ELECTROMAGNET DRIVING DEVICE Russian patent published in 2012 - IPC H01F7/13 H01F7/08 

FIELD: electricity.

SUBSTANCE: proposed electromagnet driving device comprises a circular multipolar electromagnet, an anchor fixed via elastic elements to a body, which is installed onto a support flange of an electromagnet stator, at the same time the anchor is rigidly connected with a working element in the form of a stem and is sealed with a membrane at the outlet from the body. In the electromagnet of the device at the inner and outer surface of electric winding coils arranged in slots of the cylindrical multipolar core there are two additional cylindrical cores, which are connected to each other and to the multipolar core with a common yoke, at the same time the space between additional cores together with coils is filled with a compound, and the electromagnet anchor is made of a strip of an electrotechnical steel in the form of a bobbin, the inner diameter of which corresponds to the inner diameter, and the outer one - to the outer diameter of the stator cores, and which is rigidly fixed in a location washer.

EFFECT: reduction of scattering flows and increased traction force.
