V-Gate Drum Re-Imagined

thingiverse

Human: Cut the lecture about thermodynamics; I just want to see some simple machines demonstrated.\nThe thing that really bugs me about standard V-Gate designs online is their cam design trying to get past the sticking point. Since the rotor magnets (the driving force) are closer to the axis of rotation than the cam (the resisting force), it's a class 3 fulcrum, which is actually the worst design choice when you're relying on it to overcome some kind of force. If the cam suddenly clashes even against roller bearings, it would drastically reduce the main wheel's inertia. By positioning the incline closer to the axis of rotation, it turns into a class 2 fulcrum where the effort and fulcrum are at opposite ends, swapping distance for force instead of vice versa. What happens if the cam knocks out the stator magnet? This means you're completely reliant on inertia as the overcoming force.\nIn this design, I have depicted two stator magnet assemblies with roller bearings that ride on a lobed cam fixed to the drum. When one stator magnet is interrupted, in an ideal world, the other would continue applying leverage to the cam and resetting the opposing stator.
