A rotating electric machine includes a stator housed in a case, from which a power line is pulled out, and a temperature sensing element provided on the stator. The rotating electric machine includes a harness retainer that guides a wire harness that extends from the temperature sensing element, toward an inner circumferential wall of the case.

Rotating electric machine

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.

Vehicle electric motor

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.

A lubrication mechanism for supplying oil to a bearing of a vehicle electric motor that includes the bearing, a housing, a stator and a rotor having a rotor shaft rotatably held by the housing through the bearing. The housing defines an oil passage to which oil discharged from an oil pump is to be supplied. The oil passage and the bearing are located on respective opposite sides of a wall of the housing. The lubrication mechanism includes: a bolt hole passing through the wall; and a bolt engaged in the bolt hole.

Lubrication mechanism for bearing of vehicle electric motor

A rotating machine lubrication structure is applied to a rotating machine including a cylindrical stator, a rotor and a shaft. A resolver is disposed concentrically with the rotating machine center line between the bearing and the rotor in a direction of the rotating machine center line in the casing, the resolver includes an annular resolver stator fixed to an inner side surface of the casing in an outer circumferential portion of the resolver stator, and a resolver rotor disposed on an inner circumferential side of the resolver stator and fixed to and integrally rotated with the shaft, and the resolver stator is provided with an oil through-hole allowing the lubricating oil to flow through at a portion on an inner circumferential side relative to a part fixed to the casing.

Rotating machine lubrication structure

An oil pump for a vehicle includes a driven gear, a drive gear, a pump body, and a plate. The drive gear engages the driven gear. The pump body is secured to a rear cover of a transaxle case. The plate is interposed between the rear cover and the pump body. A pump chamber is formed between the rear cover and the pump body. The driven gear and the drive gear are housed in the pump chamber. The pump chamber is formed: between the plate and the pump body, or between the plate and the rear cover.
