ABSTRACT:
An armature for a DC motor includes a plurality of circumferentially spaced armature segments having salient poles with arcuate surfaces and air pockets formed within the poles adjacent to but not intersecting the surfaces, sized and located to reduce cogging due to variations in reluctance. The armature segments are preferably bridged by flux links carrying prewound electrical coils arranged in a circular path. Corresponding lamina in each armature segment are formed of a unitary stamping in which the segments are interconnected by removable flexible joints.
