A drive and control device for at least one commutator motor, a measurement device (consisting of a measurement element and a filter for identification of the commutator transitions) being connected to the supply lead of each commutator motor, downstream of which measurement device a counter for the commutator transitions is arranged which counter, for its part, is connected to a comparator for the actuating movement, which comparator has a required value input of a control device and whose output is connected to a switching mechanism for controlling the commutator motor. |
