摘要： PROBLEM TO BE SOLVED: To provide a switched reluctance motor in which a torque can be easily improved without increasing a size.
SOLUTION: The switched reluctance motor 10 includes the salient pole 12a of a stator 12 and the salient pole 14a of a rotor 14 present on a plane including the rotary shaft 18 of the rotor 14, at least parts of the outlines 12b and 14b of which salient poles 12a and 14a become non-parallel with the rotary shaft 18 of the rotor 14. As a result, the length of the outlines opposed on the plane when the salient pole 14a of the rotor 14 approaches the salient pole 12a of the stator 12 is increased as compared with the case that the outlines of the salient poles 12a, 14a are parallel to the rotary shaft 18, and the attraction area when the salient pole 14a of the rotor 14 approaches the salient pole 12a of the stator 12 is increased. As a result, the rotary torque of the rotor 14 is improved. At this time, since only the salient poles 12a, 14a are changed, the switched reluctance motor 10 is not increased in size.
