Abstract
A stator of a rotary electric machine includes an annular stator core with a plurality of slots arranged in a circumferential direction, a stator winding formed by three phases of phase windings wound around the slots, and neutral wires for commonly connecting ends of the phase windings together in star-connection. Each of the phase windings has two partial windings that are electrically connected in parallel, ends of at least two sets of the partial windings formed by combining two partial windings among the total of six partial windings in different phases and the ends of the neutral wires are connected electrically, and the partial windings connected to both ends of each neutral wire include all the phases.
