Abstract
The rotor body of an electrical machine has end windings supported by a plurality of circumferentially spaced rakes having tines between which the end windings pass in an arcuate pattern from and for return to an axial orientation within the rotor body. The rakes are supported on axial beams secured to the rotor body. An end disk is secured at the opposite ends of the beams and to a shield overlying the end windings. The rakes, beams and end disks provide axial end winding restraint. The end disk is weighted at selected circumferential locations to resist tendencies of the end windings to distort, e.g., toward an elliptical or non-concentric configuration about the rotor axis.
