Abstract: A motor-driven compressor includes a compression unit, a motor including a stator, and a housing. The stator includes a stator core, coils of multiple phases, an insulator, a phase-to-phase insulation sheet, and a cover member. The cover member includes an annular cover end wall and a tubular cover inner wall that extends toward the insulator inner wall from a radially inner portion of the cover end wall. The cover end wall includes a conical tapered wall that is inclined such that the distance between the cover end wall and the insulator inner wall decreases as the cover end wall extends toward the cover inner wall. The tapered wall is continuous with the cover inner wall.

Abstract: A motor includes a stator having a core and a plurality of radially inwardly extending teeth defining slots therebetween. Each tooth has a tip having a pair of circumferentially protruding tooth projections. A first insulation sheet is inserted between each pair of the teeth and has a body part and a pair of first end parts formed by folding both ends of the body part toward each other. A second insulation sheets is arranged between the winding parts of adjacent teeth and has a body part and a pair of second end parts formed by folding both ends of the body part away from each other. The tooth projections, the second end parts and the first end parts are arranged in this order from radially inside to outside and overlap radially.

Abstract: A coil is formed by a winding wound in a concentrated manner over multiple layers around a tooth and an insulator extension. The insulator extension includes an outer end face located on a side opposite to a stator core. A first turn of the winding that forms a first layer of the coil includes a winding start portion that extends through a first innermost part along a first tooth side surface and a portion that is wound around an outer end face of the insulator extension. The outer end face includes a protrusion protruding from a portion of the outer end face that is closer to an insulator base than the first turn and relatively close to the winding start portion. The winding that forms a specific layer of the coil is extended through a second innermost part along a second tooth side surface and then arranged on the protrusion.

Abstract: Projections are provided on bottom surfaces of U-phase through-grooves. This configuration ensures a sufficient engagement amount of each projection with a corresponding insertion portion as compared to a case in which the projections are provided on the end of an insulator on the side opposite to a stator core. As a result, each projection is stably engaged with the corresponding insertion portion. This allows the cover to be stably attached to the insulator.

Abstract: A motor includes a rotor and a stator, the stator having a stator core and an electrical insulator assembly at each end of the stator core. The electrical insulator assemblies each have an outer wall part extending in a circumferential direction and facing a yoke of the stator core and a plurality of extending parts extending radially inward from the outer wall part and facing teeth of the stator core. The outer wall part has a radial thickness and includes a plurality of radial notches for guiding extensions of the stator winding between an inner peripheral surface and an outer peripheral surface of the outer wall part. The outer peripheral surface of the outer wall part adjacent to the notches is configured such that the radial thickness of the outer wall part gradually decreases toward the notch along a circumferential direction of the yoke.

Abstract: A stator of a rotating electric machine includes: a stator core including a yoke; an insulator having a plurality of insulator inner walls; a cover; a first insulating member; and a second insulating member. The cover has an insertion plate extending in an axial direction of the yoke. The insertion plate has a support surface that is located in a space between the insulator inner walls adjacent to each other in a circumferential direction of the yoke and located inward of the second insulating member to support the second insulating member in a radial direction of the yoke. The support surface is located outward of a slot opening in the radial direction of the yoke when viewed in the axial direction of the yoke.
