The invention provides an electric drive assembly cooling and lubricating system and method and an electric motor.The electric drive assembly cooling and lubricating system comprises a first mechanical gear pump, a second mechanical gear pump, an electric three-way proportional valve, an oil storage cavity, a heat exchanger and a differential gear; the first mechanical gear pump part is coaxial and concentric with a motor shaft of the electric drive assembly; the second mechanical gear pump is coaxial and concentric with a gear shaft of the differential gear; the oil storage cavity is communicated with a first valve port of the electric three-way proportional valve through an oil pipe, the first mechanical gear pump is communicated with a second valve port of the electric three-way proportional valve, the second mechanical gear pump is communicated with a third valve port of the electric three-way proportional valve, and the first mechanical gear pump and the second mechanical gear pump are communicated with the heat exchanger. On the premise that an electric oil pump, a motor cooling water jacket and other components do not need to be independently arranged, cooling and lubricating of the electric drive assembly are achieved. Compared with the prior art, the embodiment of the invention has the advantages of simple structure and compact space.
