The invention relates to a cooling system for a traction motor of a motor vehicle, comprising at least: a circuit system for conveying a circulating first cooling fluid; a first circulation pump for conveying a first cooling fluid in the circuit system; a motor input interface for 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 for fluidly connecting the circuit system on the output side to a second winding head region of the traction motor to be temperature-controlled; a first heat exchanger for dissipating heat from and/or supplying heat to a first cooling fluid circulating in the circuit system. The cooling system is characterized in particular in that a bypass line is provided, by means of which the first heat exchanger is directly fluidically connected to one another via at least one connection and the second winding head region via another connection. With the proposed cooling system, the traction motor can be effectively adjusted to a desired operating temperature.

    本发明涉及一种用于机动车辆的牵引电机的冷却系统,包括至少:用于输送循环的第一冷却流体的回路系统;用于在回路系统中输送第一冷却流体的第一循环泵;用于在输入侧将回路系统流体地连接到要进行温度控制的牵引电机的第一绕组头区的马达输入端接口;用于在输出侧将回路系统流体地连接到要进行温度控制的牵引电机的第二绕组头区的马达输出端接口;用于从在回路系统中循环的第一冷却流体散热和/或向所述第一冷却流体供热的第一热交换器。冷却系统的特征尤其在于,提供旁路管线,借助旁路管线,第一热交换器经由至少一个连接部并且第二绕组头区经由另一连接部彼此直接流体地连接。利用所提出的冷却系统,牵引电机可有效地调节到期望的操作温度。
