ELECTROMAGNET Russian patent published in 2004 - IPC

Abstract RU 2224314 C1

FIELD: electrical engineering. SUBSTANCE: invention can find use in manufacture of forward-motion cylindrical electromagnets which are key components of hydraulic automatic devices. Proposed electromagnet includes body, coil, sleeve, mobile armature and antifriction films placed between armature and sleeve. Sleeve has circular groove into which bent edge of first antifriction film is inserted with fixation, second antifriction film is fixed by internal walls of sleeve. EFFECT: reduced manufacturing cost of electromagnet securing preset functional characteristics. 2 dwg
