A switched reluctance motor has a rotor and a stator. The stator has first and second stator magnetic pole groups sequentially placed in an axial direction of the rotor. First and second stator magnetic poles in each group are alternately arranged on a same circumference. The first stator magnetic poles are placed every electrical angle 2&pgr; and reversely magnetized to each other. The second stator magnetic poles are placed every electrical angle 2&pgr; and reversely magnetized to each other. The first magnetic pole is apart from the second magnetic pole by electrical angle &pgr;. Each stator magnetic pole in the first stator magnetic pole group is apart from that in the second magnetic pole group by electrical angle &pgr;/2 in the circumferential direction.
