  • Patent number: 4228378
    Abstract: This invention relates to an improved wire wound disc type armature for electric motors or generators. The armature has a disc shaped body mounted on a central shaft with a commutator formed of spaced insulated commutator elements located around it. The disc shaped body has opposing flat sides on which a predetermined number of wire windings are located. The insulated wire forming each winding extends outward from the commutator through a U-shaped wire channel on one side of the disc shaped armature and back through a corresponding wire channel on the other side. The disc shaped body of the armature is formed of high strength plastic and the wire channels are formed of laminated steel. In one embodiment, the wire then passes through an aperture in the disc shaped body associated with each winding and back out through the first wire channel and this is repeated until a winding of a desired number of turns is formed in the two channels.
