  • POSITION DETECTION IN AN ELECTRIC DRIVE UNIT FOR CORDS OF BLINDS
    Publication number: 20210254402
    Abstract: Electric drive unit (104) for cords of blinds, comprising: a DC driven electric motor (106), a cord winding/unwinding unit (107) driven by the electric motor (106), for winding/unwinding one or more cords (102a) of a blind (103), a control circuitry (105) arranged for controlling the operation of the electric motor (106) by controlling the DC supply of the electric motor (106), the control circuitry (105) being functionally connected to one or more rotation detection sensors (108), each rotation detection sensor (108) being arranged for detecting increments of the rotation of the electric motor (106) by cooperating with a rotating element (109) driven by the electric motor (106), the rotating element (109) having at least two discrete elements (110), wherein the passage of which is detected as detection pulses by the one or more rotation detection sensor (108), characterized in that the control circuitry (105) is arranged for controlling the electric motor (106) dependent on the time development of the detec
