Abstract Due to their high power density and their high level of efficiency, permanent magnet synchronous motors (PMSM) are particularly advantageous as a traction motor in battery- electric sports cars [1]. The low but unavoidable power losses operate like internal heat sources and lead to a heating of the motor. Short-term overloads are possible, but cause the component temperatures to quickly rise. As a consequence of permanently high loads, for example when driving on a race track, components can reach critical temperatures. In this case, the power of the motor must be reduced in order to avoid irreversible damage of the motor. The critical components in PMSMs are the windings and the permanent magnets.
