Need HELP with odd 2 speed PSC motor
Need HELP with odd 2 speed PSC motor
(OP)
First post, if not in the right place, please don't beat me up. I'm a poor aerospace undergrad, mechanical masters who has been doing something else for a decade. Dad was a EE but is no longer with me, so I need help.
I have an odd motor for a vintage lathe I bought. It is a German or Austrian ELIN motor of 1970 vintage. This was from the factory a 2 speed PSC (I presume) motor. However unlike your average air handler multispeed unit, this thing had 2 individually wound start/run and 2 individually wound run coils. A picture worth a thousand words and all shows how it was wired from the factory.

So unfortunately I bought it as a rewound motor without any data, and it has 8 black wires hanging out, not the 6 color coded it came from the factory with. The previous owner never had it working and hooked up a couple capacitors fairly randomly I feel.
Lead numbers are my fiction, what I wrote on my tags.
In short I have 2.6 ohms between two sets of pairs (my numbering 2 & 6 and 3 & 7
respectively.)
I have 4.2 ohms between 1 & 5
I have 2.1 ohms between 4 & 8
as shown in my picture of how it was when I got it:

leads 1 & 2 and leads 3 & 4 were tied together possibly by the winder when I got it and leads 7 & 8 were attached to either side of 60 uF run grade cap but I figure that to likely be nonsense. One of these caps would have actually been for another motor on the same machine. If one of you smart EE types could edjumacate me about how to hook this up, much appreciated.
TIA

Try posting your images to the engineering.com website - step 3 when posting a reply. Most of us don't have access to that Yahoo group, and the first link just seems dead.

If we learn from our mistakes I'm getting a great education!

Hope that works, will attach the last in the attach section as well. Again much thanks to anyone brave enough to help.
