What is the function of stator coils in synchro transmitters and receivers?

The correct function of stator coils in synchro transmitters and receivers is to serve as secondary windings. In a synchro system, the stator is designed to sense the magnetic field created by the rotor. The rotor, which is connected to a mechanical input, generates a magnetic field that induces a voltage in the coils of the stator. These induced voltages represent the position of the rotor, allowing the synchro system to convert mechanical movement into an electrical signal, essentially transmitting the measured angle or position.

The design and operation of synchro systems depend heavily on the interaction between the rotor and stator, making the role of the stator coils as secondary windings crucial. By transforming the magnetic energy into an electrical signal via these windings, synchros can effectively relay information about position and rotation in various applications.
