Here's an ultra-simple sanity check. It's so simple I can't understand why no one (to my knowledge) has suggested it.

Because the coils in his machine are either shorted or open, they produce no power. So if it provides any benefit at all, it would be by accelerating the motor past its normal no-load speed, i.e., without the apparatus in place.

So just remove the entire apparatus from the motor! Get rid of the electromagnets, the rotating disk with the magnets, everything. Leave just the motor, its drive circuit,  and the motor speed sensor. Apply power to the motor as usual. How fast does it run?

If the motor runs slower without the apparatus than with it, then it may be argued that the apparatus provides some sort of benefit to the motor, at least when the coil switches are closed. But if the motor runs faster *without* the apparatus, then it's obvious that the apparatus is a net power drain that only slows the motor down. It may slow it down a lot with the switches open and just a little with the switches closed, but in either case it's a net drain on the motor.

Your ultra simple check sounds reasonable, but it should be understood that power and efficiency are two different things. I can make an AC or DC motor run as fast as I want by increasing frequency or voltage but this does not imply that the efficiency nor the power required to operate the motor has changed. Thanes motor could easily lose speed but gain efficiency and power, that is why energy in Vs energy out must be calculated to show efficiency and the motor must be loaded to calculate power. At the end of the day, Peak efficiency at Peak power levels is what our goal should be. I have a few motors that are super efficient but produce very little power which makes them very expensive paperweights ---nothing more.

WHEN A COIL IS OPEN NO CURRENT FLOWS.
WHEN A COIL IS SHORTED - MAXIMUM CURRENT FLOWS AND ALL OF THE POWER IS DISSIPATED WITHIN THE COIL ITSELF AS JOULE HEATING (see Lenz's Law below) RATHER THAN BEING DISSIPATED IN MORE THAN ONE COMPONENT IN THE CIRCUIT.

Lenz's law
From Wikipedia, the free encyclopedia
Lenz's law gives the direction of the induced electromotive force (emf) and current resulting from electromagnetic induction. Heinrich Lenz formulated it in 1834.

Definition
Lenz's law states that any induced electromotive force will be in the direction such that the flux it creates will oppose the change in the flux that produced it.

Connection with law of conservation of energy
Lenz's Law is one consequence of the principle of conservation of energy. To see why, move a magnet towards the face of a closed loop of wire (eg. a coil or solenoid). An electric current is induced in the wire, because the electrons within it are subjected to an increasing magnetic field as the magnet approaches. This produces an emf that acts upon them. The direction of the induced current depends on whether the north or south pole of the magnet is approaching: an approaching north pole will produce an anti-clockwise current (from the perspective of the magnet), and south pole approaching the coil will produce a clockwise current.

To understand the implications for conservation of energy, suppose that the induced currents' directions were opposite to those just described. Then the north pole of an approaching magnet would induce a south pole in the near face of the loop. The attractive force between these poles would accelerate the magnet's approach. This would make the magnetic field increase more quickly, which in turn would increase the loop's current, strengthening the magnetic field, increasing the attraction and acceleration, and so on. Both the kinetic energy of the magnet and the rate of energy dissipation in the loop (due to Joule heating) would increase. A small energy input would produce a large energy output, violating the law of conservation of energy.[/color]

This scenario is only one example of electromagnetic induction. Lenz's Law states that the magnetic field of any induced current opposes the change that induces it.

For a rigorous mathematical treatment, see electromagnetic induction and Maxwell's equations.

Practical Demonstrations
A brief video demonstrating Lenz's Law is at EduMation.
A neat device made by William J. Beaty levitates a magnet above two spinning rollers.
A dramatic demonstration of the effect with an aluminum block in an MRI, falling very slowly.
A demonstration that even a small child can try:
- Find a small electric motor.
- Spin its shaft.
- Connect its wires together (with a paper clip or alligator clip), and spin the shaft again.
- This time, the motor resists turning, because current can flow through its wires.

So if it provides any benefit at all, it would be by accelerating the motor past its normal no-load speed,
ASSUMING YOU CAN RUN AN INDUCTION MOTOR PAST ITS NO-LOAD SPEED WHICH = MINIMUM OR NEAR ZERO SKIP ANGLE?

So just remove the entire apparatus from the motor! Get rid of the electromagnets, the rotating disk with the magnets, everything. Leave just the motor, its drive circuit,  and the motor speed sensor. Apply power to the motor as usual. How fast does it run?
APROXIMATELY 3500 RPM

If the motor runs slower without the apparatus than with it, then it may be argued that the apparatus provides some sort of benefit to the motor, at least when the coil switches are closed.
GOOD PLAN BUT WE HAVE NOT BEEN ABLE TO RUN THE SYSTEM "SAFELY" BEYOND 1500 RPM DUE TO THE FACT THAT WE ARE ALL SISSIES.

But if the motor runs faster *without* the apparatus, then it's obvious that the apparatus is a net power drain that only slows the motor down. It may slow it down a lot with the switches open and just a little with the switches closed, but in either case it's a net drain on the motor.
OUR PROTOTYPE IS MEANT TO PROVIDE PROOF OF CONCEPT FOR OUR ABILITY TO ACCELERATE (see red section in previous email) THE SYSTEM UNDER MAXIMUM LOAD (SHORT CIRCUIT) - WHEN THE LAW OF CONSERVATION OF ENERGY SAYS THAT THIS SCENARIO SHOULD RESULT IN DECELERATION.

Here's an ultra-simple sanity check. It's so simple I can't understand why no one (to my knowledge) has suggested it.

Because the coils in his machine are either shorted or open, they produce no power.

Not true, when shorted without the steel rod in place they slow it down more, there is power being produced, a short is not the most useful load but it is one hell of a load.
There is also voltage, although it is hard to measure in a perfect short, you must calculate it by knowing the resistance and current, and to some extent inductance

So if it provides any benefit at all, it would be by accelerating the motor past its normal no-load speed, i.e., without the apparatus in place.

So just remove the entire apparatus from the motor! Get rid of the electromagnets, the rotating disk with the magnets, everything. Leave just the motor, its drive circuit,  and the motor speed sensor. Apply power to the motor as usual. How fast does it run?

Ah, so you're crazy!
The motor is slowed down hugely by the core losses even when the coil is open circuit, there are eddy currents and hysteresis.
Without any load it will run very much faster indeed, somewhere near 3600rpm minus slip.

If the motor runs slower without the apparatus than with it, then it may be argued that the apparatus provides some sort of benefit to the motor, at least when the coil switches are closed. But if the motor runs faster *without* the apparatus, then it's obvious that the apparatus is a net power drain that only slows the motor down. It may slow it down a lot with the switches open and just a little with the switches closed, but in either case it's a net drain on the motor.

No, the crux of this device is that by shorting the coils it some to a relatively swift stop, UNLESS there is a fully magnetic path to the motor in which case it energetically accelerates.

What is super strange is that a powerful magnetic field improving the power of some types of electric motor a little does not seem all that far fetched, but the flux path and source of flux source are so poor compared to the magnitude of the effect (an effect that works with other types of motors also) that it seems something a little strange must be going on.
