Abstract
Stator structures are provided. A stator structure includes at least a magnetic conductive layer and at least a first auxiliary magnetic polar layer. The magnetic conductive layer comprises a plurality of first salient poles. The first auxiliary magnetic polar layer is disposed above the magnetic conductive layer, below the magnetic conductive layer, or between two magnetic conductive layers. The first auxiliary magnetic polar layer comprises at least a second salient pole and a third salient pole. The total number of the second and the third salient poles is equal to that of the first salient poles. The second salient pole comprises permanent magnetic material.
