A motor comprising:

• a stator comprising a stator core and a coil;
• a housing that houses the stator;
• and
• a first annular member that is insulative and provides a seal between a first end face of the stator core in an axial direction of an axis of the stator core and an inner wall surface of the housing,
• wherein
• the coil comprises a first coil end protruding from the first end face,
• the inner wall surface comprises a first inner wall surface radially facing the first coil end and a second inner wall surface facing the first coil end in the axial direction,
• the first annular member comprises:
• a first portion having a cylindrical shape about the axis and interposed between the first coil end and the first inner wall surface;
• and
• a second portion protruding radially inward from the first portion and interposed between the first coil end and the second inner wall surface, and
• the first portion comprises a plurality of first holes through which refrigerant is injected toward the first coil end.
