ABSTRACT:
A rotor which utilizes winding guide discs to enable the slots of any rotor to be completely filled with wire without thereby increasing the diameter of the rotor by bulging out of the end windings. Winding guide discs having substantially the same cross section as the rotor are spaced a sufficient distance from the ends of the rotor to contain that portion of the end windings which will fill the space between the outside diameter of the rotor shaft and the minimum radial dimension of the slots in the rotor. After this space is filled, further end windings are wound from the rotor slots about corresponding apertures in the winding guide discs within the corresponding space on the disc. In the event that this corresponding space is filled further winding guide discs may be used as required to prevent the bulging of the end windings sought to be avoided. In a preferred construction the rotor core may be eliminated and the winding may be accommodated on winding guide discs; spaced by a stepped shaft, or by an insulated sleeve providing double insulation. Additional winding guide discs may be used, as required, to accommodate the end windings without bulging. The rotor assembly thus constructed may be potted or molded in plastic to provide support for the windings against centrifugal force.
