ROTARY-SEGMENT ELECTROMECHANICAL SYSTEM WITH RELUCTANCE BOOST

The present invention relates to an rotary-segment electromechanical system and an electrical switching device comprising the same, which is capable of performing a direct rotating motion limited by a rotation angle of up to 45°, offering hereby a torque performance suitable for contact systems of electromechanical relays. The electromechanical system includes a pair of pole members having respective first end portions arranged outside respective first and second coils and a rotation member arranged between the pole members. The rotating member has a pair of lobes which can rotate around a central axis aligned along the intersection of a plane parallel to the first end portions with a plane transverse to the first coil axis under magnetic actuation exerted by the pole members. The pole members and rotating member are constructed with a reluctance-boost shape contour which enhances the actuating magnetic force onto the rotating member.
