I'm working a project that will use a hard drive spindle to hold a high speed rotor to drive a small generator. If I could just use the spindle motor as a generator, it would greatly simplify the project.
I've looked this up online, and the main consensus is that unless you spin it at operating speed, you won't get enough power to do anything, but no mention of how much power that is. I should have no problems hitting 10 to 20k RPM with this, so spindle speed is not an issue. I just need to know if I can squeeze enough power out of this to run a micro, some stepper motors and some solenoids.
Oh course I plan on building a prototype and testing it, but I would like to have some idea of what to expect before I get that far in.
