METHOD AND DEVICE FOR OPERATING AT LEAST TWO ELECTRIC MOTORS

The invention relates to a device and method for operating at least two electric motors (10, 12), which are subjected to the action of pulse-width modulated signals (18, 20) by means of a common control circuit (30) via a respective output stage (14, 16). Both signals (18, 20) are produced in a resp...

Beschreibung
Zusammenfassung:	The invention relates to a device and method for operating at least two electric motors (10, 12), which are subjected to the action of pulse-width modulated signals (18, 20) by means of a common control circuit (30) via a respective output stage (14, 16). Both signals (18, 20) are produced in a respective time difference with regard to one another. The invention provides that in the occurrence of a switching flank (40) of a signal (18 or 20) for one of the electric motors (10 or 12), the respective other signal (20 or 18) for the respective other electric motor (12 or 10) has either a low or a high value.
