ABSTRACT:
A high speed shaftless rotor construction is disclosed including a method of sequentially building up the rotor to facilitate disassembly for reworking and maintaining precise alignment of the reassembled elements. End turn supports are matched and preliminarily assembled with bolts to the core and the parts machined to achieve desired tolerances. After machining, the end turn supports are separated from the core, matched with end shaft fittings and additional machining carried out, after which the turn supports are separated from the end shaft fittings and reattached with the core. The shaft fittings are realigned with the assembled end support fittings and bolted into position after which final machining can be completed. All elements are then disassembled and the parts deburred and cleaned to eliminate any contamination prior to winding the field coil. After reassembly, winding of the field core and completion of the electrical connections, a cylindrical sleeve is disposed over the main core assembly and conventionally joined to effect a rigid structural rotor member capable of withstanding high speeds.
