Abstract: A mechanical interface for relieving stress between an outer layer and an inner insulating layer in a layered insulating tape structure surrounding an electrical conductor. The interface tape includes a porous non-woven carrier having opposing sides including a release region located at a first side and a non-release region located at an opposite second side. The release region is treated with a release material for substantially inhibiting adhesion between the first side and an adjacent outer surface. The non-release region is untreated by the release material for substantially facilitating adhesion between the second side and an adjacent inner surface.

Abstract: A heat tack application involves arranging an adhesive between a strand of conductive material and a strand of insulation material; applying a temperature of about 100-300° C. and a pressure of about 5-100 psi for about 5-120 seconds to tack the adhesive. A stack can thereby be formed, and a plurality of stacks assembled to form a nascent rotor coil that is subsequently arranged in a rotor slot. An applied temperature of about 100-500° C. and a pressure of about 100-1,500 psi can fully cure the adhesive after the coil is arranged within the rotor slot. Depending on the context of use, the conductive material may more generally be a first component, and the insulation material may more generally be a second component.

Abstract: Disclosed is an apparatus and method to build programs from activity function units (AFUs) within a graphical environment. Each AFU is made from graphical representations of functional units (FUs). The resulting AFUs can be locked so that users cannot view proprietary and trade secret information as to how they accomplish their tasks. AFUs can be combined with other FUs and previously-created code represented in FU form to build large complex programs which are modified and added to by the user by means of manipulation of graphical elements on the computer screen without disclosing underlying coding.

Abstract: A method is for making slot cell insulation 20 for positioning in a rotor slot between rotor windings 17 and adjacent portions of the rotor 16 of a dynamoelectric machine 15. The method may include providing a male mold 51 having an outer shape corresponding to the rotor slot, stacking a plurality of layers adjacent the male mold, and laminating the stacked layers together on the male mold to thereby form the slot cell insulation 29. The stacked layers may include a pair of aromatic polyamide layers 32a, 32b and a polyimide layer 33 therebetween. These layers may be prelaminated, that is, laminated together prior to the overall lamination of the layers. Each aromatic polyamide layer 32a, 32b may be NOMEX® 410 paper, for example. In addition, the polyimide layer 33 may be a corona-resistant polyimide layer, such as a KAPTON® CR layer.

Abstract: Disclosed is an apparatus and method to build activity sequenced engine programs from activity function units (AFUs) within a graphical environment. Each AFU is comprised of a set of graphical representations of functional units (FUs). AFUs can be combined with other FUs and previously-created code represented in FU form to build large complex programs which present the same functionality as iterative systems but are easily modified and added to by the user.

Abstract: A molded rotor block, as well as other molded articles of manufacture, are made from a resin material selected from the group consisting of epoxy thermosets, polyester thermosets, phenolic, and melamine; and a reinforcement material selected from the group consisting of glass and mineral filler. The article of manufacture is adapted to withstand temperatures that range from about −40° C. to about 180° C.−40° C. and to withstand centrifugal loading at about 1500 RPM to about 4500 RPM while functioning as an insulator. The molding operation provides many advantages over CNC machining and other manufacturing methods.

Abstract: An insulating material (10) for an electrical generator rotor and method of forming the same. An insulating substrate (12) is formed from a single layer of woven glass fabric (16) having a necessary thickness and coated with a thermosetting resin (18). A first side of the substrate (12) is adhered to a first layer of copper winding material (20) of an electrical generator. A second side of the substrate (12) is covered with a layer of contacting material (14), such as plastic film, paper, treated felt or coated glass fabric, to cover the rough as-formed surface of the substrate (12) resulting from the coating of the necessarily thick layer of fabric (16). The contacting material (14) provides a desired coefficient of friction to form a slip surface permitting relative movement between the first layer of copper winding material (20) and a second layer of copper winding material (24) disposed over the insulating material (10).

Abstract: An insulating material (10) and method of forming the same having an electrically insulating substrate (12) and a contacting layer (14) bonded to the substrate, the contacting layer having a predetermined coefficient of friction. The substrate may be an epoxy saturated fiberglass, and the contacting layer may be a polyester material such as PEN. The thickness of the insulating material is easily controlled without sanding and the contacting layer provides a surface with low coefficient of friction for use between adjacent layers of copper in the windings of an electrical generator.
