POLARIZED ELECTROMAGNET Russian patent published in 2019 - IPC H01F7/122 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to electrical apparatus and can be used in designing contactors, polarized relays, remote switches and other automation devices. Polarized electromagnet comprises magnetic conductor made of two parallel cores with coils, armature, mechanically connected with return spring, at least, one permanent magnet arranged between cores of magnetic conductor and having direction of magnetization axis from one core to another. Fixed magnetic shunt is located above the permanent magnet coaxially with it and is rigidly connected to a traction rod installed with a possibility of back-and-forth movement in the fixed holder with a crank shaft, axis of rotation of which is perpendicular to direction of shunt with traction rod movement. Eccentric neck of crank shaft is arranged in cylindrical hole of traction rod. Eccentricity of the crank shaft neck is equal to the displacement distance of the magnetic shunt from the initial upper position to the lower position.

EFFECT: technical result is faster operation and reliability of device, as well as wider range of control devices automation devices.
