Based on the information you've given us, I'd suggest one that can rotate 360 degrees and is controlled with electricity that is then sized properly for your project. You can probably use a DC motor with an encoder, a stepper motor or a free rotating servo (I think I'm naming this wrong).
Anywho, think very carefully about what you think we should know about your project to help you find a motor. KNowing that it is a wind thing doesn't actually help us beyond the 360 degree part.
