I have built a vibratory tumbler that uses a 1/4 HP 1725 RPM 110V motor (probably a surplus furnace motor I had laying around... can't remember for sure). Anyways, the unit works great, and I am going to build two more vib. tubs.
I have been using VFD's for alot of things like my lathe, and even a large air cannon fan I scooped for a good deal and when I look at the vib tumbler, it would be neat to have the ability to vary the speed to change the tumbling aggressiveness.
So... I was thinking that on the next tumblers I build, I would try a VFD. One of my questions is: Can I run a couple of motors off of one VFD? I realize they would run the same speed, but is there any reason this would not work? As long as the VFD was sized properly, such as using a 2HP VFD with a couple of
1/4 HP 3 phase motors operating separate tumblers?thanks, ron
