calculate the slip power. Ps=0.103×35×65≠234WThe type having the slip power larger than 234W is required.

(3) The type may be selected from the allowable slip power diagram:For the shaft type, the allowable slip power of POB-10 is 270W (234W<270W). Therefore, POB-10 may be used.

(4) The simple selection table below with the continuous slip power considered is based on rpm of 1000 r/min. Therefore, it is required to determine the feasibility of use at this rpm by an allowable slip power diagram.

2. To make tension controlTo make constant tension control with continuous slip applying a start up winding brake, calculation is made using the following formulae:

Principal data dimensions of application conditions necessary for exarmination: 1. Line speed: Maximum Vmax. Minimum Vmin (m/min) 2. Start up wlndlng dia: Maximum Dmax. Minimum Dmin (mm ø) 3. Set tension: Maximum Fmax, Minimum Fmin (N)

1) For start up winding brakeTo make start up winding control applying the electromagnet powder brake, following points should be examined:

Since the relative rpm exceeding 30 r/min of the maximum rpm (Nmax) is required for rpm of clutch input shaft No, No is temporarily set to 94 r/min (64 + 30) here.

Slip power of 317W or more and torque of 39Nm or more are required.

(8) The allowable slip power of POC-20 is 430W (317W<430W, 39 Nm<200 Nm) according to the Allowable Slip Power Diagram (see page 11), so POC-20 is available.

3) To use as torque limiterTo prevent overload of the motor or power engine as well as damage to the machine /product, the clutch is slipped by using the constant torque characteristic of an electromagnetic particle clutch when a torque exceeding a specified one is applied. Calculation is made using the following formula:

4) For simple ON-OFF use(1) Selecting clutch capacityWhen selecting a sutitable electromotor, choose one whose size is adequate for the torque value the clutch shaft must adjusted from 3 to 100% by controlling the exciting current.

As the cause of drag torque, the effect of clutch bearing loss, seal part friction loss, windage loss, or residual magnetism is suspected. Drag torque has no effect during continuous slip operation, but large drag torque exerts an adverse effect such as load drag during ON/OFF application. SINFONIA TECHNOLOGY CO., LTD. reduces drag torque to approximately 1% of the rated torque in consideration of the above.(Since the value of drag torque varies depending on the model, contact us separately.)

Before use(1) Be careful not to the lead wire damage, and be careful of the terminal block, as it is made of resin.

(2) The powder inserted sometimes settles in irregular distributed in the bottom of the unit places, by causing the shock of the transporting, making rotation difficult. In the cases, the unit may be turned upside down and the outside tapped slightly to correct it.

(3) Do not leave the unit in very humid places for a long time.

(4) Take care not to dmage the terminal stand and the electric blower.

At the time of installation(1) During installation, do not apply excessive force to the shaft especially.

(2) When the shaft type is directly connected with mating shaft, use flexible coupling surely. The concentricity and perpendicularity must be with the tolerance of the coupling used.

(3) When connecting the lead wire to the terminal block, use Amp terminal lug surely and fasten securely, and do not expose changed portions. Be careful not to let the lead wire come into contact with the rotating part.

(4) Be careful not to interfere with the ventilation window with the installing stand.

(5) For installation stand over size 5, install on both sides of the input and output. (Refer to the following for installation procedure)

(6) Provide space around the electric blower so as not to

block cooling air.

(7) When the electric blower stops or the ventilation of the electric blower is insufficient, the temperature of the brake will rise causing a danger of burning. Therefore, connect the temperature switch while operating.

(8) Take care that excessive shock is not given to the electric blower.

Cautions for handlingBefor the operation(1) After completing the installation, confirm whether control circuit is adequately functioned and the excited voltage is set within the specified value or not. In this time, do not rotate the clutch or brake and make the excited current to ON-OFF. And also dose the other portion of machine operate smoothly ?

(2) If there is not an error, operate in accordance with the following procedure. As the powder inserted sometimes settles in irregular distributed in the interior of clutch or brake, by causing of the shock the transporting, make the adapting operation to concentrate the powder into operating gap.

• Procedure of preparative operationA) At the condition of non excited unit, after rotating for 1 minute as high as possible (1000r/min.Max.), the excited current shall be set to 1/4_1/5 rated current, and ON and OFF operation that one cycle consists of 5 sec ON and 10 sec OFF shall be repeated 20 cycles during the rotation.

B) When clutch or brake is in stalled newly, or the equipment in stalled with clutch or brake is transported to the other places, after doing the preparative operation surely, the regular operation shall be done.

C) If the preparative operation is poor, the torque is lower or not stabilized, but if the preparative operation is proper, the powder (Magnetic powder) are evenly distributed into the unit, and so the torque is produced in propotion to the excited current.

Allowable overhand loadTo connect the clutch/brake unit through pulleys or sprockets, limit the overhang load within the allowable overhang of the input shaft or output shaft load (see Fig.1, Tabel 2 and 3).The overhang load practically acts are obtained by the following expression.

F= (N)D

Maintenance1. Surface temperatures in the normal operating condition are shown in the following table.

2. If the powder absorbts the humidity, the characteristic of unit is hindered. Be careful not to let the water or oil enter to the interior of the clutch/brake. Especially in the case of installing the unit adjacent to the gear box, as the oil will enter to the unit, mediating the shaft, the oil seal must be done perfecitly.

3. Confirm whether the bolts for the installation of clutch/brake, the mounting stand and coupling are loosened or not.

4. While the use, if the following malfunctions are detected, check the ball bearings and there is a trouble, change to the new ball bearings. Shown as the following table 6. • Rotation is heavy. • Torque varies at every rotation. • Noise is made from the bearing.

5. Torque may decrease when the clutch or brake is subject to long periods of use under severe working conditions. In such case, changing of the powder will restore the torque. Refer to the next procedures of changing powder.

If you need torque control or speed control with strict precision requirements, our hysteresis series fits the bill. To achieve such stable results, we produced a "pure electromagnetic linkage" clutch where the torque is transmitted and controlled using only electromagnetic force. Amongst non-contact clutches, we have achieved remarkable precision and constant torque. By design, this product is used exclusively in low-torque applications, but its extraordinary constant torque characteristics and controllability are simply unmatched by friction or claw type clutches.

1. Constant torque characteristics with excellent precisionStable, constant torque regardless of the slip revolution speed.

2. Correct, flexible proportion adjustmentThe torque is exactly proportional to the exciting current allowing high precision, flexible torque control.

3. High-speed rotationThe performance is not limited by the revolution speed because of the pure non-contact electromagnetic connection, easily enabling high-speed machinery.

4. Near-permanent life cycleSince there is neither mechanical contact nor abrasion, this part is essentially permanent.

5. Smooth linkage and correct repeatabilityDue to the electromagnetic connection, it experiences no shock. Furthermore, it exhibits high repetition and repeatability under high frequency operation.

6. Flexible mounting and operation orientationFeaturing simple mounting mechanics, it can be positioned longitudinally or laterally.

1. To use in the state of continuous slipTo use in a state of a constant torque, a constant rpm and continuous slip for tension control, etc., of a winding clutch and a start up winding brake using a hysteresis clutch/brake with high precision constant torque and accurate repetitive property, the continuous slip power is calculated by the following formula. Here, it is possible to use the required clutch/brake torque by adjusting the rated torque in the range of 3~100%.

Ps=0.103 x T x n (W) T: set torque of clutch or brake (Nm) n: rpm of brake shaft (r/min) In case of a clutch ni: (relative speed)=NoｰNs (r/min) No: clutch input speed Ns: clutch output speed

Example (Conditions) Set torque of brake: T=0.3 (Nm) rpm of brake:n=3600 (r/min) Select the brake for the above state.

(1) Temporarily select one having the rated torque 0.5 (Nm) from the set torque 0.3 (Nm).

(2) Calculate the slip power. Ps=0.103×0.3×3600≠111WThe type having the slip power of 111W or more.

(3) From the allowable slip power diagram, HB-5 cannot be used, so look at HB-10, the allowable slip power of HB-10 is 140W.(111W < 140W)Therefore, HB-10 can be used.

2. To make tension controlTo make constant tension control with a continuous slip using a winding clutch and a start up winding brake, calculation is made using the following formula. This section mentions only selection when a brake is used. When a clutch is used, refer to the catalogue of powder clutches/brakes.

Principal data dimensions of application conditions necessary for exarmination: 1. Line speed: Maximum Vmax. Minimum Vmin (m/min) 2. Start up wlndlng dia: Maximum Dmax. Minimum Dmin (mm ø) 3. Set tension: Maximum Fmax, Minimum Fmin (N)

1) For start up winding brakeTo make start up winding control applying the hysteresis brake, following points should be examined:

(Example)[Conditions]1.Line speed: Maximum Vmax=350m/min Minimum Vmin=250m/min2.Start up winding dia.: Maximum Dmax=ø550mm Minimum Dmin=ø100mm3.Set tension: F=5(N) constantSelect the brake for the above state.

Slip power of 28.7W or more and torque of 0.69Nm or more may be required.

(8) The allowable slip power of HB-10 is 38W (28.7W<38W, 0.69Nm<1Nm) according to the Allowable Slip Power Diagram (see page 6), so HB-10 is available.

Pre-installation precautionsDoes the shaft rotate smoothly without contact?

Installation precautions(1) Select couplings used for the input and output parts without backlash or play. It may cause torque pulsation.

(2) Apply adhesives like LOCTITE on set screws, mounting bolts to prevent them from loosening.

(3) Pay attention to the squareness and the concentricity of the mounting stand with the shaft core for the field and the rotor not to contact. And provide a shoulder to press the outer ring of the bearing.

(4) Assemble the mounting stand so as not to apply unreasonable force on the bearing.

(5) When using the input and output shafts for hanging a pulley, keep it within the allowable overhang load.

Post-installation precautions(1) If the clutch/brake is turned off at halt or low speed, remanent magnetism remains on the hysteretic ring and may generate remaining torque. When turning off, gradually reduce and cut off the electric current while keeping the relative rotation. Take about 2 to 5 seconds for a gradual decrease of the electric current as a guide.

(2) To use it at low speed, torque ripple may occur, so consult us before using at 100 r/min or less.

Allowable overhand loadAt the time of overhang drive using a pulley and the like, keep it within the allowable overhang load. The overhang load that actually acts can be obtained by the following formula.

Cautions for handling

F= (N)D

2Tf

Where, F : load (N) {kgf}T : transfer torque (Nm) {kgf}D: pitch diameter of a pulley, etc. (cm)f: load factor (2~4 in case of a belt)

1. This table is based on 2000r/min, and a bearing life 16000 hours as 　a standard.2. This table shows a case without thrust load.3. Multiply the coefficient in the following table according to the rotation 　speed or application.　When the multiplied value exceeds 10, use 10 as the value.

Safety precautionsBe sure to read this instruction before operation.

When using our products, please pay sufficient attention tosafety and perform the operation correctly by thoroughlyreading and understanding our catalogs and technicalinformation beforehand.Although we make every effort to secure quality control of our products, please carefully consider safety measures for machine operation in the case of failure of the machine.

DANGERIf you fail to follow the instructions, it may lead to death or serious injury of operators.

CAUTIONIf you fail to follow the instructions, it may lead toinjury of operators and physical loss or damage.

Sparks may be generated by slipping when braking. Never use the products in an atmosphere containing oil and combustible gases, etc., as there is a risk of ignition and explosion. In addition, be sure to cover the main body tightly when using in an environment with combustible materialssuch as cloth.

Due to the nature of our brake products, never request athird party other than SINFONIA or an agent designated by SINFONIA to repair, disassemble, or modify our brake products. In addition, should an accident or damage occur resulting from a repair defect by a third party, SINFONIA shall not be held responsible.

Bolts in an inappropriate tightening state may be destroyed by shear stress to result in a very dangerous state. Be sure to select and use the specified bolt materials by applying the defined torque, and then take measures to prevent them fromloosening using an adhesive agent or spring washers.

Never use the products in a place exposed to water drops, oil drops, or dust, a place with vibration or shock, or a place of high temperature and humidity, as it may result in damage ormalfunction of the products.

Make sure the application and purposes of use are appropriate before selection and design.

The SBR type is a brake specially designed for holdingand emergency stops. If it is constantly used for braking, the primary function will be lost after a short period of time resulting in release failure. If it is used as it is, the brake will burn out losing its braking force, which may cause an accidentsuch as the machine losing control.(Note: For braking, please select one among our non-excitation operating brakes, SBM, SBS, and ERS.)

Never use the products in an atmosphere with risk of ignition and explosion.

Check the peripheral environment before using the products.

Brakes of the non-excitation operating type are released when electricity flows to the coil.

Never repair, disassemble, or modify the products.

Bolts must be selected and used based on the specified strength taking complete measures to prevent loosening.

The SBR type cannot be used for braking.
