The invention discloses an active cooling system and method for an automobile driving motor, cooling channels are respectively arranged between a motor stator, a motor rotor, the motor stator and a shell, the stator and the rotor are convenient to cool, a cooling water channel or an oil cooling channel and an oil pump do not need to be independently designed on the motor shell, the motor is miniaturized, the cost is low, and the cooling efficiency is high. The driving motor system adopting the direct cooling scheme reduces cost, increases efficiency, solves the problem of temperature limitation, and realizes improvement of a high-efficiency area of the driving motor; the continuous high-power working time is prolonged, an active heat management technology is adopted, the heat dissipation capability of the motor is improved, further miniaturization and light weight of the motor are facilitated, the cost is reduced, the normal working temperature of the direct cooling motor with active heat management is adjustable and controllable, and the performance in a high-temperature environment is improved.

    本发明公开了一种汽车驱动电机主动冷却系统及方法,在电机定子、电机转子、电机定子和壳体之间等分别设有冷却通道,便于定子、转子冷却,电机壳体上不需要单独设计冷却水道或油冷通道和油泵,电机小型化,低成本化,直冷方案的驱动电机系统,降本增效,解决温度限制问题,实现驱动电机高效区的提升;连续大功率工作时间的延长,主动热管理技术,提升电机散热能力,有利于电机进一步小型化和轻量化,降低成本,主动热管理的直冷电机,正常工作温度可调可控,提升了高温环境下的性能。
