Abstract
A motor assembly having improved flux properties comprises a rotor lamination rotatably disposed within a field lamination. The field lamination comprises a constant cross-sectional dimension, and is configured to provide a pair of opposed, tapered yokes that provide constant impedance to the rotor lamination. The rotor lamination includes a plurality of spaced teeth that are dimensioned so that taper of the yokes changes by a factor of the width of one of the teeth, thereby reducing the material needed to adequately carry the magnetic flux of the rotor lamination.
