METHOD AND DEVICE FOR CONTROLLING AN ELECTRIC MOTOR

摘要

The invention relates to a method and a device for controlling an electric motor by means of pulse-width modulated control signals. Control pulses having a target pulse duty cycle and pulse widths and pulse spacing varying over time are generated, wherein the pulse widths and pulse spacing varying over time are selected as a function of a load and/or thermal load of the electric motor and/or the control device thereof.
