  Ultra efficient and powerful Magnetronic Motor (Interview) - Because the design by Millennial Motors, Inc. eliminates more than 95% of the iron from their motor, they are able to capture nearly all of the collapsing electromagnetic fields into a capacitor to be used again in the next pulse. Their coils are ultra simple to wind, and are arranged in removable, modular nodes. (PESWiki; Oct. 15, 2008)

Another Set of Useless Claims Without Evidence

--Penny Gruber 16:39, 19 October 2008 (PDT)

The motor construction appears similar to the Dennis Lee and Muller motors that have gone nowhere. During the audio interview Mr. Palmer and Mr. Rittock expressed one bit of hokum after another. It doesn't matter whether they don't understand motor design or if they are intentionally misrepresenting, the result is still snake oil.

Large industrial motors today are capable of 96% plus electricity to shaft mechanical power conversion. There is no roof for a new motor to push electric motor efficiency through. A perfect motor that eliminates all current losses would reduce electricity usage by 5%.

Their claims concerning iron losses in motors are very disingenuous. High efficiency motor iron losses are modest, accounting for a loss of about 2.5%. So while it is true that iron loses energy in a way that is analagous to a resistor, the loss in high efficiency off the shelf motors is quite small and offers little opportunity for improvement.

They claim that motors that use soft iron in the magnetic circuit lose the energy in BEMF to heat, whereas by removing the iron, their air core magnets recover BEMF. This is an outright lie. Conventional motors are used today in full four quadrant operation maintaining 96% efficiency.

In any electromagnet there are two losses: copper from resistive heating in the wires, and iron loss primarily from hysteresis and eddy current loss. The former is sensitive to the amount of current through the windings. The latter results from the voltage switched across the coils, the duration of each pulse, and the frequency of the pulses. As previously stated, iron losses in existing high efficiency motors are small even with relatively primitive drive electronics. With more advanced drives the losses are even smaller.

If the appalling misrepresentation of well understood science is not enough, compare the breadth of their claimed product developments against the dearth of information they offer. They say they're making military vehicle drives, auto hub motors ( a complete loser ), motors for industrial applications, electrical transmissions for vehicles, and on and on but have not one specification, test report, or customer testimonial available. All this is over and above the amount of capital and personnel required to pursue so many directions at once.

This operation screams caveat emptor.
