Rotary-Segment Electromechanical System with Reluctance Boost

An electromechanical system for an electrical switching device includes an energizing coil assembly having a first coil and a second coil each generating a magnetic field in response to an energizing current and a magnetic system providing a magnetic flux path passing along a plurality of magnetic flux lines of the magnetic field generated by the energizing coil assembly. The magnetic system includes a first pole member arranged on an upper side of the first coil, a second pole member arranged on an upper side of the second coil, and a rotation member arranged between the first pole member and the second pole member. The rotation member has a first lobe and a second lobe executing a rotation motion around a central axis. Magnetic field lines generated by the coils are directed toward the lobes and produce a resultant magnetic force that rotates the lobes toward the pole members.
