selsyn
Noun: 1. A type of electromechanical device: A selsyn is a system that uses electrical signals to synchronize the angular position or rotation of two or more physically separated devices. It consists of matched components (typically a transmitter and a receiver) so connected that the receiver motor precisely follows the movement of the transmitter generator.
A selsyn is used for remote indication and control, ensuring two or more units move in unison without a mechanical connection. * The selsyn system allowed the rudder position on the bridge to be accurately displayed in the engine room. * In older aircraft, a selsyn transmitted the landing gear position to the cockpit indicator. * The engineer checked the selsyn units to ensure the remote radar antenna was correctly aligned.
- Selsyn System: Refers to the complete setup of synchronized generator and motor units.
- The factory's conveyor belts were coordinated using a complex selsyn system.
- Selsyn Dial: A gauge or indicator driven by a selsyn receiver.
- The operator read the temperature from a selsyn dial located across the room.
- Synchro: A more modern and general term that has largely replaced "selsyn" in technical contexts. The devices are functionally identical.
- The servo mechanism was controlled by a synchro transmitter.
- Autosyn: A proprietary brand name for a type of selsyn/synchro device.
- Resolver: A related type of rotary electrical transformer used for position sensing, often providing more precise data than a basic selsyn.
- Synchro
- Synchronous transmitter/receiver
- Remote indicator system
- Transmitter (Generator): The selsyn unit that sends the electrical signal corresponding to its shaft position.
- Receiver (Motor): The selsyn unit that receives the signal and rotates its shaft to match the transmitter's position.
- Torque Receiver: A type of selsyn receiver designed to move a light indicator needle.
- Control Transformer: A type of selsyn receiver used in servo systems to produce a voltage error signal.
- a system consisting of a generator and a motor so connected that the motor will assume the same relative position as the generator; the generator and the motor are synchronized
