Abstract:
1. A rotational coupling device, comprising: a rotor coupled to an input shaft for rotation therewith, said input shaft disposed about a rotational axis; a field shell disposed about said input shaft and fixed against rotation, said field shell defining axially extending, radially spaced inner and outer poles and an end wall extending radially between said inner and outer poles, an electrical conduction assembly disposed within said field shell between said inner and outer poles and on a first side of said rotor, said assembly including a conductor disposed within a shell, said shell including a radially outwardly extending flange disposed proximate said outer pole of said field shell and said end wall; and an armature disposed axially between said rotor and a brake plate on a second side of said rotor opposite said conductor, said armature coupled to an output member wherein said flange is affixed to at least one of said outer pole and said end wall of said field shell at a plurality of points located further outward radially than an outer diameter of said conductor by a plurality of fasteners, each of said plurality of fasteners extending through said flange and into said field shell at one of said plurality of points and each of said fasteners having a head abutting a first side of said flange opposite a second side of said flange facing said field shell.
