IMPREGNATED RESIN FOR LIFTING MAGNET, LIFTING MAGNET, AND METHOD OF MANUFACTURING LIFTING MAGNET

摘要

PROBLEM TO BE SOLVED: To provide an impregnated resin for a lifting magnet containing a filler material which exhibits an excellent heat dissipation property and an excellent filling property, to provide a lifting magnet with the impregnated resin, and to provide a method of manufacturing the same.;SOLUTION: The lifting magnet accommodates a coil 3 in a metal case 2, which is constituted of a top plate 21, a bottom plate 22, a side plate 23, and a spool 24. The impregnated resin 4 filled in the case 2 while accommodating the coil 3 is impregnated into the whole of the case 2 including gaps of the coil 3, wherein the impregnated resin 4 contains the resin material and the filler material mixed by the resin material, a rate of the filler material occupied in the impregnated resin is ≥40 wt.% and ≤65 wt.%, and thermal conductivity of the impregnated resin is ≥0.4 W/(m×K) and ≤0.56 W/(m×K).;COPYRIGHT: (C)2010,JPO&INPIT
