Abstract:
An object is to provide a rotating electric machine offering a high output and high efficiency by balancing inductance of each phase even if a stator is used in which stator windings of different phases are disposed in a slot of a stator core in a three-phase winding. A stator 5 includes a stator core 6 having a plurality of slots arrayed circumferentially and opening to an inner peripheral surface and a stator winding 7 wound in each of the slots. The stator winding 7 is divided into at least two for each phase (7U-A, 7U-B, 7V-A, 7V-B, 7W-A, 7W-B). After insertion of the stator core 6, the stator winding of each phase is connected in parallel or in series. The stator winding of each phase is disposed in slots such that combined inductance of different phases is equalized.
