ENAMEL WIRE, CONDUCTOR WIRE PROCESSING DIE AND APPARATUS AND METHOD FOR PRODUCTION OF ENAMEL WIRE USING THE DIE

摘要

PROBLEM TO BE SOLVED: To provide an enamel wire which is low-cost and is reduced in adverse effects due to split flaws of conductor wire and improved in adhesion between the conductor wire and the enamel coating and an apparatus and a method for production of an enamel wire which enables production of the enamel wire.SOLUTION: An enamel wire includes a conductor wire 1 and an enamel coating, and the conductor wire has a spiral groove 20 or two spiral grooves intersecting each other in the surface. The thickness of the enamel coating is 10 μm or greater; the depth of the groove(s) is 10-50 μm; and the pitch of the groove(s) is 50 μm or smaller.
