This is dedicated to zubbly, This was one of the last things we talked about before he passed away
He passed away before I finished it, so he never got to see this machine actually make power in the short time I had it on a tower
Pardon the really sloppy post and maybe lack of detailed images I only took any of these to keep zubbly
up to date with what progress I made, and if I needed input. Its been years so details are also getting hazy.
(I'll update this with more detail as I find the pictures)
One day at a local scrap yard I dug up a 5 hp 3 phase electric motor, and remembering zubbly's success with these made a deal on it and brought it home.
After a few hours of chat with zubs, we came up with a plan to do this conversion in stages, to se if I would be happy with it at one stage or another, each of course costing more.

Torn down with some size comparison
On the lathe
I intentionally cut this thing so the surface was very rough, to the point of sharp to get epoxy to bond well
So far its held up well having done it this way, though it has been out of commission a couple years.
I have to find time to build or locate a new tower that can handle this thing.
Deciding on how to fit magnets here
Cheap easy way to hold the epoxy while pouring, after it was done I put it back on the lathe rounded, and smoothed everything
Skipping a bit while locating more pics,
This was the resulting waveform on an oscilloscope with the (16 round mags 4 sets of 4)
( Yes this scope was the one I got from Ratometer )
I really don't remember the output of this thing, and I only had it up a short time before the tower started showing signs it would not handle the torque. If I remember right I saw over 3KW a couple times in high winds, but it wasn't matched right to the load or the prop, so I don't really know its true capability yet
