Internal/External Split Field Generator ORNL researchers developed inventions to improve the efficiency of electric generators. This is achieved by decoupling the magnetic polarity of the driving mechanism while increasing the operational frequency of the machine. These technologies offer unique, low cost methods to produce a generator with a higher power density. In both inventions, generators …

External Split Field Generator Disclosure Number 200802199 Technology Summary This invention is a novel form of electric generator that uses the flux interactions between moving and stationary magnetic fields to produce twice the flux change per rotation of the prime mover. In conventional electric generators, the rotation of the prime mover produces one …
