Abstract

Electromagnetic ultraswift actuator without springs including a movable part (1) and a statoric element (7) coaxial to the movable part (1), being the movable part (1) free to axially move inside the statoric element (7) , a permanent magnet (5) having its magnetic poles (6) following each other along the longitudinal axis of the movable part (1), being the movable part (1) kept in a provided position through the magnetic field generated by the permanent magnet (5) and suitable stroke limiters (2, 3, 12, 13, 14, 16), and a statoric winding (9) coaxial to the permanent magnet (5) and excitable so that it interacts with the permanent magnet (5) magnetic field, characterized in that the magnetic field generated in the winding (9) excites the statoric part (7) polarizing it so that the permanent magnet (5) reacts together with the movable part (1) connected to it moving towards another provided position, so that the axial translation of the permanent magnet (5) and consequently of the movable part (1) is respectively caused: in one direction, just by spontaneous attraction (active magnet/passive ferromagnetic circuit) eventually reinforced through an auxiliary electromagnetic excitation. in the opposite direction, substantially by repulsion between polarities (active magnet/ active electromagnetic circuit) having the same sign. <IMAGE>
