ABSTRACT:
An armature for an electric motor has an improved integrated armature coil body. The integrated armature coil body includes an annular and substantially flat portion projecting a minimum distance beyond one end of an armature core, the annular portion being defined by curved connecting portions of separate winding wires arranged and disposed substantially in the Archimedes' spiral relationship about the center of the armature core. Each of the winding wires has first and second straight portions extending from the curved connecting portions through different slots in the armature core and connected to a commutator at the other end of the armature core. Each wire has two curved connecting portions, one overlying the other curved connecting portion of a plurality of other wires.
