In both induction and synchronous motors, the AC power supplied to the motor's stator creates a magnetic field that rotates in synchronism with the AC oscillations. Whereas a synchronous motor's rotor turns at the same rate as the stator field, an induction motor's rotor rotates at a somewhat slower speed than the stator field. The induction motor stator's magnetic field is therefore changi… WebSep 5, 2024 · Servo motors are divided into AC servo and DC servo. The basic structure of AC servo motor is similar to that of AC induction motor (asynchronous motor). On the stator, there are two excitation windings Wf and control windings WcoWf with phase space displacement of 90 electrical angle, which are connected with constant AC voltage.
