Problems solved by technology

[0002] The heat generated by double-stator single-rotor disc motors is mainly composed of stator assembly iron loss and copper loss, rotor assembly iron loss and permanent magnet eddy current loss. At present, double-stator single-rotor axial flux motors mostly use end covers or The end face of the housing is equipped with a cooling water system to cool the stator. The cooling water system adopts the fixing method of end cover, cover plate and sealing ring, and some adopts the method of water channel integrated casting and housing, but there is no rotor cooling scheme.

Abstract

The invention discloses a motor cooling system, a motor and a vehicle. The motor cooling system comprises a cooling water channel and a cooling oil channel which are arranged in the motor, the motor comprises a shell, a rotor assembly and at least one stator assembly, the shell defines a containing cavity, the rotor assembly and the stator assembly are both arranged in the containing cavity, The rotor assembly comprises a rotor shaft and a rotor support, and the stator assembly is arranged on the rotor shaft in a sleeving mode and connected with the shell. The cooling water channel is arranged at the end of the shell, a water inlet and a water outlet are formed in the end of the shell, and at least one cooling water channel is arranged at one end of the shell. The cooling oil channel comprises an oil inlet channel, a plurality of oil guide channels and an oil outlet, the oil inlet channel is formed in the rotor shaft, the oil guide channels are arranged on the rotor support and distributed in a radial shape, one end of each oil guide channel is communicated with the oil inlet channel, the other end of each oil guide channel is open towards the stator assembly, and the oil outlet is formed in the side wall of the shell. The motor cooling system can improve the cooling efficiency and cooling effect of the stator assembly and the rotor assembly.
