摘要： 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.

摘要： It is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible. A stator (6) includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles (6a, 6b, 6c). The stator magnetic poles (6a, 6b, 6c) are each composed of an arcuate stator core (13) having a plurality of axially extending claw poles (16b) and a circumferentially elliptically wound stator winding (14). The stator magnetic poles (6a, 6b, 6c) are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles (6a, 6b, 6c) can improve a cooling effect.
