ABSTRACT:
An armature disc for an axial air-gap, direct current electric motor in which the armature consists of two half turn metal discs laminated to the opposite surfaces of an expoxy resin impregnated laminate disc with the half turn of the one disc joined to the mating half turn of the other disc at the mating surface at the disc I.D. and O.D. The resin disc extends from the I.D. of the half turn discs across the commutator area of the armature at the armature disc I.D. and terminates at or adjacent to the O.D. of such commutator area. The half turns outward of said O.D. may be air spaced or laminated to the opposite surfaces of an epoxy resin impregnated spacer disc.
