You're right. I should have said no 12n10p instead of scorpion. But still none of them are 1. This is certain so we cant change that with several pages of spite. No one will consider "calculators" or math formulas not openly presented. I'm sorry there is no real contribution. Please don't confuse my post to mean I need or care about this calculator. I don't believe it exist and feel confident in the accepted confirmable calculation methods of SE Skaar, O. Krovel, R. Nilssen where

Kw = (sin (1 / 2nσ) ) / (zsin (nσ / 2z)) xcos (1 / 2nε).

This is has been reviewed and accepted by the IEEE so It works for most of the world maybe here is different. Part of the world must be Felix Niessenwho's winding scheme calculator concurs with the same result.

To find better efficiency between two motors the winding factor is not needed anyway. Its very simple. All you need is to calculate the THD %. And all you need to do this is a FFT scope shot of the generated emf wave measured in watts ,voltage, or dBm's

Thd(%)= the square root of (V3^2+V5^2+V7^2+V9^2+V11^2........+V(odd harmonic order)^2))/V1 where Vn is the rms voltage. n=harmonic order. In power systems a lower Thd translates to a higher power factor, lower peak currents and higher efficiency.
