摘要： The disclosure relates to the technical field of vehicle accessories, and specifically provides an electric motor for a vehicle and a vehicle. The disclosure aims to solve the problems existing in an existing electric motor for a vehicle that during spraying and cooling of an outer surface of an iron core, a heat dissipation area of the outer surface of the iron core is small, and a convective heat transfer coefficient of a heat dissipation surface is small. To this end, the electric motor for a vehicle according to the disclosure comprises a stator and an oil intake pipeline, wherein the stator comprises a plurality of first laminations, each of the first laminations is configured into the shape of a circular ring and is provided with oil passage holes, the plurality of first laminations are stacked in an axial direction of the first laminations, the plurality of stacked first laminations jointly enclose a cylindrical structure, the oil passage holes in the plurality of first laminations are in communication with each other to form cooling oil passages, and the oil intake pipeline is in communication with the cooling oil passages; and the cooling oil passages are arranged to enable the cooling oil to flow in an axial direction of the stator, and also enable the cooling oil to flow between a plurality of cooling oil passages in a radial direction of the stator, so as to improve a cooling effect inside the stator.

摘要： The disclosure relates to the technical field of vehicle accessories, and specifically provides an electric motor for a vehicle and a vehicle. The disclosure aims to solve the problems existing in an existing electric motor for a vehicle that during spraying and cooling of an outer surface of an iron core, a heat dissipation area of the outer surface of the iron core is small, and a cooling oil easily flows along an outer wall of a cooling oil ring, so that an end portion of a winding cannot be cooled. To this end, the electric motor for a vehicle according to the disclosure comprises a stator, cooling oil rings, and an oil intake pipeline, wherein the cooling oil rings are fixedly connected to the stator; each of the cooling oil rings is a hollow column with a circular ring-shaped cross-section, a side wall of the hollow column is provided with a cooling oil inlet and a plurality of oil spray holes, and an inner side wall of the hollow column is further provided with an oil guide rib; the stator comprises a plurality of first laminations, each of the first laminations is provided with oil passage holes, the plurality of first laminations are stacked in an axial direction of the first laminations, the oil passage holes in the plurality of first laminations are in communication with one another to form cooling oil passages, and the oil intake pipeline is in communication with the cooling oil passages, to improve the cooling effect of the electric motor.
