Abstract
An electromagnetic machine stator has a common pole and a plurality of excitation poles. Each excitation pole has a coil wound around it for inducing a magnetic flux through the excitation pole. The common pole that does not have a coil wound around it for inducing a magnetic flux. A flux barrier, disposed within the common pole, inhibits the flow of flux from one part of the common pole across the flux barrier to another part of the common pole. The flux barrier is less conducive to the flow of flux than is the common pole.
