introduction：Ac servo motor The rotor inside the servo motor is a permanent magnet，Driver controlledU/V/WThree-phase electricity forms an electromagnetic field，The rotor rotates under the action of this magnetic field，At the same time, the encoder with the motor feeds back the signal to the driver，The drive compares the feedback value to the target value，Adjust the rotation Angle of the rotor。The accuracy of the servo motor is determined by the accuracy of the encoder（Line number）
