Please Help!,How many turns for a 12 pole cd rom 25mm motor?
I'm building a 25mm 12 pole motor using 2.5 25mm 12 pole stators and stock cans with a flux ring extensioncoming from another donor can, and 14 mags of 5x5x1mm mags.This is a homemade attempt at a build of a 25mm 12 pole motor using stock parts,no machining necessary ,only tools needed are a drill press,dremel with cutoff wheel and a soldering iron.Could somebody tell me how many turns should i do for a 2 cel 3d motor using an 8x4 HDprop,I,m looking for maximum thrust at 7.5 to 8 amps.Also I would like to know how many turns for a 3 cel setup using the same prop and aiming for the same amp draw.Thanks sentella

I have made a 25mm 12 pole stator motor. Useing a gobrushless costom bell and single can 14 1x5x5mm magnets and 20 turns of 26g wire. I wound 6 of the poles Useing AbCaBc wye wind on 3 1.73mm stators stacked. I had to use a drill and sand paper to make the stator smaller, and it was not easy to wind and keep the coils from shorting. But it was worth the effort. The motor runs verry verry smooooth and puts out 13 oz of thrust with a 9x4.3 gws prop at 6 amps with a 3 cell bat. and puts out 8 to 9 oz thust with 2cell batt.
