The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electric motor controlled by the driver forms an electromagnetic field. The rotor rotates under the action of the magnetic field. At the same time, the encoder feedback signal from the motor is supplied to the driver. The driver according to the feedback value and target. The values are compared to adjust the angle at which the rotor rotates. The accuracy of the servo motor is determined by the accuracy (number of lines) of the encoder.
The structure of the AC servo motor stator is basically similar to that of a capacitive split phase single-phase asynchronous motor. The stator is equipped with two windings with 90° difference between each other, one is the field winding Rf, which is always connected to the AC voltage Uf; the other It is the control winding L, which is connected to the control signal voltage Uc. Therefore, the AC servo motor is also called two servo motors.
