Resolver Synchro Tamagawa

resolver Synchro

The Synchro resolver were among the first angular transducers produced ​​by Tamagawa in 1938. Extremely tough and reliable, Synchro is a type of rotary electrical transformer that is used for measuring the angle of a rotating machine.

The principles of Synchro are similar to those of an electrical transformer except that the iron core of Synchro consists of a rotor and a stator.
Output voltage of Synchro varies in accordance with a rotation angle of a shaft.

It is classified into two types: Torque Synchro and Control Synchro.

Torque Synchro

Torque Synchro is used by connecting a torque transmitter (TX or G) with a torque receiver (TR or M).

A shaft of the receiver rotates in unison with the rotation of a shaft of the transmitter. In other words, the receiver synchronizes exactly with the transmitter.

So you can detect the shaft angle of the torque transmitter by measuring the shaft angle of the torque receiver.

Control Synchro

Control Synchro detects a rotation angle by reading output voltage.

When a shaft of a control transmitter (CX) or of a brushless control transmitter (BCX) is rotated, 3-phase output voltage changes corresponding to the shaft angle. So the shaft angle can be determined by detecting the output voltage.

Structurally, Control Syncro is classified into two types : a brush type and a brushless type.

Synchro Tamagawa comply with the standards JIS, NDS, MIL-S-20708D. The range of product also includes rugged, water-proof and dust-proof versions.
