Abstract
A motor-generator that is a rotary electric machine includes a cylindrical stator core having a plurality of teeth that are arranged spaced apart from each other in a circumferential direction and extend in a radial direction; a cassette coil arranged on an outer periphery of each of the teeth; an insulator that has a pawl portion and is interposed between the stator core and the cassette coil; and a wedge that is provided extending between the cassette coils that are adjacent to each other, which fixes the cassette coils with respect to the stator core. The wedge is retained by the pawl portions of the insulators that are adjacent to each other.
