Abstract: An electrical insulating system and an associated insulated stator bar are provided. The electrical insulating system includes an electrically insulating mica paper and a fiber glass disposed on a first surface of the electrically insulating mica paper. The electrically insulating mica paper and the fiber glass are impregnated with a curable binder resin composition. The curable binder resin composition includes about 21 weight percent to about 73 weight percent of a solid or semi-solid epoxy resin having an epoxide functionality of about 2.5, about 0.8 weight percent to about 49 weight percent of a liquid epoxy resin having an epoxide functionality of about 2, about 4 weight percent to about 15 weight percent of a bisphenol A-formaldehyde novolac, a metal acetylacetonate catalyst, and about 2.5 weight percent to about 15 weight percent of a toughener selected from the group consisting of polyethersulfone, methylmethacrylate butadiene styrene, and a combination thereof.

Abstract: A curable composition for an electrical machine is presented. The curable composition includes: (A) about 10 weight percent to about 30 weight percent of a polyfunctional cyanate ester; (B) about 25 weight percent to about 60 weight percent of a first difunctional cyanate ester, or a prepolymer thereof; (C) about 10 weight percent to about 30 weight percent of a second difunctional cyanate ester, or a prepolymer thereof, and (D) about 5 weight percent to about 25 weight percent of a thermally conductive filler comprising boron nitride. An associated method is also presented.

Abstract: A method of making a composite magnet wire includes mixing alumina nano particles with a polyimide polymer to form a polyimide mixture, the alumina nano particles having a surface treatment applied to outer surfaces of the alumina nano particles, the surface treatment including a phenyl-silane; coating a wire with the polyimide mixture by passing the wire through a coating die; heating the coated wire; cooling the coated wire; passing the coated wire through an annealing oven at a temperature of about 425° C. to about 475° C. at a speed of about 15 to about 30 feet per minute to anneal the coated wire; cooling the annealed coating wire; spooling the coated wire onto a metal spool; heating the spooled wire at about 300° C. to about 400° C. for about 20 to about 40 minutes; and cooling the heated spooled wire.
