Windmill Generator - why won't a small brush-less motor work as a windmill generator?
I bought a small brush-less motor that was designed as a motor for a small RC plane. I tested it by spinning it with a drill. I was surprised to find that the motor did not generate much in the way of voltage. Why not?
It's too bad - many small brush-less motors are so nice. No brushes, ball bearings, and low cost. I would have thought that forcing a brush-less motor to spin would have generated power.
