摘要： Integrated devices and methods for compensating electric grade steel lamination stack height for use in a conventional two-plate high pressure die cast tool used for casting aluminum induction rotors. These devices and methods allow for significant variation in the lamination stack height without associated failures related to stack height variation, and also ensure constant and accurate clamping pressure on both the OD and ID of the steel lamination stack which prevents electric insulation damage, metal flow between laminations, large casting metal flash, and tool damage for excessive height laminations stacks. The clamping pressure is adjustable and is actuated from a single hydraulic cylinder which allows for a wide range of pressures to accommodate fine adjustment of clamping pressure to insure no damage occurs to the laminations.

摘要： A rotor casting includes a lamination stack and a cast structure including proximal and distal cast end rings respectively adjacent proximal and distal end faces of the lamination stack. Cast axial ribs are distributed radially on a peripheral surface of the lamination stack and extend between the proximal and distal cast end rings. Cast feed members extend axially from the proximal cast end ring and are respectively positioned radially between an adjacent pair of axial ribs. In one example, cast bar segments integral to the proximal and distal cast end rings are formed in axial slots of the lamination stack. In one example, a bar insert in each axial slot has insert ends that extend respectively from the proximal and distal end faces of the lamination stack and are fully encapsulated respectively in the proximal and distal cast end rings. A method of forming the rotor casting is provided.

摘要： In a setting step, a plurality of steel plates configuring a rotor core stacked in an axial direction of a rotor is set in a predetermined position in a mold that is capable of being opened and closed by relative movement in the axial direction. In a casting step, molten metal is fed into a molten metal introduction passage to form a conductive member of the rotor. The molten metal introduction passage has a ring-shaped gate that is opened so as to oppose one axial end surface of the steel plates set in the mold. In a cutoff step, the molten metal is cut off in the molten metal introduction passage so as to be separated into a gate side and a molten metal introduction opening side. In a mold-releasing step, the mold is opened such that a casting configuring the rotor is removed from the mold.

摘要： In a method for producing cast components for electrical applications, a hardenable aluminum alloy is melted and filled into a die casting mold. The melted aluminum alloy is cooled by the die casting mold that is comprised of a material that has a thermal conductivity causing the melted aluminium alloy to be cooled at a cooling rate of approximately ≧5×102 K/s. Prior to filling, the melted aluminum alloy is introduced into a fill chamber and the melted aluminum alloy is displaced at a minimal displacement speed within the fill chamber.

摘要： Ceramic adhesive is applied inside the slots of an electric machine squirrel cage rotor prior to casting or insertion of rotor conductors. This heat-resistant insulation provides superior electrical insulation that is also mechanically rugged, thus enabling casting of squirrel cage rotors by die or cost-effective consumable pattern casting. The consumable pattern cast copper rotors are electrically well insulated, thus minimizing rotor losses. The ceramic insulation in cast rotors enables longer conductors to be cast by thermally insulating the molten metal from the cooler laminations. The ceramic insulation in fabricated rotors withstands the high temperatures of end ring attachment. This method is applicable to both conventional induction machine rotors and brushless doubly-fed induction machine rotors and provides the degree of electrical isolation of the bars from the laminations needed to avoid excessive parasitic torques in doubly-fed machines, while ensuring adequate thermal conductivity to dissipate conductive bar heat to the laminations.
