Selsyn (self synchronous) motors are electromechanical devices used for the transmission of angular-positional data or torque between remote locations. The typical system consists of a transmitter and a receiver, connected by three wires, and powered by a common single-phase 110VAC. No mechanical connection exists between the units. The transmitter and receiver may be identical units. Rotation at one location will create the same rotation in the other. The accuracy is typically +/- one degree depending on the frictional torque of the load. One transmitter can drive multiple receivers.
Angular-data transmission applications
Convenient and accurate angular-position data can be transmitted to +/- one degree of accuracy. When the input shaft of the transmitter is rotated, the output shaft of the receiver follows. Typical installations are for remotely reading the position of a valve, gate, drawbridge, door, electrical contactor or cover.
Torque transmission applications
The receiver will follow the transmitters' angular position, and create torque to drive a load at a remote location. In this case the receiver is acting as a motor in synch with the transmitter. Speeds up to 1200 RPM are practical with the 110 VAC 50 or 60 Hertz units. Typical installations are the synchronization of the audio/video in movie equipment, valve actuation, factory automation, and processing.
