| PURPOSE: To manufacture a die-cast cage rotor wherein it does not cause an increase in manufacturing costs and it is provided with an optimum axial- direction length complying with different output specifications. CONSTITUTION: A rotor core 40 which is provided with a shorter axial-direction length, balancing-ring members 28 which are arranged on both edges in the axial direction of the rotor core 40 and a spacer 42 which is provided with a thickness equal to the difference in the axial-direction length of the rotor core and which is arranged between the balancing-ring member 28 on one side and a lid member 22 for a stacking jig 12 are restrained and held at a stacked state by the stacking jig 12 which can restrain and hold the rotor core provided with a prescribed axial-direction length in a stacked state. Then, the rotor core 40 which has been restrained and held by the stacking jig 12, the balancing- ring members 28 and the spacer 42 are housed in a die-casting metal mold 14 which can mold a conductor part integrally with the rotor core which has been restrained and held by the stacking jig 12 and whose length is prescribed. In this state, molten aluminum is injected into slot holes 32 in the rotor core 40 and into ring-shaped spaces 30. COPYRIGHT: (C)1994,JPO&Japio | ||||||

| PURPOSE:To make the melt flow of a molten conductive material in one direction and produce a cast rotor of good quality by mounting conductive material pieces at the inlet of the spaces forming slot bars opposing to sprues. CONSTITUTION:The molten conductive material teemed through sprues 8 flows rectilinear toward slot bars 9a opposing to the vanes 7a of a sprue side end ring mold 1a but the rectilinear speed is decelerated at a certain degree by the mounted conductive materials 12. As a result, the molten conductive material fills the space parts of the end ring 6a on the sprue side, after which it advances toward an upper mold 3 by passing through the respective slot bars 9a, 9b, and forms the end ring 6b and vanes 7b on the counter sprue side. Hence, the melt flow the molten conductive material is made in one direction and uniformalized, whereby the joining of the flow in the slot bars 9 and the inclusion of air are obviated. The air in the bars 9 is escaped by the vents provided at the final arrival points of the molten material. | ||||||

| A method of forming a component having an internal passage defined therein includes forming a precursor core having a shape corresponding to a shape of the internal passage, and forming a hollow structure around the precursor core. The method also includes removing the precursor core from within the hollow structure, and disposing an inner core within the hollow structure to form a jacketed core. The method further includes positioning the jacketed core with respect to a mold, and introducing a component material in a molten state into a cavity of the mold, such that the component material in the molten state at least partially absorbs the hollow structure from a portion of the jacketed core within the cavity. Additionally, the method includes cooling the component material in the cavity to form the component. The inner core defines the internal passage within the component. | ||||||

| 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. | ||||||

According to certain embodiments, the first and second end plates may be assembled with first and second molds and a rotor core to form a casting assembly. A liquid casting material may be injected into the casting assembly, wherein the liquid casting material may solidify within one or more core passageways of the rotor core, thereby forming the conductors of the induction cage. The first and second end plates may also include flow channels that may be configured to facilitate the flow of the liquid casting material in the casting assembly, and increase the area of contact between the liquid casting material, when solidified, and the end plates. | ||||||
