     ""Sorry I don't understand your point, or are you also the poster in the closed post? I fail comprehend how that post refered to air core alternator's in particular, not cogging.""

Oh no, I'm not the poster from the closed post. I just didn't understand the problem with that post and suspected it was that I might not understand the terms. I thought it was a clear question when he wrote,

 "if anyone has experimented with a variable airgap of some kind to control cogging"

And then I was confused when I saw the reply,

"Airgap alternators DO NOT cog. period.[CLOSED]"

So the point of my post was to ask shouldn't the above statement be,

"Air CORE alternators do not cog." (core, not gap)

     I'm not very good with getting my point across, sorry if I only muddied the waters. I thought that since the post referenced overcoming cogging that it was clear it was not an air core alternator and also that it was most likely an axial as opposed to radial design. I assumed he was looking for some sort of mechanical way of closing the air gap with centrifugal force. Oh well, I think I am ok as far as understanding air core / air gap.

Thanks,

Andy I believe the point is the poster had enough knowledge to realise that moving the magnets away from iron cored stators will reduce cogging. Some experimenting has been done with Fisher and Paykil units on that point.

So it is not unreasonable for the poster to be more informative in the question. I know when people are new to a field (in this case electricity) knowing how to ask a question is a little confusing, the poster may fall into this area.

Assuming it was a genuine question badly worded then it's to be hoped he/she will re-post a clearer question, hint, post it in the middle of the night US time, the moderators are usually making zzzz.
