Abstract (en)
[origin: WO2016128902A1] A device (1) for driving a roll-up element comprises: a drive shaft (9); a winding roller (4), connected to the drive shaft (9) to rotate as one therewith about a longitudinal axis of rotation (A) and to move the roll-up element (2) in a movement direction, between a rolled-up configuration and an extended configuration; an electric motor (6), having a stator (6a) and a rotor (6b), wherein the rotor (6a) defines a transmission shaft (7) having a first and a second end; a reduction gear unit (8), having an input coupled to the first end of the transmission shaft (7) and an output connected to the drive shaft (9); an electromagnetic brake (10) connected to the second end of the transmission shaft (7) and movable between an active position, where it prevents the transmission shaft (7) from rotating, and a rest position, where it allows the transmission shaft (7) to rotate, wherein the electromagnetic brake (10) is in the rest position when it is electrically powered; a stator electrical circuit (20) of the stator (6a) connected to the electromagnetic brake (10) to be electrically powered in series therewith, by a primary electrical power supply, so that when the stator circuit (20) is powered, the electromagnetic brake (10) is also powered; an auxiliary power supply device (17), connected to the electromagnetic brake (10) at a node that is electrically interposed between the stator circuit (20) and the electromagnetic brake (10), for powering the electromagnetic brake (10) without powering the stator circuit (20).
