And for your open source CAD needs I always recommend solvespace:<p><a href="http:&#x2F;&#x2F;solvespace.com&#x2F;index.pl" rel="nofollow">http:&#x2F;&#x2F;solvespace.com&#x2F;index.pl</a><p>If you want to try making motors, I&#x27;ve got a parametric 12-slot stator drawn up in solvespace - and a 10 pole rotor IIRC - ready to laser cut from steel. You should just need some magnets from say JKmagnetics, bearings and such, and you have a motor. Catch me a gmail if you like and I&#x27;ll send the files.
