Abstract
Abstract A spool for carrying a field winding and an insulator for carrying leads connected to the ends of the winding are located on opposite sides of an intervening rotor segment. Barrellike projections on the insulator extend through openings defined by the spaces between the pole tips of the rotor segment and engage apertures in ears extending radially from a circular flange on the spool. The leading end of the field winding is guided out to a terminal on the insulator from a central region on the spool through an undercut protective groove on the inside of the flange and then through the aperture and bore in a mating set of ears and projections. The terminating end of the field winding is guided out to another terminal on the insulator through apertures in another mating set of ears and projections. The ends of the field windings are terminated with leads held by the insulator and connected with slip rings.

Claim 1
Independent Claim
243 words
In a rotor for dynamoelectrical apparatus a. a shaft b. a rotor segment mounted on said shaft and having a wall defining first and second surfaces Extending radially and terminated by a plurality of pole tips, said pole tips have radially extending portions defining openings therebetween; c. a spool member mounted concentrically with said rotor element and having a center region bounded at one end by a disk-shaped flange located adjacent said first surface of said rotor wall and having a periphery and an ear with an aperture therethrough, said ear extending radially from the periphery of said flange to one of said openings between said pole tips; d. an insulator member having a hub region mounted concentrically with said rotor segment and having a tongue located adjacent said second surface of said rotor wall and extending radially from said hub region to said one of said openings between said pole tips, said insulator having a projection with an aperture therethrough and extending through said opening and into said aperture of said spool ear, whereby said projection restrains said ear radially and axially and whereby said spool and said insulator mutually position each other adjacent said first and second rotor wall surfaces; e. a slip ring mounted concentrically with said insulator and a coil wound on said spool; and f. a conductor connecting said slip ring and with said coil through said opening and through said apertures in said projection and said ear.
Claim 2
