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.
