A06B-1467-B123#0A21 FANUC Robot Educator
The working principle of DC servo motor is basically the same as that of ordinary DC motor. Electromagnetic torque is generated by the action of armature flow and air gap flux to make the servo motor rotate. Armature control is usually used to change the speed by changing the voltage while keeping the excitation voltage constant. The lower the voltage, the lower the rotational speed. When the voltage is zero, stop rotating. Because when the voltage is zero, the current is zero, so the motor does not produce electromagnetic torque, nor does it spin.
Dc servo motor is widely used in numerical control system, but DC servo motor also has some disadvantages: its brush and commutator are easy to wear; Limit of maximum speed of motor and application environment; The structure is complex, the manufacture is difficult and the cost is high.
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.
