Abstract: Method for operating a DC motor, where the DC motor is supplied with a variable DC voltage via a bridge circuit from a supply voltage and formed by a first, a second, a third and a fourth controllable switch, wherein the DC voltage is varied by pulse width modulation of the control signals driving the controllable switches of the bridge circuit. A control arrangement drives the bridge circuit by pulse width modulation, after the first switch connecting the DC motor to the supply voltage has been switched off, switches on the second switch connected to a ground terminal, or vice versa. The control arrangement automatically inserts a drive pause between the first or second switch being switched off and the second or first switch being switched on, whereby a bridge circuit voltage present at the DC motor is limited by a resultant maximum settable duty cycle to a maximum value.
