ABSTRACT:
A device and a method are provided for determining the after-run voltage of a direct current motor which is operated via cycled control. In normal operation the direct current motor is controlled via PWM control and a first specifiable pulse
o-pulse ratio. An evaluation unit is provided for determining an after-run voltage variable which is representative of the after-run voltage of the motor. Furthermore, for determining the after-run voltage variable the direct current motor is controlled via a specifiable, variable second pulse
o-pulse ratio.
