VERFAHREN ZUR BILDUNG EINER SPULE UND NACH DIESEM HERGESTELLTE SPULENANORDNUNG

摘要

In a method for forming a coil and a coil formed by the method, a first wire having a thick insulating coating is inserted into a hole of a workpiece and wound around a peripheral surface of the workpiece to form a first winding layer, and a second wire having a thin insulating coating is continuously wound around the first wire to form a second winding layer so that a coil apparatus is formed. A junction between the ends of the first wire and the second wire serves as an intermediate tap for the coil apparatus.
