Abstract: A motor includes a rotor including a shaft extending along a center axis in a lengthwise direction, the rotor being rotatable about the center axis, a stator opposite the rotor with a clearance between the stator and the rotor in a radial direction, and a housing accommodating the rotor and the stator. The housing includes a tubular portion extending along the center axis, and a bottom portion closing a lower opening of the tubular portion. The tubular portion includes, on its inner peripheral surface, a fitting portion fitted to the stator, and a tapered portion with a diameter gradually decreasing downward and located below the fitting portion. The tubular portion includes, in its outer peripheral surface, a recessed portion with an axial position overlapping the tapered portion and extending in a circumferential direction.

Abstract: A motor includes a rotor with a shaft disposed along a central axis, a stator including coils and facing the rotor via a gap in a radial direction, bus-bars electrically connected to the stator, and bus-bar holders on one side in the axial direction of the stator that are distinct members separated from each other. The coils define coil groups having power systems different from each other. Each of the bus-bar holders holds at least one of the bus-bars different from each other. In each of the bus-bar holders, at least one of the bus-bars held on the bus-bar holder includes a connection terminal electrically connected to an electrical component.

Abstract: A motor includes a first bus bar including a first extension, a second extension, and a first bus bar body including a first corner to which the first extension and the second extension are connected. A holder includes a support to support the first bus bar body, a pair of first walls, and a pair of second walls. The pair of first walls include wall surfaces that face each other in the first perpendicular direction and are spaced by a gap from each other, and extend in the first direction. The pair of second walls include wall surfaces that face each other in the second perpendicular direction and are spaced by a gap from each other, and extend in the second direction. A first space is provided between the pair of first walls and the pair of second walls. The first corner is provided in the first space.

Abstract: A motor includes a first bus bar including a first extension extending in a first direction perpendicular to the axial direction, a second extension extending from an end of the first extension in a second direction perpendicular to the axial direction and intersecting the first direction, and a first bus bar body including a first corner to which the first extension and the second extension are connected. A holder includes a support to support the first bus bar body from another side in the axial direction, a pair of first walls parallel or substantially parallel in a first perpendicular direction and to which the first extension is fitted in the first perpendicular direction, and a pair of second walls parallel in a second perpendicular direction and to which the second extension is fitted in the second perpendicular direction. The pair of first walls include wall surfaces that face each other in the first perpendicular direction and are spaced by a gap from each other, and extend in the first direction.
