V-Gate Drum Re-Imagined

thingiverse

Please don't chew my ear off about thermodynamics, this is just a demonstration in simple machines. One of the things that has always irritated me about the typical V-Gate design you see on the Internet is the cam design used to overcome the sticking point. Because the rotor magnets (effort) are closer to the axis of rotation (fulcrum) than the cam (resistance), it is a class 3 fulcrum. This is the worst possible design for something you're relying on to overcome any sort of force. Cam strikes, even against roller bearings, would abruptly diminish the main wheel's inertia. By placing the incline closer to the axis of rotation, it becomes a class 2 fulcrum where the effort and fulcrum are at opposing ends, exchanging distance for force instead of the other way around. And what happens when the cam puts the stator magnet out of commission? This means you're relying 100% on inertia as the overcoming force. In this model I have depicted 2 stator magnet assemblies with roller bearings which ride on a lobed cam that is fixed to the drum. As one stator magnet is interrupted, the other would- in a perfect world- continue to apply leverage to the cam and reset the opposing stator.
