PURPOSE:To provide a unidirectional salf-starting property of an inductor motor with a simple construction by disposing alternatingly a plurality of sets of the first and second pole teeth and so disposing confronting the first and second auxiliary pole teeth as displaced at predetermined interval directly in the rear of the first and second pole teeth of the respective phases. CONSTITUTION:A plurality of sets of the first and second pole teeth 4 and 5 are disposed to confront north and south poles of permanent magnets 2 and 3 alternatively provided on a rotor 1, and the first and second auxiliary pole teeth 6 (6aX, 6aY, etc.) confronting at infinitesimal interval R each other are disposed directly after the first and second pole teeth of the respective sets. The first and second pole teeth 4, 5 are longitudinally disposed through auxiliary pole teeth 6 in the same polarity at both sides thereof as energized. The respective auxiliary pole teeth 6a, 6b,... are so disposed, in case, for example, that the rotating direction of the rotor 1 is represented by K, as to approach the first and second pole teeth 4, 5 located directly thereafter nearer than the first or second pole teeth 4, 5 located directly therebefore. |
