Production method for rotating electric machine and stator coils, and electric power steering motor
Abstract:
A stator of a rotating electric machine includes a stator core, and multiphase stator coils incorporated in the stator core. The stator core is formed by connecting a plurality of split core pieces. Each of the stator coils is wound around a coil bobbin installed on the outer periphery of the tooth portion of a respective one of the core pieces, by a concentrated winding method; and around mutually adjacent tooth portions, the respective coils that have the same phase and mutually different in the winding direction are continuously wound. A crossover wire for connecting the first stator coil wound around the first tooth portion and the second stator coil wound around the second tooth portion, is located at a position further toward the central side in the axial direction of the coil bobbin than the end portion of the coil bobbin, inclusive of this end portion.
