Abstract: A stator for an electric motor 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. The back iron may be provided with a coolant passage extending along the axial direction to a first end face of the back iron. The coolant passage may include a first section extending from the first end face and a second section adjacent to the first section. A dimension of the first section of the coolant passage in a radial direction of the stator may be different from a dimension of the second section of the coolant passage in the radial direction.

Abstract: A harness clamp includes a harness clamp body including a base part, an upright part, a fixing part, a folding back part, a first elongated part, and a second elongated part. A distal end of the second elongated part and the upright part define a first gap. A fourth bent part and the base part define a second gap. The base, folding back, and first elongated parts define a first clamp space to clamp a harness. The base, upright, and second elongated parts define a second clamp space to clamp the harness deformed through the second gap from the first clamp space. Where a length of the first gap is A, a length of the second gap is B, a diameter of the harness is ϕ, and a maximum diameter of the deformed harness is a, a relationship that B

Abstract: The motor includes a stator core, a coil wound around the stator core, a neutral bus bar connected to the coil, and a bus bar holder that holds the neutral bus bar. The bus bar holder includes a coolant flow path capable of receiving a coolant for the motor and also supplying the coolant to a coil end exposed from 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.

Abstract: Each of two plug connectors includes a main body configured to retain a plurality of electric wires and a pair of push members protruding from both sides of the main body along a first direction. In connector mating operation, the two plug connectors are respectively inserted into associated receptacle connectors in a state where the two plug connectors are mechanically coupled or bound to a relative positional relationship by a jig in a position where the pair of push members in one of the two plug connectors are displaced from the pair of push members in the other of the two plug connectors along a second direction orthogonal to the first direction.

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.
