I really need some help/advice here Gents.
I’ve posted a few pics of the switch, plug, and motor to my Unisaw (model 34-459). I bought the saw used over the summer for $500.00 and the guy that sold it to me said he ran it on 220V. I’ve been working on getting my shop together and have been using the Uni for a few small shop related projects, but run time has been pretty limited, but it seemed to run just fine. Well, tonight it quit running. I was thinking maybe a bad switch so I took the cover off the switch and all looked ok. So I put the cover back on the switch and hit the ON button. The quickly quit and the switch began to smoke so I unplugged the saw and began taking a closer look at things. Before the switch began to smoke, I tried to re-start the saw, and a couple of times it would start, but only for a half second or so, then would shut off again. Last attempt is when smoke came from the switch.
Please be aware I know next to nothing about elec. motors, switches, phase 1, 3, etc. But looking at the switch it looks awful busy for a run of the mill on/off switch. Tag on the saw says it’s a 3 phase motor but because the seller told me he had run it on 220v, I thought the motor had been swapped out for a single phase…. maybe not? Also, the tag/info on the switch looks like its giving specs for 3 phase wiring. And the tag on the motor is missing so I can’t get any info there.
Can anyone tell me what I have under the hood here for a motor?
Thanks in advance!!
