At first blush, it appears to be a higher efficiency, greater torque motor than normal, but not an overunity COP system.  A starter motor is the extreme on the torque characteristic, because it will draw heavy current, overheat, and burn out if run very long at all. So higher torque versus shortened time of operation and motor overheating is a trade-off.  Looks like they increased the number of phases utilized and were thus able to sustain some higher torque longer, with less overheating etc. Increased efficiency helps, of course, so long as the motor has the necessary operational duration.  An average "good" electrical motor is around 50% efficient. One can get higher efficiency motors, however, e.g. from Hitachi and a couple of U.S. companies as well.  These perform at 0.7 and even 0.8. efficiency.  The Kawai process, e.g., is applied to such a motor to produce a COP which is about double the efficiency.  So the 0.7 and 0.8 high efficiency Hitachi motors modified by Kawai produced COP = 1.4 and 1.6, respectively.  The Kawai process is fully disclosed in his U.S. patent; all one has to do is be sure that the switching utilized is very efficient and adds very little load.

I only work on COP>1.0 systems, and then only with those inventors I personally know.  One never mixes inventors and inventions otherwise! It's a recipe for disaster.

Best wishes,

Can you improve on this idea, Tom? Can Bedini? Can Aspden?
I'm not an electrical engineer, but I watch the developments.
Seems interesting.
