Abstract

An electric machine (14, 16) for a drive train (12) of a motor vehicle (10) has a coil arrangement and a rotor mounted rotatably relative to the coil arrangement. A fluid line is connected thermally to at least one component of the electric machine (14,16) to supply a cooling fluid (36) to the electric machine (14, 16) and to cool the at least one component. A fan (30, 32) is designed to supply cooling air (42) to the electric machine for cooling the electric machine (14, 16), and a control unit (34) controls the fan (30, 32). The control unit (34) controls the fan arrangement (30, 32) and the cooling air supply depending on a speed (n) and/or a torque (M) of the electric machine (14, 16).
