Abstract

A rotating electric machine includes a stator core, multi-phase stator coils and a rotor. The stator core has teeth and slots. Each of the multi-phase stator coils is comprised of phase windings received in the slots of the stator core. The rotor radially faces the teeth of the stator core. Between the multi-phase stator coils, there is provided, at a maximum, a phase difference of θin electrical angle. Each of the teeth of the stator core has a radially-extending portion and a distal end portion. The distal end portion has skew-forming portions arranged in an axial direction of the stator core. Each of the skew-forming portions has a distal end surface facing the rotor. Circumferential center positions of the distal end surfaces of the skew-forming portions are circumferentially offset from one another by, at a maximum, θin electrical angle. Moreover, the relationship of θis satisfied.
