1. A rotor for an electromechanical device including a cylindrical core formed with lengthwise exterior slots, said slots having a least radial dimension, electrically conductive wire wound in said slots, said electrically conductive wire forming end windings at the ends of said cylindrical core by progressing from one slot to another slot separated therefrom by at least one intervening slot, at least one winding guide disc arranged in axially spaced relation beyond each of the ends of said cylindrical core, each of said discs having substantially the same circular dimensions as said cylindrical core and having a plurality of circumferentially open apertures equal in number and substantially aligned with said slots, a portion of said end windings being accommodated in the space between said cylindrical core and said winding guide discs up to no more than said least radial dimension of said slots, a remaining portion of said end windings being accommodated at the opposite end of said winding guide discs from said cylindrical core by passing from one aperture aligned with said one slot to another aperture aligned with said another slot, said one aperture being separated from said another aperture by at least one intervening aperture aligned with said intervening slot, whereby said end windings by being axially distributed beyond said cylindrical core by said winding guide discs are accommodated within the circular dimension of said core.
