A circuit configuration for operating an electric motor is described, the circuit configuration containing a timer. As a function of a first differential signal between a setpoint signal and an actual value signal, a regulator supplies a first switch signal for feeding current to the electric motor. Simultaneously, the timer is started which limits the current feed signal to a specified maximum time. A detection system detects a change in the setpoint signal and thereupon outputs a second switch signal that also starts the timer and is able to trigger the current feed to the electric motor. The circuit configuration both protects the electric motor from a thermal overload and also makes it possible to feed current to the electric motor if a setpoint changes. The circuit configuration is suitable to be used in a variable speed drive.
