Working Principles of an AC Servo Motor Check out the full blog post over at https://realpars.com/servo-motor/ The synchronous AC servo motor consist of stator and rotor. The stator consists of a cylindrical frame and stator core. The armature coil wound around the stator core and the coil is connected to a lead wire through which current is provided to the motor. The rotor consists of a permanent magnet and this differs with the asynchronous induction type rotor in that the current in the rotor
