Abstract:
1. A motor generator comprising: a stator in which a winding is wound around each of a plurality of stator teeth provided on a stator core; a rotor having a plurality of permanent magnets larger in number than the number of stator teeth, the plurality of permanent magnets being arranged circumferentially on a rotor core at equal intervals; wherein the stator teeth are formed of a first stator teeth section having a plurality of groups of adjacent stator teeth around which a winding to which the same phase voltage is applied is wound and in which winding directions of the windings around the adjacent stator teeth are opposite to each other, and a second stator teeth section formed of one or more stator teeth each having a different phase, the one or more stator teeth of the second section of teeth being positioned between and adjacent to each of a corresponding plurality of groups of adjacent teeth of the first section of teeth; wherein when the second stator teeth section has a plurality of stator teeth, winding directions of the adjacent stator teeth are opposite to each other; wherein electric power is independently input and output with respect to each of the windings of the first and second stator teeth sections; and wherein each respective winding of each stator teeth section receives the same respective phase voltage.
