Abstract: An apparatus for electrically rotating a shutter's axis in order to fold and unfold the shutter includes an electrical motor; a gear that is driven by the motor; and a rotatable adapting unit or a flange to which the shutter's axis is connected. The rotatable adapting unit is connected to the gear. The apparatus may also include two switches, each switch stopping the motor when depressed, located at both ends of a rail, and wherein an element is installed in the rail capable to move along the rail and the element depresses one of the switches when arriving to any end of the rail. A circular plate with a spiral tunnel grooved on its surface is joined to the rotatable adapting unit or flange; and a pin is installed on the element and is settled in the grooved tunnel, moving the element along the rail according to the rotation of the plate.
