ELECTROMAGNET DRIVING DEVICE Russian patent published in 2010 - IPC H01F7/13 

FIELD: electric engineering.

SUBSTANCE: device comprises annular electromagnet, in the centre of which there is an elastic element installed, rigidly fixed with its one end on stator of electromagnet, and with the other one - on its anchor. Stator of electromagnet is arranged as per shielded type, as a single part from strips of electrotechnical steel in the form of two cylindrical cores arranged one in the other one with gap, where coil of electric winding is installed, and yoke rigidly fixed in flange. At the same time inner diametre of central core is arranged as more than diametre of elastic element. Anchor may be arranged from two cylindrical bobbins, which are installed with gap and rigidly fixed on orifice. Or arranged in the form of bobbin, inner diametre of which corresponds to inner diametre of stator, and outer diametre corresponds to outer diametre of stator, and which is also rigidly fixed in orifice. Device may be equipped with the second annular electromagnet and support slab, moreover, annular electromagnets are installed symmetrically on both sides of support slab.

EFFECT: reduction of power inputs and labour intensiveness of its manufacturing.
