摘要： A procedure for centrifugally casting a shorted structure around induction motor rotors is described. The method is commonly applied to a plurality of rotors disposed and arranged for rotational balance and supported on a suitable support, or optionally, on a plurality of supports arranged in layered fashion about a common rotational axis. The method comprises forming a wax representation of the shorted structure around a lamination stack; mounting a plurality of such lamination stacks in a mounting fixture and-attaching a suitable gating and runner system; forming an investment by coating the structure with refractory followed by melting out the wax; casting molten metal into the investment while it is rotating and aligning the mold to allow the centrifugal force generated to promote mold filling; and, continuing to rotate the investment until solidification is substantially complete.
