  • Patent number: 10256699
    Abstract: A method and device for liquid cooling of an electric motor and a transmission configuration. The electric motor includes a rotor with a rotor shaft and a stator provided with windings, and the transmission configuration includes a transmission shaft. The rotor and transmission configuration are journally supported by a support configuration. Supplying a liquid for cooling via the support configuration is performed in such a way that the electric motor as well as the transmission configuration are cooled.

  • Patent number: 9071087
    Abstract: The invention relates to an electric drive device (10; 110; 210; 310; 410) comprising an electric motor (20) with a stator (24) and a rotor (22) arranged to rotate a drive shaft (26), a housing (30; 130; 230; 330; 430) in which the electric motor (20) is housed, which housing has an essentially ring shaped cross section with an imaginary center axle (X), wherein the electric motor (20) is eccentrically arranged in the housing (30; 130; 230; 330; 430) in such a way that the rotational center of the drive shaft (26) of the electric motor (20) runs essentially parallel to and at a distance from the center axle of the housing (30; 130; 230; 330; 430) so as to form a desired space (36) between the electric motor and said housing. The invention also relates to motor vehicle with an electric drive device.
