ABSTRACT:
A motor generator is provided with a stator having a winding around each of a plurality of stator teeth, and a rotor having a plurality of permanent magnets by the number larger than that of the stator teeth, arranged in the circumferential direction at equal intervals. The stator teeth are formed of a first stator teeth section including a plurality of stator teeth groups I, II, and III each including the adjacent stator teeth around which a winding to which the same phase voltage is applied is wound and in which winding directions of the stator teeth are opposite to each other, and a second stator teeth section including a stator teeth having a winding wound therearound and being placed among stator teeth groups of different phases such that electric power is independently input and output with respect to the first and second winding sections. This makes it possible to reduce the space and the cost while inputting/outputting the electric power through different channels and allowing arbitrary design of the electric power distribution.
