Abstract
A method for manufacturing an insulated coil for use in an electromotive machine includes an aligning and winding step for forming a coil by aligning and winding a wire coated with insulating material; an insulator forming step for winding or coating an insulator around a slot inserting portion of the coil which is formed in the aligning and winding step and applying an adhesive layer between the insulator and the slot inserting portion; and a shaping step for shaping and fixing the wire and the insulator of the slot inserting portion into a unit through melting by increasing the temperature thereof and thereafter cooling the adhesive layer of the slot inserting portion , around which the insulator is wound or coated and applying the adhesive layer therebetween in the insulator forming step, under a restrained condition using a shaping metal mold.
