摘要:
In a rotating electrical machine, when a stator winding is wound in concentrated winding, an improvement in performance is achieved by reducing a magnetomotive force harmonic without reducing a fundamental wave magnetic flux generated by a stator. A rotating electrical machine (10) includes a rotor (18), and two stators (14, 16) opposed with the rotor (18) being interposed therebetween either on both sides of the rotor (18) in the axial direction or on both sides of the rotor (18) in the radial direction. Stator windings (22) provided in a plurality of portions in the circumferential direction of each stator (14, 16) are wound in concentrated winding. The directions of magnetic fluxes generated by stator windings (22) having the same phase in the stators (14, 16) are in mutually opposite directions with respect to either the axial direction or the radial direction. The stator windings (22) having the same phase in the stators (14, 16) are arranged to be shifted from each other by 180 degrees in electrical angle in the circumferential direction.
