Original Abstract Submitted

a motor may include a rotor; a stator comprising 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 include a plurality of first holes through which refrigerant is injected toward a first coil end of the coil protruding from the first end face of the stator core. at least one of the plurality of first holes may be covered with at least one mesh filter.
