Hi guys. Tnx for letting me ask a dumb question here. I'm retired from electronics all my life but this is a theory question. My brother bought a 3 H.P. -240 ac motor from Grizzly.com to run a bandsaw with. He bought the first one he came to that had the right shaft size. When he got home he immediately welded on a different base (which would void any warranty) and then he wired it up only to find it ran the wrong direction. The grizzly model number is H5387 and only had two wires exiting motor. The book says it is non-reversing. I'm thinking that is because there is no block inside with all the wires terminating on it, most of all others made by same company will reverse. Detective work has led me to find out that it is a Capacitor start-Capacitor run motor with the start switch only cutting out the start capacitor and leaving in the run capacitor (parallel run cap with start cap & switch). QUESTION: If I physically swap connections from start & run circuitry by inverting connections - will it reverse rotation ? I would have to open up wire terminations to do this and can, but I want to be sure it will reverse. Otherwise for him it will be cutting up his band saw and sticking the motor out the side.....Tnx to all for your help.
