Abstract:
1. Operating device ( 1 , 100 , 200 ) comprising means ( 2 ) suited to move at least one support ( 3 ) with an alternating motion (A) around a first axis ( 4 ), wherein said means ( 2 ) comprise one or more permanent magnets ( 5 ) arranged along at least one section of a circumference that is concentric with said axis ( 4 ) and at least one winding ( 6 ), said at least one winding ( 6 ) being controlled by a control unit ( 7 ) wherein said control unit ( 7 ) properly varies the voltage and/or current in said at least one winding ( 6 ) in order to vary the direction of motion of said at least one support ( 3 ) wherein said at least one support is integral either with said at least one winding ( 6 ) or with said one or more permanent magnets ( 5 ) characterized in that said at least one support ( 3 ) is arrangeable around a rotating pin ( 10 ), wherein said first axis ( 4 ) and the axis ( 11 ) of said pin ( 10 ) are parallel to each other and coincident, and wherein said pin ( 10 ) is set rotating by separate power means ( 12 ) and is able to rotate independently from said at least one support ( 3 ); in that said device also comprises means ( 9 ) suited to record the rotation speed of said rotating pin ( 10 ) and cooperating with said control unit ( 7 ), and in that said control unit ( 7 ) controls said means ( 2 ) suited to move said at least one support ( 3 ) in such a way as to maintain a relative speed equal to zero between said at least one support ( 3 ) and said rotating pin ( 10 ) for a given interval of time and/or a given angle (B).
