Here's what I bought:
1. 10 HP Century 230/460V 3 phase motor, clean looking: $40
A nice surprise about this motor is that it is not that heavy, perhaps
150-180 lbs. I can handle it alone.
2. 7.5 HP U.S. Electrical Motors motor, dirty looking: $20
Both motors spin freely.
3. Five 92 mF 500+ volt oil filled run capacitors, each the size of a
vodka bottle, no PCB: $5 for all five. The owner did not know what
they were, I pretended that I did not know either. I said, these
pieces look interesting, I will give you $5 for them, maybe I will use
them for something.
4. A big Square D safety disconnect, $8
5. A contactor, possibly wrong for the application, $3
The guy is actually nice and pleasant and sensible. I also dropped off
a huge transformer that I could not get rid of otherwise.
My plans are as follows: I will make a self starting rotary phase
converter, as outlined in
(see "Self Starting Phase Converter")
I will use 3 of my 92 mF capacitors, connected in parallel, between
leg 1 and leg 3 of the 10 hp idler, if I use a 10 HP idler.
I will create a web page about this project.
I have a question, is there some convention about leg numbering and
direction of the rotation of motor shafts? I do not want things to
rotate backwards and I want to do that in some conventional manner.
I really liked that junk yard, I will definitely go there again.
