Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Have done some more testing with a 100s Star using capacitor doubler and got 470 W at 400 RPM into a battery 59 VDC 7.96 Apms. Capacitor values are 135 uf AC.

An 80s stator re wired as a 7x 2p Star using capacitor doubler and got 600 W at 500 RPM into a battery 59.2 VDC 10.13 Apms. Capacitor values are 560 uf AC.

So if both of these stators were put on the same shaft with the right blades >1 kW should be possible at a peak of 500 RPM.

Here's me thinking that was only possible with a Dual 36 pole cooper stators with black rotor caps.

Just goes to show the output potential can be improved, once load matching is better understood.

More test results to follow, as know there is still room for improvement..
There are realities if you do not accept, will lead to frustration because you will be spending time on wrong assumptions and the results cannot follow! The Dunning Kruger Effect :)
