Abstract: An electric machine includes a rotor assembly having a rotor core that extends in an axial direction and a stator assembly surrounding and coaxial with the rotor assembly. The stator assembly includes a stator core having slots extending in a radial direction into an inner surface of the stator core and extending axially from a first end surface to a second end surface of the stator core. The stator assembly includes stator coil windings disposed within the respective slots of the stator core and a first electrically insulating conformal coating disposed between the stator core and the stator coil windings. The conformal coating includes a polymer matrix impregnated with an effective amount of thermally conductive ceramic materials, above a percolation threshold, that form continuous thermal pathways across a thickness of the first coating.

Abstract: A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.

Abstract: A method of forming a coating on a component of an electrical machine is presented. The method includes coating a surface of the component with a ceramic material, via an electrophoretic process, to form a first coating. The method further includes contacting the first coating deposited by the electrophoretic process with a polymeric material to form a second coating. The method furthermore includes curing or melting the polymeric material in the second coating to form the coating including the ceramic material dispersed in a polymer matrix.

Abstract: An insulative assembly includes an insulative mica-based carrier film and first and second resistive grading layers joined to opposite sides of the mica-based carrier film. The first resistive material layer is configured to engage one or more conductors and insulate the one or more conductors from at least one other conductor. A method for creating an insulative assembly for one or more conductors includes obtaining an insulative mica-based carrier film, depositing a first resistive grading layer on a first side of the mica-based carrier film, and depositing a second resistive grading layer on an opposite, second first side of the mica-based carrier film.
