Description
Synchro,control Transformer
CAGE
05088

A synchro consisting of a stator and rotor inductively coupled. The electrical output of the rotor is dependent upon both the position of the rotor and the electrical input to the stator from a transmitter synchro or a differential synchro. Does not include variable resistors, goniometers, or variable transformers.
