An electric traction machine, a motor vehicle, and a method for controlling dissipated heat in the electrical power plant of the motor vehicle are described herein. The power plant is supplied with a current, where, in order to provide a predetermined amount of dissipated heat, a ratio between a field-forming and a torque-forming current deviating from an optimum ratio for a respective operating point of the power plant is prescribed. The predetermined dissipated heat is provided by a power plant embodied as a magnet-less three-phase alternator while a rotor current flowing through a rotor of the three-phase alternator is adjusted, the field-forming and the torque-forming currents being prescribed such that acoustic interference signals of the three-phase alternator are minimized by the ratio, and the rotor current is adjusted such that the predetermined dissipated heat is provided by a combination of the rotor current and the ratio minimizing the interference signals.
