INSULATION STRUCTURE OF COIL FOR ROTARY ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To satisfy a need for higher heat resistance incident to reduction in size and enhancement in the reliability of a rotary electric machine. SOLUTION: Heat resistance can be enhanced even for a coil of an intricate shape or a high voltage coil by such an insulation structure for the coil a of rotary electric machine as impregnated with epoxy denatured polyester imide resin or epoxy denatured polyester imide resin added with a predetermined amount of epoxy acrylate and employing a wire affinitive to these resins selectively.
