  • Publication number: 20200336026
    Abstract: A vehicle electric motor including: a tubular-shaped stator core constituted by laminated steel sheets; a casing including an outer circumferential wall and a bottom wall, and storing therein an axial end portion of the stator core; a casing cover including an outer circumferential wall and a bottom wall, and storing therein another axial end portion of the stator core, and a rotor disposed inside the stator core. The stator core includes fastened portions protruding radially outwardly from respective portions of an outer circumferential surface of the stator core which are circumferentially spaced apart from each other. The stator core is fastened at the fastened portions to the bottom wall of one of the casing and the casing cover. The other of the casing and the casing cover includes protrusion portions protruding from its inner wall surface toward the stator core so as to restrain inclination of the stator core.

  • Publication number: 20200153310
    Abstract: A vehicle electric motor including: a tubular-shaped stator core constituted by electromagnetic steel sheets that are laminated on each other; a rotor disposed inside the stator core so as to be rotated about an axis; and a housing storing therein the tubular-shaped stator core and the rotor, and including a circumferential wall and axially opposite end walls that are opposed to each other in a direction parallel with the axis. The stator core is fixed at one of its axially end portions to one of the axially opposite end walls of the housing. The housing includes a stator-core-inclination restraining portion that protrudes from an inner circumferential surface of the circumferential wall of the housing toward a part of an outer circumferential surface of the stator core, wherein the part is located on a side of the other of the axially end portions of the stator core.
