is it possible to turn a three phase squirrel cage induction motor into a generator?

Or even a single phase one?

Working on any speed (1% ->50% the synchronous RPM) + Grid tie, single and 3 phase alike.

Actually, induction machines are commonly used in wind turbines, and they do not receive grid excitation. The trick is to connect the the stator to some capacitors - this will set up a resonance with the inductors and provide the magnetization necessary for generation.

The key-word is self-exciting, but I don't find a lot of information.

Thanks for the info, I found an other site that makes it sound easy.
Yes that is a better link - best wishes for yours - be sure to publish an Instructable eh? L

. As a rule-of-thumb, squirrel-cage motors won't work as generators. It can be done, but just not very practical.

Thanks, i know it's not the best idea but ive got a lot of them lying around.
