Abstract
2m sets (m being a natural number of 2 or more; and m=2 in embodiments) of teeth (to) and 2m−1 slots () are disposed alternately in an axial direction; those of windings () accommodated in the slots (), which are each accommodated in the slots () spaced apart by m from each other, are connected in line, so that exciting directions are opposite; and phases of magnetic fluxes passed through the teeth (to) are displaced by 360°/2m from one another. Therefore, a thin and high-powered claw pole motor can be produced by disusing a portion of the winding which does not contribute to a torque (i.e., a crossover portion) and commonly using a magnetic path in each phase through return passes (to). Moreover, a magnetic circuit of a wave winding motor is formed and hence, the output torque can be increased, as compared with a salient pole concentrated winding motor.
