I'm working on my next windmill and have a question on the effect of a steel or aluminum stator support. I hope a picture shows below...
This is the base of my old assembly. I want to make a new one with dual rotors as well as replacing the wood stator mount with a metal disc that will hold the bolts that hold the new stator between the new rotors. I was about to make the mount out of aluminum until I read all the posts about eddy currents and decided not to. However on rethinking it, would a 1 inch gap between the alum plate and the back of the first steel rotor be enough to offset any ill effects? Or perhaps it would be best to use steel which would correspond somewhat like the steel hub on a trailer hub assembly. I'd better draw a picture...
The posts I read were about using aluminum backing for the stator itself where the aluminum would be between rotors and directly in the area of strong magnetic flux. I want to use the aluminum or steel plate outside this area.
So again, my question, can I use steel or aluminum for my stator mount (as pictured) without significant adverse effects? |
