Empirical equations predicting Newman Motor performance

[guruji]

Hi Kmarina today I tried to put five magnets together to make them all five N facing upwards. I could not do it cause they're repeling each other??.
I only have to put them one on each other to have a bigger magnet?
I was going to use a soft alloy rotor to attach the magnets to instead of the wood is it ok this?
Thanks

Yes and yes.

I use a steel shaft and square bolts and attach my magnets to that. So it is possible to use the soft alloy rotor to hold it. It might actually help with the concentration of the field lines. Wood is not a good choice in my opinion.

I had developed the empirical equations above from a limited data set.

Now I have compiled much more data into excel format. As you can see, this is far beyond what I was doing just two and a half weeks ago. See attachment below (uploaded as .pdf to save space).
