TS5013N69 Tamagawa Brushless Resolvers Synchros Rotary Encoders Incremental Encoders

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.
