Fonction

A synchro is a type of rotary electrical transformer that is used for measuring the angle of a rotating machine such as an antenna platform.

Technique

The primary winding of the transformer, fixed to the rotor, is excited by an AC current, which by electromagnetic induction causes currents to flow in three star-connected secondary windings fixed at 120 degrees to each other on the stator. The currents can be used to directly drive an electric motor that will rotate in unison with the synchro. In the latter case, the whole device is also called a selsyn (a word made up from self-synchronizing).
