TS5208BN196 Tamagawa Brushless Resolvers FA-SOLVER Encoder

Brushless resolvers(FA-SOLVER®)

Brushless resolver can be used for high accurate feedback of position and speed sensing, and pole detection of motor. Through their features of resistance for harsh environment and other reasons, they are used with motors for machine tools and robots, in steelworks.

We collectively call these brushless resolvers as FA-SOLVER®, and renewed their lineup to cope with a new FA era.

FEATURES

Wide temperature range

Built-in type : -55 to +155℃
Shaft type : -30 to +100℃
Temperature compensation type (BRT): -10 to +80℃ (For details, please refer to each individual specification.)

Superior environment resistance

Vibration : 196 m/s²{20 G} at 10 Hz to 500 Hz, for 2 hours to each of three axes.
Shock : 981 m/s²{100 G} for 6 ms, 3 times to each of 6 axes, 18 times in total
Humidity : 90 % RH or above at 60 °C

High speed rotation

Built-in type : 10,000 min^-1(rpm)
Shaft type : 6,000 min^-1(rpm)
Allowable rotation speed of some types may differ from the above values. For details, please refer to each individual specification. In addition, types exceeding 10,000 min^-1(rpm) are also available.

High reliability

Resolver has the similar structure to electric motors but has high reliability because of no winding coil on its rotor. In particular, the built-in types are free from maintenance because ball bearings are not installed in them.

Long-distance transmission

Robustness against noise enables long-distance transmission

Capable of compact incorporation

The use of built-in types of Resolver minimizes housings of motors. Best suited for compact design

High speed rotation

Small & Light Weight

Rotary Encoders

Rotary measurement sensors with high accuracy and high resolution.
Encoders, at present, have been widely used for factory automations, measurements, office automation devices, medical equipment, aviation and universal fields. Various kinds of encoders (FA-CODER® as trade mark) from small to high absolution are available to meet all of the requirements.

Incremental Encoders

Incremental encoders generate pulses in a frequency proportional to the rotational speed.

Absolute Encoders

Absolute encoders output the absolute value of rotation angles.

Resolvers / Synchros

Brushless resolver and brushless synchro can be used for high accurate feedback of position, speed sensing, and pole detection of motor.
Through their features of resistance for harsh environment and other reasons, they are used with high speed motors for Hybrid/Electric vehicles and robots.

Resolvers

A resolver is an angle sensor that outputs rotational angles as two-phase AC voltages (analog signals). It features structurally high environmental resistance compared to other sensors due to its simple design comprised of only an iron core and a coil.

The principles of Synchro are similar to those of an electrical transformer. A shaft of the receiver rotates in unison with the rotation of a shaft of the transmitter. Using the above characteristics, Synchro is used for transmitting mechanical angle variation of transmitter over a long distance. (See fig. 1) Synchro is classified into 2 types. Torque Synchro and Control Synchro. Control Synchro detects the angle with receiving mechanical angle variation in the form of output voltage.

Absolute Encoders(Multi-Turn)

Absolute encoders output the absolute value of rotation angles.The encoders are used for position control of servo motors mounted on machine tools or robots.As shown in Figure 2, rotation slits are lined from the center on concentric circles. Slits indicates binary code strings of 2 pulses/rev from the center.Multi-turn absolute encoders memorize the rotation quantity data over one rotation.
