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.

摘要： There is provided a rotating electric machine capable of preventing a coolant from being retained at an outer surface of a rotor. This rotating electric machine includes a rotation shaft provided so as to be rotatable, a core body secured to the rotation shaft, a permanent magnet embedded in the core body, and an end plate provided so as to be opposed to an axial end surface of the core body. A first coolant channel is formed in the rotation shaft to allow a coolant to flow therethrough. A second coolant channel is formed between the end plate and the axial end surface of the core body to communicate with the first coolant channel. A partition wall that partitions the second coolant channel in a circumferential direction and a path wall that guides the coolant in the second coolant channel toward an outer peripheral edge region of the axial end surface where the permanent magnet is placed are formed inside the second coolant channel.
