PURPOSE:To contrive to reduce the cost of a 1-slot 1-coil winding motor and to improve the performance thereof by limiting the number of windings to the minimum through specifying the relation between the number of phases, stator slots and rotor magnetic poles in the 1-slot 1-coil winding motor. CONSTITUTION:In a 1-slot 1-coil winding motor, the condition S/P=m/n is satisfied when the number of phases is (m) and a natural number excepting a multiple of the number of phases is (n) and when the number of slots 2 of a stator 1 is S and the number of magnetic poles of a rotor 3 is P. To be concrete, e.g., the number of slots 2 of the stator 1 is 8 and the number of magnetic poles of the rotor 3 is 4. Also, coils 4, 5 are successively wound round stator teeth 6.... That is, one coil 4, as shown by a solid line, is wound round a tooth 6a, then round a tooth 6c and further round teeth 6e and, also, the other coil 5, as shown by a broken line, is wound round a tooth 6h, then round a tooth 6b and further round teeth 6d and 6f. That is, the motor is constituted as 1-slot 1-coil winding motor. |
