Control Methods Of AC Servo Motors

The control methods of AC servo motors mainly include the following:

Amplitude control: In this control method, the phase of the control voltage remains unchanged, and the control is only carried out by changing the amplitude of the control voltage.

Phase control: In this control method, the amplitude of the control voltage remains unchanged, and the control is only carried out by changing the phase of the control voltage.

Amplitude-phase control: In this control method, the amplitude and phase of the control voltage are changed at the same time for control.

Control mode of AC servo system:

There are three main control modes of AC servo system:

Position control mode: It can accurately control the number of revolutions of the servo motor, which is suitable for occasions where the moving distance of the actuator needs to be accurately controlled.

Speed ​​control mode: The servo drive can work without inputting a pulse signal, which is suitable for occasions where the motor speed needs to be adjusted and the speed needs to be maintained at a stable level.

Torque control mode: The output force of the motor is controlled by adjusting the output torque.
