POLARIZED ELECTROMAGNETIC WITH PASSIVE STOCK RETENTION Russian patent published in 2017 - IPC H02K33/06 H02K33/16 

Abstract RU 2634424 C1

FIELD: electricity.

SUBSTANCE: electromagnet contains coaxially located control coils, annular permanent magnets, soft magnetic inserts. At least one control coil and soft magnetic inserts of the magnetic circuit are fixed to the inner part of the magnetic circuits. The anchor is made of annular permanent magnets with axial magnetization, the number of which is at least one more than the control coils with axial magnetization. The stock is mounted with the ability to freely move through the hole in the non-magnetic flange. The length of the soft magnetic insert of the anchor and the permanent magnet is approximately equal to the sum of the distance between the soft magnetic inserts of the magnetic circuit and the length of the soft magnetic insert of the magnetic circuit. The soft magnetic inserts of the anchor are located between the permanent magnets. The soft magnetic inserts of the magnetic circuit are located at the ends between the control coils. The permanent magnets are located with the same poles to each other.

EFFECT: fixing the stock in one of the end positions with a specified retention force without the cost of electrical energy.
