Because the interacting fields are essentially perpendicular and the toroid is saturating, looking at this from the perspective of linear superposition is not productive. The motor needs to be considered from the point of view of a parametric interaction. There will be essentially no CEMF because of the perpendicular fields. A higher current will be required to saturate the core when the magnet is present, which suggests that more energy may be required. The interaction and energy input is quite difficult to calculate due to the inductance variation and the combined fields. There is no new physics in this motor. This does not prove that the design cannot be overunity. I have tested many magnetic parametric transformers including soft materials and magnets in many geometries. I started out with efficiencies around 30% but with carefully selected geometries, materials, frequencies and path reluctances obtained efficiencies of over 95 % energy transfer but so far no overunity. Motors with moving magnets in a parametric mode is something that I have considered but not built. George Holz Varitronics Systems
