PROBLEM TO BE SOLVED: To embody the drive circuit of a motor with improved capability to control the current passed through the coils of the motor. SOLUTION: In the drive circuit of a motor provided with a feedback control loop for currents, a voltage command value is compensated near the zero cross point of the output current of an inverter circuit, and thereby dead bands near the zero cross point of the output current of the inverter circuit are removed. |
