On you extra heat thing, I am expecting to be a direct relation to the
velocitythat rotor goes. It should increase with RPM..
Is this correct for what ever reason it does it??
Steorn:
Noheat is produced by Joule Heating (google Joules 1st Law).

Yet if an energy "gain" is done with the coil via "inductance
change", and the faster it goes, does this energy gain increase??
If so the loss in the fly back will produce more heat to loss, as the rotor
velocity speeds up.. Then the extra heat signature should increase the fasterit
goes.
Correct?? Or am I lost as usual here???
Steorn:
Ok there is a whole load of things mixed up here. If we take a classical view
of any system, there are no losses or gains, just changes in forms of energy.
So your comment that the diode increases losses is just not true - it changes
theform of some of the energy conversion.
As for the change in inductance - its independent of rotational speed.
The amount of energy converted to heat thru Joule heating reduces per
revolution, but the amount of heat power produced is always the same (same
dutycycle, no BEMF).

Thanks. I got some some clarification from that. Adapting to your terms I
think. No increase in "gained" energy per velocity. And that is what I was
asking. The variation (faster or slower) in induction change does not cause an
increase in "gain".
Diode is not a problem a voltage drop that would be expected. And a capacitance
to the coil when travel is in the other direction. All the traces show normal
with this.
Yet I have learned to ask.
Steorn:
Ok- to be clear as the rotor speeds up the mechanical power increases, the
electrical power remains the same and the power to heat remains the same.
