TRANSMITTER TAMAGAWA SYNCHRO TS12N7E11 , 110V AC

Synchro is a type of rotary electrical transformer that is usedfor measuring the angle of a rotating machine.
Synchro is sometimes called selsyn with aliases.
It is classified into twotypes : Torque Synchro and Control Synchro.
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.
