ABSTRACT:
A DC motor magnetic circuit configuration having reduced flux leakage and improved flux density that leads to greater motor efficiency and a higher motor constant. In one embodiment of the invention, and improved permanent magnet DC motor is provided that has a stator frame supporting a plurality of pole pieces in proximity to a rotor rotatably accommodated therein. The improvement comprises at least one of the pole pieces having a pole face lying in a plane that intersects both isotropic and anisotropic planes of the pole piece.
