Load and fuse resistant electromagnet winding using an

Winding for stators or rotors of electric motors comprises an insulated wire (which may be insulated by one or more layers of polyester, polyesterimide, polyimide-amide, polyimidazole, polyimide or the like) which has a temperature of over 300 deg.C when short-circuited between two conductors that intersect at right angles, and which heats up at a rate of 2 to 3 deg.C/min when under 100 V a.c. and under a load of 200 g at the point of intersection, said winding being bonded in a mixture containing an epoxy resin (mol. wt >800) as main component and a curing agent that is not based on an acid anhydride. The binder does not swell or peel off at temps. below the softening temp. of the coating of the wire;.
