MULTIMODULE QUICK-OPERATING POLARISED TWO-POSITION ELECTROMAGNET WITH CLAPPER Russian patent published in 2008 - IPC H01F7/14 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electric engineering. Each electromagnet module contains magnetic conductor with sharply defined poles and non-magnetic flanges, control windings and four-pole anchor with sharply defined poles, which anchor is rigidly connected with torsion spring which is attached to one non-magnetic flange of magnetic conductor and is freely passing through the other flange, and is installed with possibility to turn in interpolar space of magnetic conductor. Magnetic conductor consists of two plates, non-magnetic spacer sleeves and constant magnets installed between plates of magnetic conductor at that in the plates of magnetic conductor and in non-magnetic spacer sleeves mounting holes are made. Four-pole anchor is made with magnetic shunts in the form of projections, all modules are joined by means of rigid fixing of four-pole anchors on common torsion spring.

EFFECT: power consumption decrease, providing of predefined operation speed and travel speed of moving element when overall size of electromagnet is limited in one of the dimensions.
