Abstract

See full text

A motor includes a rotor, a stator core, a stator coil, and a shower pipe. An upper part of an outer circumferential surface of the stator core includes a circumferential groove that extends in a circumferential direction of the stator core. Axial grooves are located at positions that are spaced apart from each other in the circumferential direction, and extend in a direction that intersects the circumferential groove. The axial grooves each open in opposite end faces of the stator core in an axial direction of the rotary shaft. Each axial groove includes opposite ends in the axial direction. The opposite ends have a groove width that becomes narrower as the opposite ends become farther from the circumferential groove.
