The invention relates to a cooling system for a traction motor of a motor vehicle, at least comprising: a circuit system; a first circulation pump for conveying a first cooling fluid; a motor input interface fluidly connecting the circuit system on the input side to a first winding head region of the traction motor to be temperature-controlled; a motor output interface fluidly connecting the circuit system on the output side to a second winding head region of the traction motor to be temperature-controlled; and a heat exchanger for dissipating heat from and/or supplying heat to the first cooling fluid circulating in the circuit system, wherein the traction motor comprises a plurality of cooling slots arranged between the winding head regions for conducting the first cooling fluid. The main feature of the cooling system is a second exhaust line via which the highest points of the winding head regions are fluidically connected to each other in the normal orientation of the traction motor in the earth's gravitational field. The proposed cooling system can prevent gas inclusion from remaining in the hydraulic recess of the traction motor.

    本发明涉及机动车辆的牵引电机的冷却系统,至少包括:回路系统;输送第一冷却流体的第一循环泵;在输入侧将回路系统流体连接到要进行温度控制的牵引电机的第一绕组头区域的马达输入端接口;在输出侧将回路系统流体连接到要进行温度控制的牵引电机的第二绕组头区域的马达输出端接口;从在回路系统中循环的第一冷却流体散热以及/或者向该第一冷却流体供热的热交换器,其中牵引电机包括布置在绕组头区域之间用于引导第一冷却流体的多个冷却槽。冷却系统的主要特征是设有第二排气管线,在牵引电机在地球重力场中的正常取向下,绕组头区域各自最高点通过第二排气管线彼此流体连接。用所提出的冷却系统可以防止牵引电机的液压凹处中留有气体夹杂。
