Abstract
A motor includes a rotor and a stator, the stator having a stator core and an electrical insulator assembly at each end of the stator core. The electrical insulator assemblies each have an outer wall part extending in a circumferential direction and facing a yoke of the stator core and a plurality of extending parts extending radially inward from the outer wall part and facing teeth of the stator core. The outer wall part has a radial thickness and includes a plurality of radial notches for guiding extensions of the stator winding between an inner peripheral surface and an outer peripheral surface of the outer wall part. The outer peripheral surface of the outer wall part adjacent to the notches is configured such that the radial thickness of the outer wall part gradually decreases toward the notch along a circumferential direction of the yoke.
