Old Bandsaw Electrical Question Help!
Electrical question folks. I have an old Davis and Wells bandsaw. Looks like original motor, switch. When I bought it there was a variable speed drive hooked up so it would run on 220. The variable speed died, and I have 3-phase at the shop.
I ordered a new plug and wiring from McMaster to run it on 3-phase. Everything worked just fine. Saw ran fine for about 5 minutes. Went to turn it back on, just a hum. Opened the switch and now it’s sparking here (see image). Motor won’t run.
Waited a while, turned it back on, and it ran.
