ELECTROMAGNET PULSE MECHANISM Russian patent published in 2013 - IPC E21C37/18 B25D13/00 

FIELD: mining.

SUBSTANCE: electromagnet pulse mechanism comprises a body of a ferromagnetic material, an anchor with rings from a non-magnetic current-conducting material, an induction coil, rear and front covers and a source of pulse current. The anchor is made of two hollow parts of identical length that are symmetrically arranged relative to the induction coil, between which there is a fixed ferromagnetic core, each part of the anchor comprises a ferromagnetic base and a non-magnet current-conducting ring placed on it. Such design of the anchor in the pulse mechanism provides for simultaneous power effect at its both parts and accordingly compensation of reaction forces acting at the coil and the body.

EFFECT: invention makes it possible to reduce vibration effect at a machine body at the side of a coil and to increase mechanism reliability.
