DEVICE FOR CONTROLLING AN ELECTRIC MOTOR WITH A PULSED CONTROL SIGNAL

摘要

The invention relates to a device for controlling an electric motor with a pulsed control signal, especially with a pulsed voltage signal or a pulsed current signal, said device comprising a switching element (105) for converting a constant signal into the pulsed control signal. The switching element (105) can be brought into a first switching state with a first resistance value and into a second switching state with a second resistance value. A control device (107, 117) is provided for bringing the switching element into a state with a third resistance value smaller than the second resistance value, as it is brought into the second switching state.
