Abstract

An apparatus for temperature-dependent control of an electric motor includes a control device for adjusting the power output of the electric motor, and means for detecting the temperature of a component of the electric motor, wherein the control device reduces the power of the electric motor in the case of a component temperature above a temperature threshold, and wherein the temperature detection means distinguish between self-heating and external heating, wherein the control device counteracts only the self-heating by reducing the power.
