Abstract:
A stator for a rotating electric machine facilitates the assembly of the stator coils and restricts its length in the axial direction. The stator includes a stator iron core having a plurality of teeth and a plurality of stator coils each being wound on one of the teeth. The stator coils include terminal stator coils, each having a crossover wire and a lead wire. Each crossover wire is connected to one of the stator coils of the same phase and each lead wire being is connected to an object other than the stator coils of the same phase. Each end of the crossover wires and the lead wires is disposed at a different level; a first level being the closest to the stator iron core. At least one of the lead wires of the terminal stator coils is disposed at least one level apart within the range of levels.
