Abstract

The invention relates to a control part for a starting circuit of a direct-current electric motor, comprising a variable resistor by means of which a starting voltage of the direct-current electric motor can be set, wherein the variable resistor can be controlled by means of a control voltage, wherein the control part comprises a frequency filter, the output signal of which forms the control voltage and is provided in such a manner that the variable resistor is activated with time delay. The invention further relates to a starting circuit for a direct-current electric motor comprising a control part according to the invention. The invention further relates to an adjustment device comprising a direct-current electric motor, and to a starting circuit comprising a control part according to the invention.

Description

technical field [0001] The invention relates to a control unit for a starting circuit of a direct current motor, the control unit having a variable resistance with which the starting voltage of the direct current motor can be set, wherein the variable resistance can be controlled by means of control voltage to control. Furthermore, the invention relates to a starting circuit for a DC motor with the control unit according to the invention. Furthermore, the invention relates to a regulating device having a direct-current motor and a starting circuit provided with the control unit according to the invention. Background technique [0002] Electric motors, especially small electric motors such as adjustment drives for adjusting windows, seats or sun roofs, in particular in motor vehicles, are often switched on or reversed polarity directly via switches and / or relays. [0003] Figure 1(a) shows such a prior art circuit. To switch on and / or reverse the polarity of the electric m...
