ABSTRACT:
A method of manufacturing an armature for a DC motor comprising the steps of: (a) retaining a plurality of armature conductors pre-positioned in a pre-mold position; (b) placing the armature conductors in a mold; (c) adding to the mold a predetermined quantity of soft-magnetic particles, each soft-magnetic particle coated with a non-magnetic material, wherein said particles surround at least a portion of each of the conductors; (d) applying pressure to the mold to affect a compaction molding of the coated soft magnetic particles into a composite structure, wherein the particles and the non-magnetic material form a composite structure armature core substantially encapsulating the conductors within the armature core.
