MOTOR

A motor may include a rotor; a stator including a stator core and a coil; a housing that houses the rotor and the stator; and a first annular member that provides a seal between a first end face of the stator core in an axial direction of the stator core and an inner wall surface of the housing. The first annular member may be arranged so as to surround an outer periphery of a first coil end. The first annular member may include first holes through which refrigerant is injected toward the first coil end. At least one opening of the first holes may have a shape in which a maximum value of a first width, which is a dimension in a circumferential direction of the stator core, is greater than a maximum value of a second width, which is a dimension in the axial direction of the stator core.
