DYNAMO-ELECTRIC MACHINE LAMINATION CONSTRUCTION A lamination for use in a dynamo electric machine of the kind employing a stacked laminated stator and/or rotor, is formed of a flat annular plate of ferromagnetic material having a given outer diameter and a bore opening of a certain inner diameter. The plate has a number of equally circumferentially spaced lot opening extending from an intermediate circumference to form a number of teeth which extend radially to an air gap periphery of the plate. The slot openings are formed to contain electrical conducting elements which extend axially of the lamination stack to correspond to an n pole operating configuration. The annular plate includes a tooth portion defined by the teeth between the intermediate circumference and the air gap periphery, and a yoke portion defined by a continuous surface of the plate between the intermediate circumference and the periphery of the plate radially opposite the air gap periphery. For a given ratio of inner diameter to outer diameter for the plate, the teeth are sufficiently wide relative to the area of the slot openings to that the ratio of flux density in the tooth portion to flux density in the yoke portion in response to current passed through the conducting elements, is optimized for a given n pole operating configuration of the conducting elements. |
