ELECTROMAGNET Russian patent published in 2007 - IPC H01F7/122 

FIELD: electric engineering, possible use for manufacturing electromagnetic neutral relays.

SUBSTANCE: electromagnet contains cores with windings, mounted in parallel on base, aforementioned cores also having L-shaped polar tips, separated from each other by non-magnetic gap, and also symmetric rotary anchor, cores with windings and L-shaped polar tips being combined in modules, consisting of several cores with windings and polar tips, mounted on base one below other. In each module windings of cores are connected with possible addition of magnetic flows created by them in cores, while part of every polar tip is positioned in gap between two adjacent parallel mounted modules in parallel to axis of core with possible interaction with part of symmetric rotary anchor mounted also between modules, located on one side of symmetric rotary anchor axis, perpendicular to axis of cores, while parts of polar tips of cores of two adjacent modules, positioned between these modules, are directed towards each other, and in first and last module cores are magnetically connected.

EFFECT: decreased dimensions and weight, decreased overheating of windings, increased working force.
