Hello,
I don't know much about wiring of electric motors etc so I thought I would post here and see what wisdom I get.
I have a ~1963 Colchester Dominion 13x36" lathe that was working 100% fine until about 10min ago. I have a dial/rotary switch in the main casting for Off-Forward-Off-Reverse (closewise). The motor is a 3hp single phase 230V (North America power - Canada).
What happened: I wasn't paying attention and switched it from forward to off (the motor clicked off as usual) but I must have not hit a 'notch' in the dial as it then started to go in reverse. I clicked it back to Off on the dial and thought nothing of it while I changed tooling. I the turned it on to forward and all it would do is humm. Turned it off (no click from motor) and tried reverse (just to see). It rotated the spindle at about 1/10 speed then the breaker went. Now all it does is humm or/and click the breaker.
It's a PITA to get to the motor/wiring as I have things right now so I am not going to look at it until tomorrow but I have a bunch of work I would REALLY like to get done on the lathe (wife away for weekend so I have all the time to work on projects! :))
Anyone have any ideas what I should look at/for when I get in there tomorrow?! I assume there is something in the box on the side of the motor I need to look at?!
Thanks, Jeff
