Abstract
Methods and systems for cooling an electric motor are provided. An electric motor system, in one example, comprises a rotor with a plurality of axial air conduits, a first balancing plate positioned on a first axial side of the rotor, the first balancing plate comprising an inlet air duct and an outlet air duct, and a second balancing plate positioned on a second axial side of the rotor, the second balancing plate comprising an inlet air duct and an outlet air duct. In the electric motor system, the inlet air duct in the first balancing plate is radially offset from the inlet air duct in the second balancing plate.
