Abstract
A method for controlling an electric motor including a mechanical commutator, includes determining points in time at which commutation takes place by a sensor or without a sensor. The method further includes controlling the electric motor by a supply voltage signal having a sequence of pulses. The method further includes modulating the supply voltage signal by a modulation signal to reduce the magnitude of the supply voltage signal at the commutation points in time.
