Thanks for the clarification, I now understand, it's a very efficient design.

It is but drops a little at lower loads,

Well done for pushing on with this project, I'm learning alot. 

With the rust concern of yours, maybe look at few layers of Q30 spray. It creates a protective skin against moisture, salt and corrosion. Just a thought. 

In the armature winding business they "satmos" treat motors to protect them against moisture may be worth a look into.

I have only started to look a using wind to generate power as i would like to move to the KZN coast and not sure how well the solar works there with the clouds but the wind does seem to blow often. So I will follow this project to see how this can be added to my future system. Thank you for the great information so far.

Not really.  The inputs I got and the questions is truly worth it.

On the ROI topic even severe criticism leads to the good as you start investigating matters.  Simply put when doing something criticism is often the best input and most valuable.

All inputs saves time, costs and improves the product.
The inputs on this topic thus far made me change some stuff and looked out for others and truly appreciated.

Today we start the winding process. There are a few interested in installing this so it is important to make this easy to replicate very low in cost and low in maintenance and easy to replicate.  The so called excuse in SA is we did no maintenance... 😇  But not one person was laid off. I recon I will get away with 4 bearings as movable parts.

My main concern is the rust factor in the magnet area.  The steel mounting and "flow" plates should have regular heat on it but the magnets facing the North Wester directly from the sea.  That is the main issue.

The prototype will be from mild steel the next one from stainless.  Therefore the reason to use carbon fiber as a medium light strong cost effective (except in F1) and durable.

If one does not have to do maintenance then make it that it requires no humans and therefore low costs.  Trust a robot ..
 

What started as a two or three unit has created other interests and best to spend time on the long lasting of it which I recon should be 15 years plus.

Your response reminds me of Elon Musk's reply:
