Hey Everybody,
I posted this over on owwm just a bit ago thinking it pertained to that site, but want to get as much feedback as possible, and I think there’s more traffic here. I try not to make duplicate posts on different message boards, but here goes:
Interested in feedback from others that are running large bandsaws off rotary phase converters or vfd’s. Recently moved shops and lost utility company three phase and am running my equipment off an American Rotary ADX 20 hp. My Tannewitz GH36 has a five hp direct drive motor, but it pulls a ton of amps on startup and I keep tripping breakers. My electrician buddy suggests I buy and wire it with a 80 amp breaker to handle startup, but the breaker alone is close to $500 (local supply store price, can likely get much cheaper online) and I feel like it’s somewhat of a shot in the dark if that will improve the startup issue. Is anyone out there running this saw off a vfd with success? Would you suggest I follow the advice of my electrician? Curious what others are doing with large bandsaws that are lacking three phase from the street. Thanks
John
