    Hey Turion,

    Are you out there?

    Here's a ponder. You claim that your special generator works because it "out runs Lenz", right?

    If Lenz is out run at the speeds you attain, how can rail guns, using the principle, achieve velocities as high as mach10?

    I never could find a figure for the "speed of Lenz" in any literature nor did I have a means to verify (test) it. However you can see from this Wikipedia diagram that Lenz, or actually Lorentz, speed would have to be faster than projectile velocity.

    Thanks Guys, yes I follow Thane not Faraday, very good then, you guys are finally getting it. Machines with 50% waste heat are very low conversion efficiency. Old news. Faraday is a beginner. Axial flux generators are not all created equal. To understand, throw away that big ring first

    edit#3: I thought it was clear but seeing BM's reply, obviously not to him.

    The red line graph which I posted is a screenshot of an actual test of a magnet moving past a coil from a scope on the experiment. It is REAL.

    Thane's graph is from his imagination. It is garbage. Notice the difference. One is real. Thane's is a lie, falsehood, BS, garbage, etc. There is fact, science, truth and then there is BS. You choose.

    Bro, you say that axial flux has heat issues which is true. In some cases additional cooling is necessary but you have to realise a little motor giving 200 kw at 95% efficiency is going to be wasting 10kw as heat.

    What's Thane Heins stupid E bike? No less than axial flux.

    I realise that this is probably manufacturers blurb, but if it's true it's quite impressive.

    Interesting piece.
    I came across this too. Obviously a case of horses for courses.

    Some of this refers to dual rotor.

    30mhz and up is not a motor sorry. You are speaking off the cuff.

    Specify radial flux

    My intuition that GOES would be ideal for an axial flux generator is reinforced by this quote from Magnax.

    The Magnax Axial Flux machines use ThyssenKrupp’s high-performance grain-oriented electrical steel (GOES) for its cores. Grain-oriented steel can’t be used with RF machines because the flux paths in these machines follow a nonlinear 2D path. In the Magnax AF topology, the grains of the steel are oriented in the same direction as the flux paths. Low losses and excellent permeability of the grain-oriented material in the rolling (axial) direction results in a machine with 85% reduced stator core losses and a slight increase of the electromagnetic torque.

    Hi Quantum,
    Yes that is an awsome motor. And yes that was the funniest post ive seen here for quire a while. I was trying to be funny too, so i guess i wont be quitting my day job. In my defence i was trying pretty hard to cover it up, so as to avoid any blow back.
