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: A step of inserting an insulating paper into a slot of a stator core (second step) is performed, a step of placing a jig at a position that is on a side opposite to a side from which a segment coil is inserted into the slot of the stator core and that overlaps with a protrusion when viewed in an inserting direction of the segment coil (third step) is performed, and then a step of inserting the segment coil into the slot (fourth step) is performed. Therefore, even when the insulating paper is dragged by the segment coil in the process of inserting the segment coil into the slot, the insulating paper abuts the jig and the movement of the insulating paper is restricted, thereby suppressing displacement of the insulating paper from the slot.

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 have a cylindrical shape about an axis of the stator core. The first annular member may include at least one first hole and at least one second hole through which refrigerant is injected toward a first coil end. The at least one first hole may be located on a first plane perpendicular to the axis. The at least one second hole may be located on a second plane that is perpendicular to the axis and spaced apart from the first plane in the axial direction.

Abstract: A first U-shaped part that is bent so as to form a pair of opposite surfaces facing each other, and a second U-shaped part that is bent so as to form a pair of opposite surfaces facing each other are provided side by side in a bus bar main body of a neutral conductor bus bar. One of the first pair of opposite surfaces and one of the second pair of opposite surfaces are located in the same plane, and the other of the first pair of opposite surfaces and the other of the second pair of opposite surfaces are located in the same plane. A temperature sensor is retained by being inserted through a gap between the first pair of opposite surfaces and a gap between the second pair of opposite surfaces.

Abstract: A stator includes a stator core and an insulator. The insulator includes a main body and a wall. An adhesive is attached to a portion of a triangular gap between the wall of the insulator and a yoke of the stator core. The adhesive is expandable, and adheres and fixes the insulator to the stator core by expanding to fill in the gap by being heated. Also, a stator manufacturing method includes attaching an adhesive to the wall of the insulator or an inside wall of the yoke, installing the insulator on a tooth, and heating the stator core and the insulator.
