<p>The d-phase current and q-phase current perpendicular to the d-phase current in the direction of the magnetic flux generated by means of a field from the driving current and rotor phase of an AC servo motor through d-q transformation and found. The current of the servo motor is controlled by using a DC system by setting the d-phase current at zero and using the q-phase current as a current command. The torque drop of the motor is reduced by suppressing the influence of magnetic saturation by advancing the phase of the q-phase current command which is an effective component of the current command when the magnetic saturation occurs.</p> |
