While working on a couple other motor ideas I wanted to try this coil arrangement out as I have long suspected it would work pretty well in a low power/capacitor pulse motor without using a reed switch. I don't think this guy would have any issues running for long duration from a super cap, solar cell, whatever.
The key to mimicking the benefit of a reed switch at low power witn an SSG circuit is to simply be able to facilitate the self-generated trigger switching through as little rotor movement as possible. With these strong N52 magnets, and a very sensitive trigger coil we can achieve this pretty easily.
I have tried a lot of different combinations for these little motors and in the end the kind magnets were always instrumental to the operation. This motor just won't work the same without those double stacked neos. For me this is a perfect arrangement to try out some things because the rotor is fairly heavy for it's size, and at roughly 3v input @ under 3mA the wheel gets enough RPM's to generate 5v or so in a pickup coil pretty easily.
I was a little surprised how easy it was to get the wheel moving like it does without a whole array of coils like lasersaber's EZ Spin motors, though with just the one coil it's nowhere near contending.
