Abstract
The armature has a circular cylindrical main body that is surrounded at one axial end by a circular flange. The flange can conduct what would otherwise be stray magnetic flux and because the flange is on a substantial radius, it can provide a significant area for the magnetic flux even though the flange's radial dimension is small. A number of channels are formed in the armature to provide for passage of fluid past the armature.
