Abstract
A system and method for enhanced magnet wire insulation is described. The method comprises a sequence of operations to create an enhanced magnet wire insulation suitable for use in temperatures of about 550° Fahrenheit. A magnet copper wire is wrapped with a polyimide wrap and subsequently wrapped with an organic polymer thermoplastic (e.g., PEEK). The polyimide wrap is applied while the magnet copper wire is around a spool to create a wrapped magnet wire. The wrapped magnet wire can be heated using an induction coil in a metal tube bolted to an extruder to remove moisture and to enable adding the layer of organic polymer thermoplastic. The metal tube can be held at a partial vacuum to augment moisture removal of the wrapped magnet wire prior to running the wrapped magnet wire through the extruder which adds the organic polymer thermoplastic layer. This method produces an enhanced magnet wire suitable for a wide range of temperatures.
