ABSTRACT:
A stator for a multiple-phase rotary electric machine is provided with a stator core with slots and a coil formed of a plurality of windings for individual phases. Each winding has slot-accommodated portions accommodated 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 one of the return portion. The first and second windings are jointed to each other via a joined portion disposed in a specific slot among the slots.
