ABSTRACT:
The system energizes an SR motor with a current of a level which corresponds to a target rotational speed and a target torque of a rotor. The system includes an energization pattern generator which is intended to provide a smooth rotation of the rotor. The system also includes a direction of rotation detector circuit which detects an oscillation of the rotor in a peripheral direction and a compensator which corrects an energization level in synchronism with the oscillation, thereby suppressing an oscillation of the rotor in the peripheral direction. Finally, the system includes another compensator which corrects an energization level to nullify a deviation of an actual rotational speed with respect to the target rotational speed of the rotor.
