I spent several months trying to replicate this. Best performance I could get was 300RPM on 30v for 20ma. I was waiting for Brad as he said he had a new improved design but that was 6 months ago. Certainly the 1+1=3 effect was present in a static test but I could not get the same performance when running. I have since removed the TPs and replaced with PMs. The rotor & TPs need to be precision cut to size. I was going to get something fabricated but was waiting to see the new specs which never came. Here is where I got to. https://youtu.be/_kmveZUMHF8 This is what I'm working on now https://youtu.be/DN3sllYB6VI same coils, flywheel, switching etc just PMs instead of TPs. Happy New Year!

First measurments (linear action) to remove the steel plate.

Check my math ?

second set / no calcs. yet.

The magnet configuration I have on my test bench is too
radically different from the Tinman configuration. These peak
force ratios are very different.

        Its not applicable here.   

I will have to wait for my neo magnets to show up.

Lets make this one go ------------------->
