No Crack, but I did need asperin when the magnets flew off!!!

I think your evaluation is right because I was below rated speed and I did see a slight increase in input current.

Vince,

So ... set the RPM higher--

And repeat!

Yours was/is a VERY revealing experiment ....

It appears that the Perepiteia Motor is nothing more than a hysteresis brake.  Placing the steel rods (wound by coils) near the spinning magnets induces alternating magnetic flux within the rods, the resulting magnetic hysteresis causes drag on the rotating disk, and heat losses within the steel rods.  Shorting out the coils effectively shields the steel rods from the disk's magnetic field, eliminating the hysteresis drag.  This causes the motor to speed up - but not as much as it would if the steel rods were removed completely.

This was posted nearly 3 months ago and seems to be a very plausible explanation. Have any of the experiments since then produced results inconsistent with that theory?

Shane's latest video demonstration does not fit this scenario at all. The input load to the motor actually decreases (by about 50watt) with increased output speed only when the high voltage coils as well as the high current coils are connected to a load. With the high voltage coils at open circuit and only the high current coils connected to the load,the generator behaves as expected from text book theory. Besides, why would shorting out the coils shield the steel rods from the magnetic field anyway? Every time I have tried this with a permanent magnet generator, it just locks up.

CF,

As you so rightly note, a major new clue is the "high voltage."

Thanks thinks that his results are now determined by "electrostatics."  Not quite .... 

In fact, the real focus should be on the voltage gradient within the coils ....   And, how that is interacting with the magnets of his "generator."

purely theoretical  :

• scenario1:

arrangement as build by Thane, consisting of a prime mover and Thane's generator.
One coil with little impedance is installed, in close-circuit with a load.
Thane calls such a coil a "high current coil".

System is at rest. With a scope probe at the load (vs. ground) a horizontal line will show up on a scope. I call this the absolute zero-level of voltage potential. It is the same level as earth ground.

Now the prime mover starts to rotate.
An alternating current is produced in the circuit (i.e. in coil&load).
The voltage which got induced in the coil (when a magnet appeared and disappeared) could completely dissipate through the load as current before the next magnet approaches the coil.

The alternating current can be seen on the scope, alternating around the absolute zero level.
When the next magnet approaches, it gets repelled according to Lenz's law.

• scenario2a:

arrangement as above, except
one high impedance coil is installed, in close-circuit with a load.
Thane calls such a coil a "high voltage coil".

System is at rest. With a scope probe at the load, the absolute zero-level can be detected. It is the same level as in scenario1.

Prime mover starts to rotate.
Rotation is slow (below 'impedance threshold').
Same things happen as in scenario 1.

• scenario2b:

same as 2a except
prime mover rotates faster (i.e. RPMs are higher than 'impedance threshold').
The voltage, which got induced in the coil (when a magnet appeared and disappeared), could not completely dissipate through the circuit, due to the high impedance of the coil and the impedance of the load while the next magnet is already approaching.
The part of the energy, which was not dissipated got stored in capacitive reactance.
The amount of stored and not dissipated energy gets bigger with increasing RPMs.

The above, so far, is factual, I guess.

Now I would like to know:
- Is there any interaction between this stored (i.e. not dissipated) amount of energy and the magnets?

- If the coil-load-circuit is not grounded, is the zero level of the voltage signal rising compared to the absolute zero level, while the system speeds up in scenario2b?
In other words:
is the theoretical horizontal center line on a scope, above and below which the voltage alternates, rising?
Again in other words:
Is the voltage wave, as observed on a scope, shifting upward while the system speeds up?
(By "shifting upward" I mean compared to the absolute zero level)?

If so, does this mean that an increasing DC voltage potential and thus DC current is developing in the coil-and-load-circuit with increasing RPMs (having implications on the forces of attraction and repulsion between new approaching magnets and coils)?

edit: I struck the part about 'DC current' as the circuits are not grounded.
edit2: tried to clarify the stuff about the 'zero level'
