More like a chunk collector - hahahaI guess it has a jury-rigged dust collector on it.
Dust collection is... mandatory.
3-phase? In my experience smaller motors are all single phase or pseudo 2-phase (capacitor run) 3-phase is usually 220v or greater...Be aware that VFD's must be EXACTLY matched to a particular motor, so while you can find an old 3-phase fridge or washing machine motor for cheap, the same is not true for an old VFD unless you have nothing better to do for the next ten years than search and wait for the right one to pop up on Craigslist.
His teeth sufficed for a number of years.Jimmy Cooke says dust collection is for pussies.
Once upon a time yes, but there are loads of single phase VFD’s on the market now. What you can’t do is use a VFD on a 110/120 only motor. It needs to be a 240vac single phase. They even make single phase motors that are especially designed to be used with VFD’s. But in my opinion a DC servo is a better option for on tap speed control. You can harvest these for cheap from old treadmills along with their speed controls, but it takes some crafty lathe work to make an arbor for em.VFDs only work for 3-phase motors.
Once upon a time yes, ...
The Europeans have been using single phase (400vac) VFD’s since the 80’s. They only became popular in North America about 10years ago. They work pretty well but they do have a relatively short life expectancy in an industrial setting. There’s even a few VFD’s on the market that will run a delta motor on a 120vac primary, but they’re not optimal.This is how you know you're gettin' old.
