Motor generator

A motor generator is provided with a stator (10) having a winding (6, 7) around each of a plurality of stator teeth (2, 3), and a rotor (11) having a plurality of permanent magnets (13) by the number larger than that of the stator teeth (2, 3), arranged in the circumferential direction at equal intervals. The stator teeth (2, 3) are formed of a first stator teeth section (4) including a plurality of stator teeth groups I, II, and III each including the adjacent stator teeth (2) around which a winding (6) to which the same phase voltage is applied is wound and in which winding directions of the stator teeth (2) are opposite to each other, and a second stator teeth section (5) including a stator teeth (3) having a winding (7) wound therearound and being placed among stator teeth groups (I, II, III) of different phases such that electric power is independently input and output with respect to the first and second winding sections (8, 9). 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.
