Hey all. Mate of mine is designing a mechanical motar and pestal for his final year project at uni. Both he and I suppose, are after some pointers/advice on what motor to use. Initially I though he could flog a motor out of a food prossessor but he'll need all sorts of gearing to reduce the speed and this adds complexity and more chances for parts to fail. I guess were after a bit of a heads up as to whats out there in terms of low speed high torque electric motors. I'm guessing this will restrict us to purely DC?? Thanks.
