I crunched the numbers in Jim Murray's first Dynaflux presentation. Keeping in mind that he uses a solid metal rotor moving across a magnetic field creating extreme eddy currents, added with the inducted current creating even more eddy currents. Not to mention using input power to create the EMF, all the bearings and resistance, plus flux losses in the system. So lets put all that aside and just concentrate on if the input increase from unloaded to loaded broke the homeostasis of normal generators or transformers.

Unloaded, he was using 435 watts just to get the system going with no load.. When loaded, it jumped about 35 watts to about 470 watts. So we have a 35 watt increase of input. But His output was 40 watts. Which calculates to about a 12.5% reduction of back torque.

Normal generators have 100% back torque. His has 87.5%. It is my guess that the back torque was almost all from the eddy currents in the system. Even so- he still managed to decrease back torque contrary to known machines.

With the spiral magnet rotor, we can avoid most these eddy currents altogether.. The only eddys we face are from the output coil cores. And we can cut this further by using laminations. Or we could even avoid all eddy currents by using air core coils.

So all systems are a go.. My rotor is finally on the last leg of printing.. Hope it comes out nice!
