A windmill under construction. This is where the blades bolt on. Nothing to scale against here… suffice it to say it is HUGE.

Question by zeek Y: I want to build a windmill generator to recharge car batteries. Where can I find stator winding equations?
I wanted to learn how to wind the wires in a stator so that I can recharge a set of batteries in parallel. Where can I find the equations to do such a thing. For example, I would need to know the wire gauge, number of wire loops, and magnet strength. Thank you.
