SO, today I visited this junk yard called Pioneer Industrial Services.
Here's what I bought:
- 10 HP Century 230/460V 3 phase motor, clean looking:
A nice surprise about this motor is that it is not that heavy, perhaps
150-180 lbs. I can handle it alone.
- 7.5 HP U.S. Electrical Motors motor, dirty looking:
Both motors spin freely.
- Five 92 mF 500+ volt oil filled run capacitors, each the size of a vodka bottle, no PCB: 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 for them, maybe I will use them for something.
- A big Square D safety disconnect,
- A contactor, possibly wrong for the application,
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
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.
