When you unsplice the run windings(they will be connected in parallel) do keep track of which wires paired up.joshh wrote:I sent you a PM with my address. This is the first one I'm converting to 230V (though it shouldn't be that different so I'll post an update once I'm in it and have JPG check it before I fire it up
I do plan on making the voltage externally selectable.
Very true, only 120 VAC for the start windings. If you get any phases backward for any combination of input voltages and coil winding hookups, you will most likely get an electrical lockup on the rotor. This is quite noisy and loud so you will notice it immediately to stop appling power.JPG40504 wrote:When you unsplice the run windings(they will be connected in parallel) do keep track of which wires paired up.
When connecting for 120V, they need to be paired up the same.
When connecting for 230V, they need to be 'phased' the same(If originally spliced Aa and Bb(AB is one coil, ab is the other), then a connects to B and 230v is applied across A and b.
I cannot check that you have done this correctly 'after the fact'.
Also the start circuit will only be connected across one of the run windings(the start circuit will still be a 120V circuit).

Yes, this is a standard NEMA motor wiring diagram that I use when rewiring motors:joshh wrote:So, what color wires do y'all recommend using? I assume there is some standard.
Thanks JPG40504. I really appreciate you keeping track of my posts and filling in more details when I post responses. Many times, actions that are second nature to me may not get covered in some of my responses. I am trying to do the "Paul Harvey" type responses lately but can still be missing some important details. My memory is slowly disappearing now so I really do need this additional attention. 90% of the material in my responses are from my thousands of computer files and pictures that I had saved in recent years. My poor naming of some of these files and pictures makes collection information together on a specific subject difficult for me at times.
