ABSTRACT:
A stator for a multiple-phase rotary electric machine provided a stator core with slots and a coil formed of a plurality of windings for individual phases. Each winding has slot-accommodated portions held in different slots, turn portions connecting the slot-accommodated portions outside of the slots in an axial direction, and a return portion that connects two of the turn portions and changes a winding direction of the winding at given slots. The turn portions include specific turn portions which are the same in a circumferential position as the turn portion connected to the one of the return portion. The specific turn portions are located, in a radial direction, to be drawn apart from the rotor than the slot-accommodated portions connected to the specific turn portions.
