I want to build my own srm for a project.
>>180degree in max 100ms
>>Direction has to switch every 10-20 half rotations
>> position does not need to be perfect (maybe 10 degree off)
>>Inner Diameter 40mm outer max 100mm thickness max 10mm. Pancake build.

Is 6/4 or 8/6 better suited?
Will it work with this big inner Diameter?
I want to build Rotor and stator from 0,3mm special electosteel. Was thinking of max 10 pieces or 3mm.
Which current and windings are best for the coils?
