Hello Oztules!
It's been a long time! Hows things down under? I understand a cyclone went through your area, weather it okay?
Yes! I understand that I'm now on a "time line" to finish my project! I think I may be doomed!
I wonder if I have until 2012 to finish it.... or I've got until 2012 to use it?
It's still a project on the "shelf".. just put back a ways. I'm sure you understand how that goes! a bathroom to finish and house to fix up.. A pair of Allen Organ tube amps to rebuild (pair of 6L6s) great looking output transformers.. note the "look" a ways to go before I can comment on their sound! Also a pair of Dynacos Mark 3's.
I have added to my parts pile for the waterwheel project, if you have the time take a peek at my pics and look at the Kollmorgan servo motor, I sure miss Zubbly! I have a bunch of questions for him. Take a look at the number of magnets and the way the rotor is made, for all intents.. it's almost hollow, very low in mass, but yet it's a beast to move around, as is the the stator. I forgot (it's been over a year since I've played around with it) how much the motor weighs I'm guessing 80LBS (sorry, no metric values here!). I sure has LOTS of magnets! check out the surface area and compare it to what most motor conversions have. If you check out the end view you can see how thin they are, but that doesn't seem to be an issue.
not Sure the best way to configure it's wiring (not that it matters yet) It has 3 leads for each phase (u,v,w)??
I've a Kuboto tractor with a pto, was planing on spinning the motor with it and see what happens. Tractor is 18hp should be able to put some sort of load on it (the servo motor).
Anyways.. I sure stuck my finger in the socket asking about Boone Pickets!
