Abstract:
A rotary electric motor includes a cylindrical rotor having an outer peripheral side, a stator provided to surround the outer peripheral side of the rotor with a gap between the stator and the rotor, and a load side bracket having a recess and provided on a load side of the stator. The stator includes stator coils and a stator core having teeth portions around which the stator coils are wound. A load side coil end of each of the stator coils protrudes from a load side end face of the stator core. At least two of an inner peripheral surface, an outer peripheral surface, and an end face of the load side coil end contact an inner surface of the recess via an insulator.
