STEP ELECTRIC DRIVE WITH FEEDBACK Russian patent published in 2015 - IPC H02P8/02 H02P8/42 

FIELD: electricity.

SUBSTANCE: electric drive contains an electric motor, a reduction gearbox, for example, consisting of worm couple, in which the worm is connected to an electric motor axis, and the worm wheel is fixed on an axis one end of which is power one and opposite - signal one on which the start-stop mechanism is located which consists of the flat metal screen from magnetosoft material which is placed on the information axis and has a circle shape. The line of the circle diameter has a cut. From one side of the cut the permanent magnet is placed, and from opposite side, the reed contact is located. Electric leads of DC electric motor and reed contacts are connected by two-wire lines with the control unit which is located at a distance from the electric drive. Two outputs of the control unit are connected to the RS trigger S-input, with the output connected to the power key connected to DC power supply. Electric leads of the electric motor are connected to outputs of the power key, and electric leads of the reed contact - to the control unit.

EFFECT: improvement of reliability and possibility to operate the electric drive both in step, and in continuous mode.
