Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rapid, controllable, and affordable method of manufacturing field coil winding assemblies that enhances the mechanical integrity with reduced risks of turn shorts and turn migration.SOLUTION: A method for manufacturing a field coil winding assembly 100 includes cleaning a plurality of copper coils 106, forming a copper oxide layer by oxidizing each of the copper coils 106 in a solution, and rinsing and drying it. After the drying, a turn insulation system 108 including a turn insulation and an adhesive is attached to each of the copper coils 106. The turn insulation includes at least one of a glass fiber re-enforced novolac epoxy, a glass fiber re-enforced polyamideimide, a glass fiber re-enforced polyester, and a glass fiber re-enforced high temperature epoxy. After the attachment, they are cured and stacked in rotor slots 104.
