Flux control and one-hundred and eighty degree core systems
Abstract
A two-phase or four-phase electric machine includes a first stator part and a second stator part disposed about ninety electrical degrees apart. Stator pole parts are positioned near the first stator part and the second stator part. An injector injects a third-harmonic frequency current that is separate from and not produced by the fundamental current driving the first stator part and the second stator part. The electric angular speed of the third-harmonic rotating field comprises .theta. ##EQU00001## where p comprises the number of pole pairs, .theta. comprises a mechanical angle and t comprise time in seconds.
