ABSTRACT:
A shaded pole lamination is disclosed which includes a rotor opening positioned asymmetrically with respect to the sides of the lamination so as to increase the metal available to carry the magnetic flux on the side of the main pole which is farther from the main coil. In addition, shading coil recesses are provided which are grouped with respective reluctance gaps and crowded into the region near the reluctance gaps in order to maximize the area of the main poles. The shape of the lamination adjacent the reluctance gap has been modified to further increase operating efficiency.
