2 speed 3 ph motor circuit diagram needed
(OP)
Hello,
I colleague of mine has a boring machine that is 3 phase 2 speed. The machine is changed to 1 phase, and also only 1 speed. He wants now to reverse this, and make it 3 phase and 2 speed again, so he asked me for a wiring diagram of those kinds of boring machines.
Anyone who knos where to find something like that?
Thanks!
Denan

Forgot to mention, there is a switch on the machine 1-0-2 for speed changing...

Sean,
Yes, the Little Red Book is a great reference, it's a shame it is no longer published.

No need to try anymore, my colleague found something that helped him make it 3 ph 2 speed again, before I found anything.
But thanks again for all the help!
