Abstract
Abstract A method of making self-supporting wire wound disc armatures by laminating the radial conductor portion of the armature and by coupling the winding to the commutator and hub by means of a laminate layer. The sequence of operations is arranged so that commutator connections can conveniently be made by hot staking and the commutator can be formed from a thin sheet metal blank.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
A method of producing wire wound disc armatures including the steps of laying down a first flat annular ring of resin impregnated sheet material, depositing insulated wire upon said annular ring to form a closed armature winding having generally radial conductor segments lying on said first ring and inner and outer crossover connections extending beyond the inner and outer peripheries, respecively, of said first ring, laying down a second flat annular ring of resin impregnated sheet material over said insulated wire and said first ring, and applying heat and pressure to said first and second rings thereby causing said resin therein to flow to provide a substantially flat laminated armature.
Claim 2
Independent Claim
110 words
A method of producing wire wound disc armatures including the steps of laying down a first flat annular ring of resin impregnated sheet material, depositing insulated wire upon said annular ring to form a closed armature winding having generally radial conductor segments lying on said first ring and inner and outer crossover connections extending beyond the inner and outer peripheries, respecively, of said first ring, laying down a second flat annular ring of resin impregnated sheet material over said insulated wire and said first ring, and applying heat and pressure to said first and second rings thereby causing said resin therein to flow to provide a substantially flat laminated armature.
Claim 3
Dependent Claim
18 words
The method according to claim 1 wherein said resin impregnated sheet material is an epoxy impregnated glass cloth.
Claim 4
Dependent Claim
64 words
The method according to claim 1 wherein said insulated wire is deposited on to a winding form, sufficient heat and pressure is applied prior to removing said winding from said winding form to fix the winding configuration by hot tacking; and additional heat and pressure are applied after removal of said winding from said winding form to laminate said winding between said annular rings.
