A06B-1404-B103#0C02 FANUC AC spindle motor, in an AC servo motor, in addition to the requirement that the motor not “rotate”, it is also required to change the magnitude and phase of the voltage applied to the control windings to change the magnitude and direction of the motor speed.
According to the theory of rotating magnetomotive force, a rotating magnetic field is produced by the joint action of excitation winding and control winding, and the rotation direction of the rotating magnetic field is from the winding with phase advance to the winding with phase lag. By changing the phase of the control voltage in the control winding, the lead-lag relationship of the two-phase winding can be changed, so as to change the rotation direction of the rotating magnetic field, and the speed direction of the AC servo motor will also change. Changing the size and phase of the control voltage can change the flux of the rotating magnetic field, thus changing the electromagnetic torque of the motor, and the speed of the AC servo motor will also change.
The speed control methods of AC motor include amplitude control, phase control and amplitude phase control.
