Abstract
The present invention relates to a driving of a switched reluctance motor, and in particular to a driving device for an SR motor which can detect a position of a rotor of the SR motor by using a smaller number of sensors than phases, and which can drive the SR motor on the basis of the detected result. At an initial stage of the starting of the SR motor, the position detection is not performed, and a microprocessor sequentially outputs a plurality of control signals, thereby aligning the rotor. After the starting, the microprocessor sequentially outputs the plurality of control signals according to a result detected from a position detection unit.
