AC torque synchro

AC torque synchro

The AC torque synchro also consists of a transmitter and receiver. These are similar in form; stator and rotor windings. Interconnections.

  The rotors consist of an iron core, single winding, slip-rings, and brushes. Stators consist of three sets of windings each at 120 degrees to each other.

 The rotors of the transmitter and receiver are supplied from the same power supply (normally 26 V AC); this alternating supply flows through both the rotor coils via slip-rings.

 Current flowing through the transmitter’s rotor creates an alternating magnetic field; this induces currents into each of its stator windings.
