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.
Claims17
A method for liquid cooling of an electric motor and a transmission configuration, wherein the electric motor comprises a rotor with a rotor shaft and a stator provided with windings, and wherein the transmission configuration comprises a transmission shaft aligned with the rotor shaft in an axial direction, the method comprising:
- journally supporting the rotor and the transmission configuration by a support configuration, the support configuration having a main extension plane essentially perpendicular to the axial direction defined by the aligned shafts;
- and
- supplying a liquid for said cooling via said support configuration by applying the liquid from the support configuration directly onto the electric motor and the transmission configuration such that said electric motor as well as said transmission configuration are directly cooled.
A device for liquid cooling of an electric motor and a transmission configuration, wherein the electric motor comprises a rotor with a rotor shaft and a stator-provided with windings, and wherein the transmission configuration comprises a transmission shaft aligned with the rotor shaft in an axial direction, wherein the rotor and the transmission configuration are journally supported by a support configuration having a main extension plane essentially perpendicular to the axial direction defined by the aligned shafts, the device comprising at least one component configured to supply for said cooling via said support configuration by applying a liquid from the support configuration directly onto the electric motor and the transmission configuration such that said electric motor as well as said transmission configuration are directly cooled.
