POLARIZED ELECTROMAGNET Russian patent published in 2020 - IPC H01H51/22 H01F7/122 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. In polarized electromagnet with serial magnetic circuit, rotary armature is made on one side "active", containing permanent magnet with pole tip, and on the other side – containing "passive" element with pole tip with possibility of simultaneous and coordinated use of attracting forces of pole tips of armature on the side without magnet, and repulsive forces of pole tips of armature from side with magnet. Pole tips are arranged equidistantly and parallel to the rotational axis located parallel to the winding located on the middle part of the H-shaped magnetic conductor, so that armature is pulled only to one of two sides of H-shaped magnetic conductor, pole armature tips contain their own rotation axes and are made with possibility of self-mounting on magnetic conductor poles in end positions, armature and magnetic conductor are connected with possibility of armature stroke magnitude adjustment.

EFFECT: wider field of use of a magnetic system of a polarized electromagnet with simultaneous universality of design for both double-stable design, and a single-stable polarized long-wave electromagnet with self-return.
