摘要： Systems and methods for electric motor cooling. The cooling system, in one example, includes a sealing ring coupled to or formed in a stator and including a flange that axially extends outward from an axial side of the stator. The cooling system further includes a first sealing sleeve with a first sealing interface that is formed between the sealing sleeve and a motor housing and a second sealing interface that is formed between the sealing sleeve and the flange, where a cavity is formed between the sealing sleeve and the sealing ring in which a stator end winding is at least partially immersed in a coolant.

摘要： 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.
