Abstract: A stator may include a back iron having a cylindrical shape and extending along an axial direction; a plurality of teeth provided on an inner circumferential surface of the back iron; and a stator coil provided on the plurality of teeth. A plurality of coolant passages may be arranged in a circumferential direction in circumferential regions of the back iron and the plurality of coolant passages may extend along the axial direction to a first end face of the back iron. The plurality of coolant passages may include a coolant passage located in an uppermost portion of the back iron in a vertical direction and a coolant passage located in a lowermost portion of the back iron in the vertical direction. At the first end face of the back iron, an arrangement of the plurality of coolant passages may have two-fold symmetry and may not have four-fold symmetry.

Abstract: 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.

Abstract: 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.

Abstract: A motor may include: a stator comprising a stator core and a coil; a housing that houses the stator; and a first annular member that provides a seal between a first end face of the stator core and an inner wall surface of the housing. The inner wall surface may include a first inner wall surface radially facing a first coil end of the coil and a second inner wall surface facing the first coil end. The first annular member may include: a first portion having a cylindrical shape 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. The first portion may include a plurality of first holes through which refrigerant is injected toward the first coil end.
