Abstract

PURPOSE: To raise the reliability of electric and mechanical characteristics, by using a thixotropic thermosetting synthetic resin as a winding end insulator and setting the resin in a finger touch dry state at room temperature.
CONSTITUTION: Interlayer insulators 9 and insulators 1, 4, 11, all of which has a large width and extends over the ends of the winding, are used to insulate the layers from one another and from the ground. Each interlayer insulator 9 has an adhesive layer, which is made by coating a synthetic resin on at least one side and semi- cured, then temporarily softened by heating to have an adhesive property and thereafter completely cured. Since the end insulator 13 is a high-viscosity thixotropic synthetic resin varnish produced by mixing a single-liquid epoxy varnish with fine insulator powder of 1000 μ or less in grain size, the end insulator is set in a finger touch dry state has an adhesive property at room temperature and is hardened by heating.
