  • Publication number: 20250112515
    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.

  • Publication number: 20250067261
    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.

  • Publication number: 20250038602
    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.

  • Publication number: 20250038608
    Abstract: A stator of a rotating electric machine includes: a stator core including a yoke; an insulator having a plurality of insulator extension portions and a plurality of insulator inner walls each extending from the corresponding insulator extension portion; and a cover. The cover has an insertion plate extending in an axial direction of the yoke. The insulator inner walls adjacent to each other cooperate to have a pair of space-forming walls. One of the pair of space-forming walls is spaced from the other of the pair of space-forming walls in a circumferential direction of the yoke, and cooperates with the other of the pair of space-forming walls to define an insertion space into which the insertion plate is inserted. The insertion plate is configured to come into contact with the pair of space-forming walls with the insertion plate inserted into the insertion space.

  • Publication number: 20250020123
    Abstract: An electric compressor includes a rotary shaft, a compression part, a motor including a stator, and a housing. The stator includes a stator core, coils corresponding to a plurality of phases, an insulator, coil ends, first leads of the winding wires, a neutral connection portion, and a cover member. The cover member has a cover end surface opposite from the coil ends. The cover end surface has an accommodation portion in which the neutral connection portion is accommodated. The first leads each include a covered portion, and a non-covered portion. The non-covered portion includes an extension portion continuous with the neutral connection portion extending out from the accommodation portion by a predetermined length. The cover end surface includes a first surface, and a second surface. At least the first surface has a through hole. The first surface is positioned farther from the coil ends than the second surface is.

  • Publication number: 20240329593
    Abstract: There are provided a developer accommodating portion for accommodating the developer, a discharge portion formed with a discharge opening for discharging the developer accommodated in the developer accommodating portion, and an engaging portion 30. The engaging portion 30 is engaged with an engaged portion 11b with a mounting operation of a developer supply container 1 to displace a developer receiving portion 11 in an upward direction U so that the receiving opening communicates with the discharge opening. The engaging portion 30 has a holding portion 31 which is provided rotatably about a rotation shaft 41 and is provided with holding portion 21 to be engaged with the engaged portion 11b to hold the engaged portion 11b. With the mounting operation, the engaging portion 30 rotates about the rotation shaft 41 so that the engaged portion 11b held by the holding portion 31 moves upward U.

  • Publication number: 20240213843
    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.

  • Publication number: 20240069468
    Abstract: With a mounting operation of a supply container, a supported portion 11b of a developer receiving portion 11 is supported by a receipt supporting portion 30c of a lifting portion 30. With further mounting operation, a shutter sliding portion 30b of the lifting portion 30 slides on a shutter inclined portion 4f of a shutter 4. The developer receiving portion 11 is displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter 4, the lifting portion 30 supporting the supported portion 11b of the developer receiving portion 11. By this, a load required for movement of the developer receiving portion 11 is reduced to achieve smooth mounting of the supply container.

  • Patent number: 11852991
    Abstract: A developer supply container includes a developer accommodating portion accommodating developer, and a developer discharging portion in fluid communication with the developer accommodating portion. The developer accommodating portion is rotatable about a rotational axis and relative to the developer discharging portion, with the developer discharging portion being provided with a developer discharge opening at a bottommost side of the developer discharging portion and configured to permit discharging the developer to outside of the developer supply container. A lifter is linearly liftable relative to the developer discharging portion in a direction perpendicular to a horizontal plane that includes the rotational axis when the developer supply container is oriented with the developer discharge opening positioned at a bottom side of the developer discharging portion.
