Hi Harald,

Nice work, have you had time to run it yet?

This along with Glenn's staggered winding will be an interesting read .

I thought about the 48 "thing" ,but just let it go as I just know you are too smart to make a mistake.

Hi Bruce

just finished wiring the last rotor of the LG's last night.
wired each phase different, I will measure only a phase a time and will multipy the output by 3,so only for delta wiring, in star wiring the efficiency is much lower and should be avoided. ( I would have to rewire for each test, that's to much.)
Configuration: 12P - all in parallel
2S-6P - 2in series-6 in parallel
4S-3P - 4 in parallel-3 in series

I have as well a new F&P 36 rewired in the same way to test it and compare. Now I need somebody to give me a hind how to put the data into a graph (which exel template ?) I used a "Line chart" from MS Word last time. This didn't place the rpms proper. See old listing. Hope somebody can help, please.

cheers

Harald
