Ok,, I've done some testing on different stators and can see a plus and minus on some of them ... A couple of the members have told me I need more "refined" driving ,,I'll have to modify my drive -system for that. But ,just now this is nice and quite, steady, and seems to give an "overall" picture of whats best and whats real bad ..

Hope you like the set-up

I've tried 3 times to post the pic ,,the developers must be on a RDO.

Dunno,,must be having a bad day ..tried 5 times..

Tell me more Bruce, what was causing the problem? Weere you getting an error or something? It may be something I've done.

Hi Bruce,

you must have the fresh paint smell all of the time.

I have some preliminary data on my F&P 100S. 55VAC unloaded at 325RPM in delta. This should be right on the money for my boost buck system with 3m dia rotor. My mate Peter has done a great job with the mods.

Some test data in your own time. .. .. Gordon.Edited by GWatPE 2008-04-23

Hello Glenn,, I scrapped the original loaded pictures and re loaded them in my album .This must have fixed the problem..

Thank you for your concern,,,The testbed is working very nicely.. I'd like to lend it to anyone out there, but the thing weighs a ton,,but you's are allways welcome to come around ,,to the funny farm...lol

Hi Gordon,,
Can't really tell so far ,,,testing has been done with different "re-wires" ,but have to evaluate the rpm verses the different wire sizes ,configurations,neo/ceramic rotors ,Etc.

I'll get back to it when I return --One two sleeps to go and I go to "George-of-the-jungle" land--

Gordon and Glenn,,

I put those pic's in just to see if the "uploading " is working --perfect,,must be the knucklehead down this end ,,nevermind.
One is of the Diode rectifier bank ,Mosfet bank and blocking Diode heatsink for the dummy load. I've installed a small 12v pc fan under the blocking Diode to keep it cool ..Must do the same to my brain one day !!if there's one left!!

Have fun

Bruce, I can see stacks of F&P stators on your picture. Where did you get them all from? I got just one, donated from a friends broken washing machine.

You would not happen to be in Perth, WA by any chance?
perhaps we should hold a little competition who has the most complete F&P stator/rotor assemblies

hi tinker, im in perth, clarkson to be exact. i have quite a few assemblies here, a lot of 60 series and some 80 series.
if you want a couple i can let you have them. i use to sell them on ebay but its too much hassle so i have a few left over, let me know if you want some, theres no charge to forum members.

Hi Bruce,
Nice work. Any chance you could post some close up pictures of how the mounting assemble. Specifically how the shaft and bearings fit into the base plate.

I'll need to setup something like this for some tests I plan to run in the near future.

Thanks in advance,

Nathan
