警告测量后应立即对绕组进行放电，以免触电。

环境温度每升高 20°C，绝缘电阻参考值即减小一半。

如果未达到参考电阻值，那说明绕组已经受潮，这时，必须在烘箱内烘干绕组。在 90°C 下烘 12-16 小时，然后在 105°C 下烘 6-8 小时。

如果安装了排水孔塞，必须拔除并关闭阀门，但在加热时必须是打开的。

被海水打湿的绕组必须重新进行绕线。


ZH

2.1.3 直接启动或三角形/星形接线启动

标准单速机器上的接线端子盒通常包含 6 个绕组端子以及至少 1 个接地端子。

将机器连接到电源之前必须根据当地规定进行接地。

铭牌上印有电压和接线参数。

直接启动 (DOL):可能需要采用 Y 或 D 绕组连接。

例如，660VY 和 380VD 分别表示 660V 电压的 Y 接线和 380V 的 D 接线。

星形/三角形接线启动 (Y/D):电源电压必须与三角形接线时电机的额定电压相等。

拆除接线板上的所有接线片。

对于双速电机、单相电机和特殊电机，电源接线必须按照接线盒内的说明进行。

表一

2.3 安装

2.3.1 散热

要达到标准性能，正常环境温度不应超过 40°C（海上标准为 +45°C 或 +50°C）。检查电机内空气流通是否充分。确保电机不受附近设备及表面热辐射或阳光直射的影响。有关更高环境温度及散热的信息请参阅《电机指南》或联系 ABB 营业部。

2.3.2 底座

所有底座准备工作由买方承担。

金属底座应该涂漆，以免生锈。

底座必须平整、坚固，足以抵抗短路产生的冲击力。还应固定它们的尺寸，以免因共振而产生振动。

在安装电机前，必须检查、清理底座表面上用于安装薄垫圈或底脚的多余漆和泥土。并且必须仔细检查是否有高度差和表面不平整的部位。如下图所示。

底座螺栓将底座螺栓固定在电机底脚上，并在螺栓和底脚之间放置一个 1 到 2 毫米的垫片。

用合适的工具直接对齐电机。用水泥填塞螺栓，检查对齐情况，然后钻孔固定销子。

排水孔经常检查打开的排水孔是否朝下。

在灰尘过多的环境中应关闭所有排水孔。

2.3.3 校正

校正准确与否是避免轴承故障、振动和轴外伸部位破裂的关键所在。

2.3.4 滑轨和皮带传动

如图 2 所示，将机器固定在滑轨上。水平放置滑轨，使其处于同一平面。

注意!任何电机底脚高度不能大于 μ 0.1 mm 公差范围。

ZH

检查机器轴是否与从动轴或主动轴平行。必须按照供应商的说明张紧所有皮带。

警告皮带过紧会损坏轴承并有可能造成电机轴破损。

因此，不要超过相关产品目录中规定的最大皮带张力（如径向轴承负载）。

2.4 连接标准电机的顶部装有接线盒，其两侧均可接入电缆。

有些电机顶部安装的接线盒可旋转 4 x 90 ，而有些的接线盒则安装在电机侧面。

产品目录对是否采用了这些方案作了说明。

必须密封未使用的电缆入口。

接线盒不仅装有主绕组引接线端子和接地端子，还能容纳热敏电阻、加热元件、双金属部件、开关或 PT100 电阻元件的接线端子。

警告加热元件或直接绕组加热元件的电源可在停机状态下接入接线端子盒。

辅助元件接线图见接线盒盖里或在机座的附加标签上。

警告单相电机的电容器能保留一定的电流，该电流可流过电机接线端子，即使电机已停止运转。

2.4.1 变速驱动连接

与正弦电源相比，变速驱动会在电机绕组上产生更高的电压应力，并有可能形成高频轴电压和轴承电流。因此，必须依照“VSD 应用范围 /绝缘材料选择规范” (3GZF500930-2) 标明电机绕组和轴承绝缘材料以及转换器输出元件上的滤波器的尺寸，该文件可向 ABB 索取。

在变速传动中，电机 (Pn > 30 kW) 必须用屏蔽好的对称电缆和能提供 360 的电缆密封管（即 EMC 电缆密封管）进行连接。详细情况请参阅 ABB 的使用手册《传动装置的接地和布线》(3AFY61201998)。

在应用变频器时，为了平衡电机机座和驱动机器之间的电势，电机机座必须采用外部接地。除非这两者都安装在相同的金属材料基准面上。

机座在 IEC280 以上的电机应采用 0.75 x 70 mm 的带状导线或至少两根 50 mm2 的圆导线。圆导线互相之间的距离至少为 150mm。

这种布置方法不属于电气安全范畴，其目的在于平衡电势。如果电机和变速箱安装在普通的钢基座上，则无需进行电势均衡。

为了符合 EMC 要求，请务必使用专用电缆和接线器。（请参阅变频器说明。）

用于变速驱动 (M2BA/M3BP) 的铸铁电机的最高允许转速不得超过下表所示的最高允许速度或铭牌上标明的速度。请联系 ABB 了解其它电机尺寸和型号的最高允许转速。轴承润滑应按后文中的说明进行。

450 3600 1800

表二

如果对本电机变速传动的适用性存在疑问，请联系 ABB。

警告不得超过润滑油和轴承的最高允许温度。

2.5 平衡电机转子可保持动态平衡。

依照标准，本机采用半键取得平衡，而且轴上贴有红色胶带,并注明“用半键平衡”。假如电机在运输过程中没有贴有任何注明 „Balanced with half key‰ 的胶带，电机仍认为是使用半键平衡。

为了避免振动，半联轴器或滑轮必须用带半键的加工后的键槽来进行校平衡。

用全键校平衡时，轴上贴有黄色胶带,并注明 „Balanced with full key‰。

进行无键平衡时，轴上贴有蓝色胶带,并注明 „Balanced without key‰。

表三

当取决于应用和负载情况，请参阅适用的产品目录。

立式电机的操作时间为以上数值的一半。

装有滚柱轴承的电机的油脂使用时间更短。为了能持续性工作，应考虑使用注油嘴。

4.1.4 配备油嘴的电机

润滑信息铭牌和润滑注意事项

如果机器装有润滑信息铭牌，请以规定数值为准。

在润滑信息铭牌上可了解润滑间隔时间与安装、环境温度和旋转速度之间的关系。

第一次使用或在注油后，可能会导致温度升高持续10-20小时。

ABB 的政策规定，可靠性是轴承润滑间隔时间的关键性问题。这就是我们应当遵守 L1 原则的原因所在。

A. 手动润滑

不停机润滑拔除放油口塞或打开隔离阀。确保润滑通道已打开。将适量的润滑油注入轴承。让电机运行 1 到 2 个小时，以便将所有多余的润滑油甩出轴承。关闭放油口塞或隔离阀。

停机润滑请在电机运转时上润滑油。如不行，也可在停机时进行润滑。在这种情况下，请使用半量润滑油，然后让电机全速运转数分钟。

电机停止后，将剩下的润滑油注入轴承室。运转 1 到 2 小时后，关闭放油口塞或隔离阀。

B. 自动润滑如采用自动润滑，则必须永久性地卸下放油口塞或打开隔离阀。

有些电机可能装有陈油收集器。请参阅设备特别说明。

本公司建议仅将本电机用于机电系统。请联系当地 ABB 营业部。

如果使用自动润滑系统，表中说明的每次润滑间隔的润滑油量应加倍。

如果对 2 极电机进行自动润滑，应遵守“润滑剂”一章中关于 2 极电机润滑剂建议的注意事项（即“注意！”项）。


ZH影响润滑间隔时间的因素立式电机的润滑间隔时间为上述数值的一半。

润滑间隔时间基于轴承操作温度 80°C（环境温度约为 +25°C）。注意！环境温度升高会相应提高轴承温度。轴承温度升高 15°C 时应将上述数值减半，而当轴承温度降低 15° C 时，则可能需要将上述数值增加一倍。

警告不得超过润滑油和轴承的最高操作温度。

4.1.6 润滑剂

警告不要混合不同类型的润滑剂。混合不相容的润滑剂可能会损坏轴承。

上润滑油时，务必使用具有以下特性的球轴承专用润滑油：含有锂复合基以及矿物油或 PAO 油的优质润滑油 40°C 下的基油粘度为 100-160 cST 稠度为 NLGI 级 1.5 - 3 * 温度范围保持在 -30°C - +120°C 之间。

*) 对垂直安装的电机，或在高温环境下，建议以较高值为准。

具有适当特性的润滑油各大润滑油制造商均有出售。

建议使用混合剂，但必须向润滑剂制造商索取书面保证，即在操作温度范围内混合剂不会损坏轴承或降低润滑剂的性能，这一点对 EP 混合剂来说尤其重要。

警告轴承温度较高，机座号为 280 到 450 时，建议不要采用含 EP 附加剂的润滑剂。

如果环境温度低于 -25°C 或高于 +55°C，或者轴承温度高于 110°C，请向 ABB 营业部咨询应采用何种润滑油。

可使用以下高温润滑油。

Esso Unirex N2, N3 或 S2（锂复合基） Mobil Mobilith SHC 100（锂复合基） Shell Albida EMS 2（锂复合基） SKF LGHQ 3（锂复合基） Klüber Klüberplex BEM 41-132（专用锂基） FAG Arcanol TEMP110（锂复合基）

1. General

NOTE!These instructions must be followed to ensure safe and proper installation, operation and maintenance of the motor. They should be brought to the attention of anyone who installs, operates or maintains this equipment. Ignoring the instruction may invalidate the warranty.

1.1 Declaration of Conformity

Declarations of Conformity with respect to the Low voltage Directive 73/23/EEC amended by Directive 93/68 EEC are issued separately with individual machines. The Declaration of Conformity also satisfies the requirements of a Declaration of Incorporation with respect to the Machinery Directive 98/37/EEC, Art 4.2Annex II, sub B

1.2 Validity

The instructions are valid for the following ABB electrical machine types, in both motor and generator operation.

series MT*, MBT*, MXMA,series M2A*/M3A*, M2B*/M3B*, M2C*/M3C*, M2F*/M3F*, M2L*/M3L*, M2M*/M3M*, M2Q*, M2R*/M3R*, M2V*/M3V*

in frame sizes 56 - 450.

There is a separate manual for e.g. Ex motors ÂLow voltage motors for hazardous areas: Installation, operation and maintenance ManualÊ (Low Voltage Motors/Manual for Ex-motors).

Additional information is required for some machine types due to special application and/or design considerations. Additional information is available for the following motors:

roller table motors water-cooled motors open drip proof motors smoke venting motors brake motors permanent magnet motors

2. Installation

2.1 Putting into service (starting)

2.1.1 Reception check

Immediately upon receipt check the machine for external damage and if found, inform the forwarding agent without delay.

Check all rating plate data, especially voltage and winding connection (star or delta). The type of bearing is specified on the rating plate of all motors except the smallest frame sizes.

Remove transport locking if employed.Turn shaft by hand to check free rotation.

Do not exceed permissible loading values of bearings stated in the product catalogue.

Motors equipped with roller bearings: Running the motor with no radial force applied to the shaft may damage the roller bearing.

Motors equipped with angular contact bearing: Running the motor with no axial force applied in the right direction to the shaft may damage the angular contact bearing.

Motors equipped with regreasing nipples: When starting the motor for the first time, or after long storage of the motor, apply the specified quantity of grease until grease is forced out of the grease outlet.

For details see section „Manual lubrication" on page 9.

2.1.2 Insulation resistance check

Measure insulation resistance before commissioning and when winding dampness is suspected.

Resistance, measured at 25°C, shall exceed the reference value, i.e. 10 M ohm (measured with 500 V dc Megger)

WARNINGWindings should be discharged immediately after measurement to avoid risk of electric shock.

Insulation resistance reference value is halved for each 20°C rise in ambient temperature.

If the reference resistance value is not attained, the winding is too damp and must be oven dried. Oven temperature should be 90°C for 12-16 hours followed by 105°C for 6-8 hours.

Drain hole plugs, if fitted, must be removed and closing valve, if fitted, must be opened during heating.

Windings drenched in seawater normally need to be rewound.


EN

2.1.3 Direct-on-line or star/delta starting

The terminal box on standard single speed machines normally contains 6 winding terminals and at least one earth terminal.

Earthing must be carried out according to local regulations before the machine is connected to the supply voltage.

The voltage and connection are stamped on the rating plate.

Direct-on-line starting (DOL):Y or D winding connections may be used.

e.g. 660 VY, 380 VD indicates Y-connection for 660 V and D-connection for 380 V.

Star/Delta starting (Y/D):The supply voltage must be equal to the rated voltage of the machine in D-connection.

Remove all connection links from the terminal block.

For two-speed, single phase and special machines, supply connection must follow the instructions inside the terminal box.

If direct-on-line starting lasts for more than 10 seconds or Y/D starting more than 30 seconds, consult ABB Sales Office or see the publication ÂThe Motor Guide' (also available on the internet on www.abb.com/motors&generators).

2.1.4 Terminals and direction of rotation

Direction of rotation is clockwise when viewing the shaft face at the machine drive end, when the line phase sequence L1, L2, L3 is connected to the terminals as shown in the figure 1.

To alter the direction of rotation, interchange the connection of any two line cables.

If the machine has a uni-directional fan, ensure that the direction of rotation is according to the arrow marked on the machine.

2.2 Handling

2.2.1 Storage

The machine should always be stored indoors, in dry, vibration free and dust free conditions.

Unprotected machined surfaces (shaft-ends and flanges) should be protected with anti-corrosive treatment.

It is recommended that shafts be rotated periodically by hand to prevent grease migration.

Anti condensation heaters, if fitted, should preferably be energised.

The characteristics of electrolytic capacitors, if fitted to single-phase motors, will require „reforming‰ following periods of storage exceeding 1-2 years.

Contact ABB Sales Office for details.

2.2.2 Transportation

Machines fitted with cylindrical-roller and/or angular contact bearings must be fitted with locking devices during transport.

2.2.3 Lifting

Lift the motor using the lifting lugs only, if not otherwise stated in the separate lifting instruction.

The center of gravity of motors with the same frame may vary due to different outputs, mounting arrangements and auxiliary equipment.

Check that eyebolts or the lifting lugs integrated with the motor frame are undamaged before lifting. Damaged lifting lugs must not be used.

Lifting eyebolts must be tightened before lifting. If needed the position of the eyebolt must be adjusted with suitable washers.

Ensure that proper lifting equipment is used and that the sizes of the hooks are suitable for the lifting lugs.

Care must be taken not to damage auxiliary equipment and cables attached to the motor.


EN

Before mounting the motor, the foundation surface for the shims or for the feet must be clean from thick paint, paint drops and dirt. Then it should be checked in order to discover any height differences between the individual foot locations. Also, the smoothness within each footprint area has to be checked. The requirements are noted in the figure below.

Foundation studsBolt the foundation studs to the feet of the motor and place a 1-to-2 mm shim between the stud and the feet.

Align the motor directly using appropriate means. Grout the studs with concrete, check alignment and drill holes for locating pins.

Drain holesAlways check that open drain holes face downward.

In extremely dusty environments, all drain holes should be closed.

2.3.3 Alignment

Correct alignment is essential to avoid bearing failures, vibrations and possible fractured shaft extensions.

2.3.4 Slide rails and belt drives

Fasten the machine to the slide rails as shown in figure 2. Place the slide rails horizontally on the same level. Check that the machine shaft is parallel with driven, or driving,

shaft. Any belt must be tensioned according to the supplier 's

instructions.

WARNINGExcessive belt tension will damage bearings and can cause shaft breakage.

Do not exceed the maximum belt forces (i.e. radial bearing loading) stated in the relevant product catalogues.

Note! Height difference shall n o t ex c e e d μ 0 , 1 m m referred to any other motor foot location

2.3 Installation

2.3.1 Cooling

Normal ambient temperatures should not exceed 40°C (marine standard +45 or +50°C) if standard performance is to be achieved. Check that the motor has sufficient airflow. Ensure that no nearby equipment, surfaces or direct sunshine, radiate additional heat to the motor. For more information about higher ambient temperatures and cooling, see „the Motor Guide‰ or contact ABB Sales Office.

2.3.2 Foundation

The purchaser bears full responsibility for preparation of the foundation.

Metal foundations should be painted to avoid corrosion.

Foundations must be even, and sufficiently rigid to withstand possible short circuit forces. They shall be dimensioned as to avoid the occurrence of vibration due to resonance.


EN

2.4 Connection

Normal machine design has the terminal box on top with cable entry possible from both sides.

Some machines are available with top mounted terminal boxes rotatable 4 x 90 , and some with side mounted terminal boxes.

Availability of these solutions is described in the product catalogues.

Unused cable entries must be closed.

As well as main winding and earthing terminals, the terminal box can also contain connections for thermistors, standstill heating elements, bimetallic, switches, or PT 100 resistance elements.

WARNINGVoltage may be connected at standstill inside the terminal box for heating elements or direct winding heating.

Connection diagrams for auxiliary elements are found inside the terminal box cover or in additional labels on the frame of the machine.

WARNINGThe capacitor in single-phase motors can retain a charge that appears across the motor terminals, even when the motor has reached standstill.

2.4.1 Connection for variable speed drive

Variable speed drives cause higher voltage stresses than the sinusoidal supply on the winding of the motor and may cause high frequency shaft voltages and bearing currents. Therefore the winding and the bearing insulation of the motor as well as the filter at the converter output must be dimensioned according to "Selection rules for VSD applications/Insulation" (3GZF500930-2), available on request from ABB.

In variable speed drives the motor (Pn > 30 kW) must be cabled by using shielded symmetrical cables and cable glands providing 360 bonding (also called EMC glands). More information can be found in ABBÊs manual „Grounding and cabling of the drive system‰ (3AFY61201998).

In frequency converter applications motor frame external earthing must be used for equalising the potential between the motor frame and the driven machine, unless the two machines are mounted on the same metallic base.

For motor frame sizes above IEC 280, use 0.75 x 70 mm flat conductor or at least two 50 mm2 round conductors. The distance of the round conductors must be at least 150 mm from each other.

This arrangement has no electrical safety function; the purpose is to equalise the potentials. When the motor and the gearbox are mounted on a common steel fundament, no potential equalisation is required.

To comply with EMC-requirements, use only cables and connectors approved for this purpose. (See instruction for frequency converters.)

The highest permissible rotational speed of a cast iron motor used in variable speed drive (M2BA/M3BP) must not exceed maximum permissible speeds as stated in the table 2 below or the speed stamped on the rating plate. For information on the highest permissible rotational speed for other motor sizes and types, please contact ABB. Bearing lubrication should follow the directions mentioned later.

450 3600 1800

Table 2

If there is uncertainty concerning the suitability of the motor for the variable speed drive, please contact ABB.

WARNINGThe maximum operating temperature of the grease and bearings must not be exceeded.

2.5 Balancing

The rotor of the machine is dynamically balanced.

As standard, balancing has been carried out using half key, and the shaft is marked with a RED tape, with the text „Balanced with half key‰. In case of motors delivered without any tape defining the type of balancing, these motors are also balanced with half key.

To avoid vibration the coupling-half or pulley must be balanced with half key after the keyway has been machined.

In the event of balancing with full key the shaft is marked with a YELLOW tape, with the text „Balanced with full key‰.

In case balancing without key, the shaft is marked with a BLUE tape, with the text „Balanced without key".

3. Operating

3.1 Use

3.1.1 Operating conditions

The machines are intended for use in industrial drive applications.Normal ambient temperature limits are -20° to +40°C.Maximum altitude 1000 m above sea level.

3.2 Safety considerations

The machine is intended for installation and use by qualified personnel, familiar with relevant safety requirements.

Safety equipment necessary for the prevention of accidents at the installation and operating site must be provided in accordance with the local regulations.

WARNINGSmall motors with supply current directly switched by thermally sensitive switches can start automatically.

3.2.1 Points to observe

1. Do not use the machine to step on.2. The temperature of the outer casing of the machine may be hot to

the touch during normal operation.3. Some special machine applications require special instructions (e.g.

using frequency converter supplies).4. Lifting lugs must only be used for lifting the motor. They must not be used to lift the motor when it is attached to other equipment.

3.3 Assembly and dismantling

3.3.1 General

Dismantling and assembly of machines must be carried out by qualified personnel using only suitable tools and working methods. All repairs must be carried out according to the standard IEC-60079-19.

3.3.2 Bearings

Special care should be taken with the bearings.These must be removed using pullers and fitted by heating or using special tools for the purpose.

How to replace bearings is described in detail in a separate instruction leaflet available from ABB Sales Office.

3.3.3 Fitting coupling halves and pulleys

Coupling halves and pulleys must be fitted using suitable equipment and tools that do not damage the bearings.

Never fit a coupling half or pulley by hammering into place or remove it using a lever pressed against the body of the machine.

Mounting accuracy of coupling half:

check that the clearance b is less than 0.05 mm and that the difference a1 to a2 is also less than 0.05 mm. See figure 3.


EN

4. Maintenance

4.1 Maintenance and lubrication

4.1.1 General inspection

Inspect the machine at regular intervals. Keep the machine clean and ensure free ventilation airflow. Check the condition of shaft seals (e.g. V-ring) and replace if

necessary. Check the condition of connections and mounting and assembly

bolts. Check the bearing condition by listening for unusual noise, vibration

measurement, bearing temperature, inspection of spent grease or SPM bearing monitoring.

* When changes of condition occur, dismantle the machine, check the parts and replace if necessary.

4.1.2 Lubrication

WARNING Beware of all rotating parts!

WARNINGGrease can cause skin irritation and eye inflammation. Follow all safety precautions specified by the manufacturer.

4.1.3 Machines with permanently greased bearings

Bearings are usually permanently greased bearings of either Z or 2Z types.

Bearing types are specified in the respective product catalogues and on the rating plate of all our motors except smaller frame sizes.

As a guide, adequate lubrication for sizes up to 200 can be achieved for the following duration, according to L1 (i.e. that 99 % of the motors are sure to make the interval time) at ambient temperature of 25°C. For duties with ambient temperatures higher than 25°C, see the respective product catalogue.

Table 3

Depending on application and load conditions, seeapplicable product catalogue.

Hours of operation for vertical motors are half of the above values.

Motors with roller bearings have considerably shorter grease life. For continuous operation regreasing nipples should be considered.

4.1.4 Motors with regreasing nipples

Lubrication information plate and general lubrication advice

If the machine is fitted with a lubrication information plate, follow the given values.

On the lubrication information plate, regreasing intervals with regard to mounting, ambient temperature and speed of rotation can be defined.

During the first start or after a bearing lubrication it may appear a temporary temperature rise, appr. 10-20 hours. ABB policy is to have reliability as a vital issue in bearing lubrication intervals. That is why we follow the L1-principle.

A. Manual lubrication

Regreasing while motor is running Remove grease outlet plug or open closing valve if fitted. Be sure that the lubrication channel is open Press the specified amount of grease into the bearing. Let the motor run 1-2 hours to ensure that all excess grease is forced

out of the bearing. Close the grease outlet plug or closing valve if fitted.

Regreasing while motor is at a standstillRegrease motors while running. If this is not possible, lubrication can be carried out while the machine is at a standstill. In this case, use only half the quantity of grease, then run the motor

for a few minutes at full speed. When the motor has stopped, press the rest of the specified amount

of grease into the bearing. After 1-2 running hours close the grease outlet plug or closing valve

if fitted.

B. Automatic lubricationThe grease outlet plug must be removed permanently with automatic lubrication or open closing valve if fitted.

Some motors may be equipped with a collector for old grease. Follow the special instructions given for the equipment.

We recommend only the use of electromechanical systems. Contact your local ABB Sales Office.

The amount of grease per each lubrication interval stated in the tables 4-5 should be doubled if an automatic regreasing system is used.

If 2-pole motors are being automatically regreased, the note (NOTE!) concerning lubricant recommendations given for 2-pole motors in the chapter Lubricants shall be followed.


EN

Factors influencing the lubrication intervalsLubrication intervals for vertical machines are half of the above values.

The lubrication intervals are based on bearing operating temperature 80 C (ambient temperature of about + 25 ). Note! An increase in the ambient temperature raises the temperature of the bearings correspondingly. The values should be halved for 15 C increase in bearing temperature and may be doubled for 15 C decrease in bearing temperature.

WARNINGThe maximum operating temperature of the grease and bearings must not be exceeded.

4.1.6 Lubricants

WARNINGDo not mix different types of grease. Incompatible lubricants may cause bearing damage.

When regreasing, use only special ball bearing grease with the following properties: good quality grease with lithium complex soap and with mineral- or

PAO-oil base oil viscosity 100-160 cST at 40°C consistency NLGI grade 1.5 - 3 *) temperature range -30°C - +120°C, continuously.

*) For vertical mounted motors or in hot conditions a stiffer end of scale is recommended.

Grease with the correct properties is available from all major lubricant manufacturers.

Admixtures are recommended, but a written guarantee must be obtained from the lubricant manufacturer especially concerning EP admixtures, that admixtures do not damage bearings or the properties of lubricants at the operating temperature range.

WARNINGLubricants containing EP admixtures are not recommended in high bearing temperatures in frame sizes 280 to 450.

If the ambient temperature is below -25°C or above +55°C, or bearing temperature is above 110°C, consult ABB Sales Office regarding suitable grease.

The following high performance grease can be used

Esso Unirex N2, N3 or S2 (lithium complex base) Mobil Mobilith SHC 100 (lithium complex base) Shell Albida EMS 2 (lithium complex base) SKF LGHQ 3 (lithium complex base) Klüber Klüberplex BEM 41-132 (special lithium base) FAG Arcanol TEMP110 (lithium complex base)

NOTE! Always use high speed grease for high speed machines and some other models, e.g. M2 BA 355 and 400 2-pole machines, where the speed factor is higher than 400 000 (calculated as Dm x n where Dm = average bearing diameter, mm; n = rotational speed, r/min).

The following grease can be used: FAG L69 (polyurea base) Klüber Klüber quiet BH 72-102 (polyurea base) Lubcon Turmogrease PU703 (polyurea base)

If other lubricants are used, check with the manufacturer that the qualities correspond to those of the above mentioned lubricants, or if the compatibility of the lubricant is uncertain, contact your local ABB Sales Office.

WARNINGEspecially in high rotational speed (the speed factor > 400000) over greasing may cause damage.

4.1.7 Frequency converter drives

Higher speed operation, e.g. in frequency converter applications, or lower speed with heavy load will require shorter lubrication intervals. Consult your local ABB Sales Office in such cases.

Typically a doubling of speed will require a reduction of lubrication intervals to approx. 40 % of values tabulated above.

WARNINGThe constructional maximum speed of the motor must not be exceeded (see table 2).

Suitability of bearings for high speed operation must be checked.

4.1.8 Spare parts

When ordering spare parts, the full type designation and product code, as stated on the rating plate, must be specified.

If the machine is stamped with a serial manufacturing number, this should also be given.

For more information, please visit our web site www.abb.com/partsonline.

4.1.9 Rewinding

Rewinding should always be carried out by qualified repair shops.

Smoke venting and other special motors should not be rewound without first contacting ABB.

5. Environmental requirements

5.1 Noise levels

Most of our motors have a sound pressure level not exceeding 82 dB(A) refer to 50 Hz sinusoidal supply conditions, tolerance μ 3 dB(A).

Values for specific machines can be found in the relevant product catalogues.

For sound pressure levels for 60 Hz sinusoidal supply and with non-sinusoidal supplies, contact ABB Sales Office.

Sound pressure levels for all machines having separate cooling systems and for series M2F*/M3F*, M2L*/M3L*, M2R*/M3R*, M2BJ/M3BJ and M2LJ/M3LJ are indicated in separate Manuals.

Motor troubleshooting chartYour motor service and any troubleshooting must be handled by qualified persons with proper tools and equipment.

TROUBLE CAUSE WHAT TO DOMotor fails to start Blown fuses Replace fuses with proper type and rating.

Overload trips Check and reset overload in starter.

Improper power supply Check to see that power supplied agrees with motor rating plate and load factor.

Improper line connections Check connections with diagram supplied with motor.

Open circuit in winding or control switch Indicated by humming sound when switch is closed. Check for loose wiring connections. Also, ensure that all control contacts are closed.

Mechanical failure Check to see if motor and drive turn freely. Check bearings and lubrication.

Short circuited stator Poor stator coil connection

Indicated by blown fuses. Motor must be rewound. Remove end bells, locate with test lamp.

Rotor defective Look for broken bars or end rings.

Motor may be overloaded Reduce load.

Motor stalls One phase may be open Check lines for open phase.

Wrong application Change type or size. Consult manufacturer.

Overload Reduce load.

Low voltage Ensure the rating plate voltage is maintained. Check connection.

Open circuit Fuses blown, check overload relay, stator and push buttons.

Motor runs and then dies down

Power failure Check for loose connections to line, to fuses and to control.

Motor does not come up to speed

Not applied properly Consult supplier for proper type.

Voltage too low at motor terminals because of line drop

Use higher voltage or transformer terminals or reduce load. Check connections. Check conductors for proper size.

Starting load too high Check load motor is supposed to carry at start.

Broken rotor bars or loose rotor Look for cracks near the rings. A new rotor may be required, as repairs are usually temporary.

Open primary circuit Locate fault with testing device and repair.

Motor takes too long to accelerate and/or draws high amp

Excessive load Reduce load.

Low voltage during start Check for high resistance. Adequate wire size.

Defective squirrel cage rotor Replace with new rotor.

Applied voltage too low Get power company to increase power tap.

Wrong rotation Wrong sequence of phases Reverse connections at motor or at switchboard.


EN

TROUBLE CAUSE WHAT TO DOMotor overheats while running underloaded

Overload Reduce load.

Frame or bracket vents may be clogged with dirt and prevent proper ventilation of motor

Open vent holes and check for a continuous stream of air from the motor.

Motor may have one phase open Check to make sure that all leads are well connected.

Grounded coil Locate and repair.

Unbalanced terminal voltage Check for faulty leads, connections and transformers.

Motor vibrates Motor misaligned Realign.

Weak support Strengthen base.

Coupling out of balance Balance coupling.

Bearings not in line Line up properly.

Balancing weights shifted Rebalance motor.

Contradiction between balancing of rotor and coupling (half key - full key)

Rebalance coupling or motor.

Polyphase motor running single phase Check for open circuit.

Excessive end play Adjust bearing or add shim.

Scraping noise Fan rubbing fan cover Remove interference.

Fan striking insulation Clear fan.

Motor loose on bedplate Tighten holding bolts.

Noisy operation Airgap not uniform Check and correct bracket fits or bearing.

Rotor unbalance Rebalance.

Hot bearings ball Bent or sprung shaft Straighten or replace shaft.

Excessive belt pull Decrease belt tension.

Pulleys too far away Move pulley closer to motor bearing.

Pulley diameter too small Use larger pulleys.

Misalignment Correct by realignment of drive.

Insufficient grease Maintain proper quality of grease in bearing.

Deterioration of grease or lubricant contaminated

Remove old grease, wash bearings thoroughly in kerosene and replace with new grease.

Excess lubricant Reduce quantity of grease, bearing should not be more than 1/2 filled.

Overloaded bearing Check alignment, side and end thrust.

Broken ball or rough races Replace bearing, first clean housing thoroughly.
