Abstract
Systems are provided for an electric motor. In one example, a rotor assembly of the electric motor includes a shaft, a lubricant distributor inserted into the shaft, the lubricant distributor comprising a first section comprising a plurality of first nozzles and a second section comprising a plurality of second nozzles, the lubricant distributor further comprising an overflow portion arranged between the first and second sections, and a stationary lance positioned adjacent to the first section of the lubricant distributor, the lance comprising a plurality of radial nozzles. The rotor assembly controls coolant flow towards the rotor and bearings, helping to decrease drag losses.
