Abstract:
1. A rotating electrical machine comprising: one rotor; and two stators opposed with the rotor being interposed therebetween either on both sides of the rotor in an axial direction or on both sides of the rotor in a radial direction, wherein the two stators generate magnetic fluxes varying either in the axial direction or in the radial direction, wherein the stators are opposed to each other in either said axial direction or said radial direction, wherein each stator has teeth provided in a plurality of portions in a circumferential direction, and stator windings for a plurality of phases, said windings are primary conductors wound around the teeth, the stator windings are wound in concentrated winding, wherein said windings of different phases are wound around teeth adjacent in the circumferential direction in the plurality of teeth, directions of magnetic fluxes generated by stator windings having a same phase in the two stators are in mutually opposite directions with respect to either the axial direction or the radial direction, wherein the stators are opposed to each other in either said axial direction or said radial direction, and the stator windings having the same phase in the two stators are arranged to be shifted from each other by 180 degrees in electrical angle in the circumferential direction.
