A selsyn, short for self-synchronous motor-generator, refers to a specific type of rotary electrical device that converts an electrical signal into a mechanical rotation or vice versa. Also known as synchro systems, selsyns consist of a uniquely designed motor and generator, where the two are mechanically coupled together to ensure synchronous operation.
The distinguishing feature of a selsyn lies in its ability to transmit information accurately and instantly between two or more remote locations. This is achieved by the motor and generator being electrically connected, allowing the device to receive an input signal at one end and generate an output signal at the other end that precisely indicates the remote machine's position, speed, or other relevant data.
Selsyns are primarily utilized in applications where precise control or tracking is required, such as robotics, radar systems, navigation equipment, and industrial automation. They are favored due to their capability to provide high-resolution feedback and to accurately replicate the position or speed of a driven shaft.
Furthermore, selsyns are commonly used as control elements in dead reckoning systems, where their continuous rotation enables accurate determination and tracking of an object's position. By comparing the transmitted electrical signals with reference information, precise position or motion data can be obtained.
Overall, selsyns serve as crucial components in diverse technological systems, offering a reliable and accurate means of transmitting and converting electrical signals into precise mechanical movements or rotational positions.
