ABSTRACT:
The invention detects vibrations of a motor by a vibration detection means, compares the detected vibration detection value with a reference value using control means, and changes the voltage to be applied to each of coils of the respective excitation phases until the vibration detection value reaches the reference value, thereby controlling the excitation currents that flow through the coils of the respective excitation phases to reduce the vibrations of the motor.
