<p>A new class of doubly-salient machines which incorporates a specific stator/rotor pole arrangement to provide a linearly increasing flux linkage over the entire area of pole overlap, and either stationary permanent magnets (22, 24) mounted in the stator (10), or one or more auxiliary field windings coiled about the stator, or a combination of stationary permanent magnets and auxiliary field windings. In each of the three cases, the permanent magnets or auxiliary winding(s) generate the primary flux and block and thereby limit flux in the ordinary path of the secondary flux (due to the stator windings) through the stator. The altered magnetic structure utilizing four stator (12) and six rotor poles (18) increases efficiency when operated as a generator, and provides greater output torque when operated as a motor.</p> |
