We knew from the beginning that when we added the approach spiral to the single magnet in the LPSR proof of unlock principle model, that there was a problem experienced when the leading edge of the rotor left the magnetic field of the spiral that the trailing edge would experience a backward pull from the last few magnets in the spiral. I saw it as a challenge, something simply to think through, to overcome, not something to stop the device from working. I though, it would be so nice if those few magnets that create the back pull could just disappear. Well moving permanent magnets takes work, so that was out of the question. But electro-magnets can be turned on and off. If the electro-magnets field did not interact with the permanent magnets field then it would be the same as having a permanent magnet overunity motor that put out 1000 horse power and was connected to a conventional electric motor that put out 200 horse power for a total of 1200 horse power output. Mark is building a four foot diameter LPSR that will have a stator with NIB magnets close to 14 feet in length! After tests without the electro-magnets, the electro-magnets could replace the few that cog just before the spiral exit area. Just a foot or less out of 14 feet. That should make an overunity power output at the shaft many times over.
Quinn will make field simulations also and we will post results.
The research and development on the non contact LPSR designs will continue also.
Thanks,
Butch and the LPSR team
