Abstract
A motor unit is provided having an electric motor, which is arranged in a housing, wherein the motor unit comprises a lubricant circuit, which cools and lubricates the electric motor, wherein the electric motor comprises a stator and a rotor, which is mounted rotatably in the stator, being connected fixed to the housing, while between the stator and the rotor there is a rotor gap. The motor unit further comprises a lubricant pump, which is fluidically connected to the stator housing, and a flow generating unit, which draws in air from the housing and blows the air into the rotor gap in order to remove lubricant from the rotor gap and reduce the internal friction in the electric motor. A method is also provided for reducing the internal friction in a motor unit.
