Item Name:
SYNCHRO , CONTROL TRANSFORMER
Definition:
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.
