Claims
- 1. A simplified supplying system for potentiometers usable in an electronic memorization of position of a motor, said supplying system comprising:
- an electronic module; and
- an identification potentiometer for setting an adjusted position connected directly in parallel to terminals of said motor, said terminals of said motor being supplied with a first voltage that is variable and switchable between two reverse polarity states according to a rotation direction of said motor, wherein a reversal of one of said polarity states results in a reversal of voltage applied to said potentiometer, with said potentiometer having a slider that is connected via a first dividing bridge, which includes a first resistor connected to said slider of said potentiometer and a second resistor connected to a ground of a supplying system, to an input of an analog-digital converter that is subjected to a further reference voltage connected to said first voltage via a second dividing bridge, which includes a third resistor connected to said first voltage and a fourth resistor connected to a ground of a supplying system of said first voltage, with an output of said analog-digital converter being connected to said electronic module, and with a resistor value of said second and fourth resistors of said first and second dividing bridges being equal to a product of a resistor value of said respective first and third resistors multiplied by a same coefficient A.
