Rotating Magnetic Field's and Inductors.

[MileHigh]

Great observations PW.  I was expecting to see better efficiency also, perhaps 60% or greater.  I am not an expert in layout and other considerations like you expressed.  I like your thoughts about the rotor acting like a kind of "energy football" and creating a means for reducing the inefficiency.  In a way it's the classic apparent conundrum, "I add a load and my power consumption goes down."  Part and parcel of not accounting for all of your waste heat power and where it goes.

We can't forget that the basis for this investigation is "Proof that Magnetic Fields Increase Efficiency in Pulse Motors" as in when you add a spinning rotor in front of a pulsing coil to make a pulse motor.  The argument is that somehow the magnets themselves are acting like a source of power that is boosting the efficiency.  Or should that be lowering the inefficiency?

This thread reminds me of a project that I did years ago called the "Light Multiplier".  A number of people on this forum looked at it.  Here is the video where I did simple amp draw measurements:

  Nothing really special is going on here ---I think.  A Phd friend of mine did math calculations on it and found something interesting. He was going to build one for further study but I don't think that he ever did.

  Here is the build video if anyone wants to try it:

I think the real problem here is what people are defining as "work".  A turbo does not do any "work".  But when you add one to a gasoline or diesel engine it most certainly improves the efficiency.   Maybe that is not "work" but is is most definitely beneficial.   I see the rotor the same way.  Maybe the magnets don't do "work" but they sure seem to be beneficial in almost all the tests that have been done on this forum.  If you don't want to call that work that is fine with me.  But until I see otherwise I have to believe the rotor with magnets is causing a beneficial effect.

Lidmotor:

Great pair of clips and yes indeed the effect is there also.   Six years later and you are still making clips!

Carroll:

The rotor may improve the efficiency by reducing the inefficiency, if you get what I mean.  Nonetheless, you are still expending electrical power to make the rotor turn.  Brad is not stating that, and that's the sticking point.

It's not easy to do a full energy audit for a device.  In this case we are talking about a full energy audit without the rotor, and one with the rotor.  In the pie chart for the setup with the rotor, there is a slice, no matter now small it may be, that is the slice that goes into powering the rotor and making it spin.  There is no "magnet energy" slice in the pie chart.

    The energy pie gets eaten that is for sure. Everything grabs a piece of it.  Old Mr. Heat takes a big slice and never even says thank you.
  You raise a very good point.  Is there such a thing as "magnet energy" that can be added to the pie.  So far (going back hundreds of years) the answer has come up --no.
