Abstract: A method of forming a fuel injector clamp utilizing powder metal techniques is provided. A powder metal charge comprising in percent by weight, 0.6-0.9 carbon, 1.5-3.9 copper, 93.2-97.9 iron with the balance other elements, is die compacted to a density of 7.0-7.1 grams per cubic centimeter pre-sintered at 1500-1600 degrees Fahrenheit to form a powder metal blank. The powder metal blank is then lubricated and re-compacted to at least 7.3 grams per cubic centimeter and sintered at 2050 degrees Fahrenheit to form a final powder metal blank. The fuel injector clamp itself is comprised of a unitary structure of powder metal having a generally cylindrical center portion, with a first wing portion extending laterally there from and a second wing portion extending laterally there from at a 180 degree angle from the first wing portion.

Abstract: A method of calculating the cost saving for producing a metallic component by the use of a powder metal process is provided. The method includes the steps of analyzing the current production method of the component, usually machining, to determine the current unit cost. The customer would agree to purchase an agreed supply of components for an agreed period of time. The production of the component utilizing powder metal process is then analyzed to determine the powder metal unit cost. The savings for production of the component utilizing the powder metal process is then presented to the customer. The customer would, then agree to purchase an agreed supply of components.

Abstract: A method of forming a crankshaft bushing or similar component is provided. A compaction die is provided having an axial, generally cylindrical internal opening. An upper and a lower punch are provided with exterior surfaces corresponding to the internal opening of the compaction die. An upper core rod passes through an axial opening in the upper punch. A lower core rod passes through an axial opening in the lower punch. The upper core rod and the lower core rod each may have a generally flat external surface section. A metal powder is compacted in the compaction die by the combined action of the upper and lower punches and the upper and lower core rods.

Abstract: The modular conical stator pole provides an improved conical stator assembly on electrical machines. The improved conical stator pole assembly comprises a plurality of stator poles, each pole comprising an assembly having a coil secured on a soft magnetic composites (SMC) stator pole tooth by inserting a winding support through the open core of the coil and attaching a back iron and a stator face to either end of the winding support. Each stator pole having a parallelogram shaped cross section for forming a conical shaped rotor space when the stator poles are assembled having the back irons bearing against each other to space the coils apart and form a conical shaped outside profile of the stator pole assembly. The conical stator having a small end and a big end. The tooth comprising a winding support integrally molded with either the back iron or the face.

Abstract: A method is provided for cold forming center web or webless tapered piston pins in one forming sequence. The method eliminates secondary operations such as but not limited to machining, annealing, coating and secondary forming. The method includes the steps of cutting a metal rod into a substantially cylindrical slug piece, die extruding the slug piece to form a first cavity in the slug piece, optionally die extruding the slug piece to form a second cavity in the slug piece, piercing the slug piece to form the slug piece into a hollow cylindrical piece, die extruding the hollow cylindrical piece at either end to form a hollow cylindrical piece having a taper on an internal surface of the hollow cylindrical piece at either end.

Abstract: A modular electric motor stator pole comprising a plurality of independent stator components stacked axially, each stator segment comprising a tooth tip, a back iron and a coil, the tooth tip comprising a stator face and a tooth body, the tooth body having a first end on the tooth tip, a winding support and a second end. The coil having a plurality of windings about an open core, the winding support extending through the open core. The back iron removably attached to the second end of the tooth body and adjacent stator segments are spaced by interfaced adjacent back iron. The modular stator pole assembled with a predetermined number of stator components wherein the design may be changed without retooling the manufacturing facility by adding or subtracting independent stator components from the stack and further the modular design allows replacement or assembly of components in the field.

Abstract: A compacted magnetic powder metal component assembly for use in an electrical machine is provided. Each component assembly has a top section and a bottom section. Each top section is comprised of a generally cylindrical center portion, a plurality of winding supports extending radially outward from the center portion and a core segment at a radial edge of each winding support. Each bottom section is comprised of a generally cylindrical center portion, a plurality of winding supports extending radially outward from the center portion, and a core segment in a radial edge of each winding segment support. The top section and the bottom section are combined to form the component assembly.

Abstract: A compacted magnetic powder metal component stator for use in an electrical machine is provided. Each stator is comprised of a plurality of stator core assemblies. Each stator core assembly forms an arcuate section of the stator core itself. Each stator core assembly is comprised of an inner shoe component, with winding guides supporting a winding, and at least one back piece and two end caps fitted to the winding on the outer radial edge of the stator assembly.
