Whenever an electric motor or generator passes a circumferentially varying magnetic field through its ferromagnetic stator, it creates magnetically induced losses. These losses limit the efficiency and performance. Revolution’s technology operates without a ferromagnetic stator, allowing electric machines to reach their fullest potential. Our motor and generator products are able to operate with independently-tested efficiencies as high as 99.3%. Revolution has developed several air core armature technologies for maximizing efficiency, proven in volume production.
