Anyone know where I could find very small low RPM motors or very small stepper motors?
The only perfect ones I found were from companies that do distribution only.
Thanks!

Are these small enough? Bipolar stepper, pretty good torque for it's size. I didn't use their circuit, just something quick and dirty, wasn't real smooth, but probably my fault... Worth a buck a piece to try. Was going to use them on a tiny robot, never got around to it.

It is a motor and does not include a turbine.Can be used as a turbine/generator?
Also it is a permanant magnet motor?
Altanore, a good place for small steppers is DVD/CD and old floppy drives. The motor that drives the pickup assembly back and forth is a stepper, very small.
HDD's probably not, but the motors that drive the average CD/DVD optical head are small steppers, I've taken several dozen apart.
I Google CD/DVD drives and find many references to steppers in them. Why aren't they accurate enough? Feeding a stepper from a decent sine wave source and they're smooth as glass.
I'm really pretty sure they're steppers. I don't think I have any floating around right now but I might have a junk CD floating around I can scrap to find out. Should only take a few seconds with a multimeter to figure out if it's DC brushless or a stepper.
I could be mistaken though, I never noticed any feedback from the brushless motors though how would you accuratly control their position, I don't recall seeing encoders anywhere, but I usually just gut them for the spindle motors.
