Abstract

A method and a device for controlling an electric motor using pulse-width modulated control signals. Control pulses having a setpoint duty factor and temporally varying pulse widths and pulse spacing are generated in the process, the temporally varying pulse widths and pulse spacing being selected as a function of a load and/or thermal loading of the electric motor and/or its control device.
