Servo motor, according to the requirements of the control command, the power is amplified, transformed and regulated, so that the torque, speed and position control of the output of the drive device is very flexible and convenient.

Because of its “servo” performance, it is named as a servo motor. Its function is to convert the input voltage control signal into the angular displacement and angular velocity output on the axis drive control object.

Servo motors are generally divided into two categories: DC servo motors and AC servo motors.

The rotor inside the AC servo motor is a permanent magnet, and the UN/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field, and the encoder with the motor gives feedback signals to the drive

The driver adjusts the rotation Angle of the rotor according to the feedback value compared with the target value.

When the AC servo motor has no control voltage, only the pulsating magnetic field generated by the excitation winding is in the stator, and the rotor is stationary. When there is a control voltage, a rotating magnetic field is generated in the stator, the rotor rotates in the direction of the rotating magnetic field, in the case of constant load, the speed of the motor changes with the size of the control voltage, when the phase of the control voltage is opposite, the servo motor will reverse.
