A magnetic rotor (5) is provided inside a stator armature (1) of a reluctance motor with an air gap between them. Two salient poles (5a, 5b), each having a width that is 2.5 times each of angular intervals among adjacent slots (1a, 1b, . . . , 1h) of the stator armature (1), are arranged on the outer peripheral portion of the rotor (5). Magnetic fluxes generated by energizing armature coils (2h, 2d) of magnetic poles (4h, 4d) that are not situated at positions where torque is produced are added to magnetic fluxes generated by energizing armature coils (2a, 2e) of magnetic poles (4a, 4e) that are situated at positions where torque is produced in a direction indicated by arrow R. As a result, leakage fluxes Fa, Fb between the magnetic poles (4a, 4e) and the salients (5a, 5b) of the rotor (5) increase, causing the torque to increase. <IMAGE> |
