Abstract
The invention relates to a method for determining a rotor temperature of an electric motor, in particular an asynchronous motor, the rotor temperature being determined at least in accordance with reactive powers and/or in accordance with losses of the electric motor. A first rotor temperature is determined in accordance with the reactive powers and, depending on an operating range of the electric motor, plausibility-checked or replaced by a second rotor temperature, which is determined in accordance with the losses.
