Howdy!
I'm commissioning a new-to-me wide belt sander. It's been an adventure all the way 'round, but I'm nearing the finish line. I've got one last hurdle though:
This is a two-headed machine. One head has a 17HP motor, the other is a 30HP. The 30HP motor's startup load is more than my electrical service can handle. Its oh-so-close, but it trips the breaker.
When I remove the v-belts connecting the motor to the drive drum for the sanding belt it starts up no problem, though!
I'm wondering if there's a "proven" way to get the motor spinning before engaging the sanding head, perhaps via an electromagnetic or centrifugal clutch system? Could also be other mechanisms I'm not considering... If I can separate the inrush load from the drum-start inertia load I'll probably be in clover.
The other option is, of course, to replace the 30HP motor with a smaller one, but I'm hoping to avoid that.
Oh, and this is a machine of European descent so the motor shaft is 42mm, which seems uncommon.
