Very cheap tools to be had here.
All (3) the electronic brush-less motor driver testers I have used startup in the midband when first plugged in. I have never found a site or a way to control these things where you can have them start at zero volts and then get ramped up from there using a computer.
Mind you, it's been 4 years since I looked so there may be stuff out there that I don't know about. :-)
It would be good if someone had a way of doing this.
There are sites out there that show you how to make your own outrunner motor but the ones I have found are in German or Swedish and Google translator or babelfish don't do a very good job of converting technical lingo.
You could make your own for whatever revs you need for your power supply. That would be nice for a small machine.

If you do make your own spindles for your outrunner motors then you could use the round tool steel blanks from the same site here.

Lots of different sizes to choose from.
The hardness/brittleness shouldn't be a problem for the power of these small motors.
