TS2028, and TS2054)

• Usable in Demanding Environments

Vibration : 196m/s2 20G at 10~500Hz

Shock : 981m/s2 100G for 11ms

Humidity : 90% Rh Min. at 60°C

• High reliability and long life owing to brushlessness

• Operating speed up to :

100~500s-1 6000~30000min-1 / (Built-in type)

100s-1 6000min-1 / (Shaft type)

• Free from electrical and mechanical noise

FEATURES

Smartsyn, and brushless resolvers, are to offer you highlyenhanced reliability which has been enabled by excludinghuman-dependent works in the major production /inspection procedures from parts processing, assembling toshipping.

We’d like to offer the resolvers for such applications asfollows. • Commutation of brushless motors• Feedback sensor of servo systems• Robots• Machine tools• Aerospace servo systems• Others where harsh environmental condition is involved

Smartsyn is a name of our brushless resolvers of a newtype. They have their inherent characteristics as a resolver :maintenance-free brushless design, immunity to noise,vibration, shock, and high temperature.And now they have more to offer : homogeneity in the ever-variable parameters like accuracy, transformation ratio,phase shift, etc., which has been realized by highlyautomated production. Now this new quality can be takenfor granted.

MOUNTING REQUIREMENTS

PRINCIPLE

The following mounting requirements should be kept to

satisfy the specifications.

• Shaft Run-out

A motor shaft on which Rotor is mounted should have

a run-out less than 0.050mm (TIR).

• Concentricity

Centers of resolver and motor shaft should be

aligned within 0.050mm (TIR).

• Perpendicularity

Resolver case should be perpendicular to the

motor shaft within 0.050mm (TIR).

• Axial Alignment

For built-in types, Stator and Rotor should be axially

aligned within the tolerance of MTG.DIM.

Resolver is a rotary transformer, which outputs AC voltage

in accordance with angular position of the shaft.There are

two types of resolvers, BRX and BRT, having different

types of winding.

BRX resolver is excited by AC voltage to the rotor winding,

and outputs from the stator windings sine and cosine

voltages proportion to the rotation angle θ.

BRT resolver is excited by sine and cosine voltages to the

stator windings, and outputs from the rotor winding a sine

voltage phase-shifted in proportion to θ.

The difference is illustrated as follows.

Excitation : ER1-R2=Esin ωt

Output : ES1-S3=K ER1-R2 cos θ

ES2-S4=K ER1-R2 sin θ (Normal Type)

ES2-S4= –K ER1-R2 sin θ (Reverse Type)

K : Transformation Ratio

Excitation : ES1-S3=Esin ωt

ES2-S4=E cos ωt

Output : ER1-R2=K ES1-S3 cos θ –K ES2-S4 sin θ

=KE sin (ωt-θ) (Normal Type)

ER1-R2=K ES1-S3 cos θ + K ES2-S4 sin θ

=KE sin (ωt + θ) (Reverse Type)

APPLICATION NOTES

The supply voltage is a rated value, and a resolver can

accept a voltage from 3V to approx. 1.2 times as high as

the rating. However, the supply frequency should only

be altered within ±5% lest it should affect the accuracy.

Electrical parameters largely vary as the frequency

varies as shown on the right.

When a noise source is in vicinity, or when signal

transfer distance is long, twisted/shielded pair cables

should be used. When a noise still exists on the signals,

they should be received by a differential amplifier.

In BRX resolver, the two output voltages should be

connected to the same amount of loads each other, or

the voltages will get disproportionate, thus affect the

accuracy.

When an intense magnetic field surrounds a resolver, it

may not work properly with its magnetic flux affected.

When a resolver is used in a high humidity as close to

100% Rh for a long time, waterproof structure should be

considered lest its insulation materials should

deteriorate.

All resolvers in the catalog are 1× ( 2 poles) resolvers.

For winding modifications to other speeds, please

consult us.

after the warranty period, Tamagawa Seiki offers repair service, with charge, in

order to maintain the quality of the product. The MTBF (mean time between
