An actuation assembly in a double-glazing unit with a perimetric frame which supports two glass panes which form, between them, a sealed air space which accommodates a light blocking blind which is adapted to be orientated and/or moved from a fully packed or rolled-up condition to unfolded conditions and vice versa. The actuation assembly has a rotor which is arranged between the panes, is connected so as to rotate together with an actuation shaft of the light blocking blind, and is provided with one or more permanent magnets which are arranged with alternating polarities, and at least two electromagnets which are arranged so that when they are crossed by an electric current they generate respective magnetic fields whose polarities can vary according to the direction of the current and are arranged on corresponding angular positions with respect to the rotor.
