1. If an electric motor is spinning freely at its max RPM with no load on it, there is _no_ extra torque available from the motor! All the mechanical power produced goes into overcoming bearing friction, brush friction, windage, electromagnetic effects, etc. If you put a load on it, the speed will change, and the power consumption will change, until a new equilibrium is reached.

At least the motor in my demonstration is actually driving a mechanical load; the tape flag is moving quite a bit of air.

2. Is electricity being "produced"? That all depends on what you mean by "produced". It's not coming out of thin air! Nor is it coming from "magnetic plasma" or other fictitious sources in these experiments. The changing magnetic fields of the armature, produced by the brushes energizing segments in combination with the motion of the armature itself, "produce" or rather INDUCE currents in the stator coils, in perfect accordance with Faraday's Law of Induction. The faster the magnetic fields _change_ through the stator coils, the greater the induction effect.

That is correct.
And if the motor is configured correctly,then we can increase the speed,increase the load,and decrease power consumption.
Open case demo modle will be done by weekend,and posted here.

If you want to be rigorous then measure the input power this way.
Output power can be filtered out with that circuit, too.

There goes the weekend... and the footy

I hate to bring up PL book but he does talk about BEMF as Pin. Isn't that what this is. You've found a way to use this extra Pin rather than work against it? You draw current which causes more Pin in the form of BEMF. Just my simple logic.
