would this motor work for a disk grinder? if so what VFD would you recommend? is this motor reversible? I do have 220V available so that isn't a problem. any help with this would be greatly appreciated. thanks in advance

Three phase motors are reversible. Any 1Hp rated VFD that takes 110/220 VAC single phase input will work fine. That is a good disc grinder motor.
 
Awesome! That was what I was hoping. I scored a great deal on it and hoped it would work. Thanks for reply. This forum is the best resource out there as far as I am concerned
 
The only problem I see is a 143tc size motor has a .875" shaft. I'm not sure if anybody makes a disk for that shaft size.

What about this one? I know very little about motors. This does not appear to be a c face motor but the specs look good.
 
I believe that motor has a threaded hole in the end of the shaft and would not work as the shaft does not have a key way.
 
Ok.....I am striking out here......might have to go back to the drawing board. Thanks though... Or I might have to buy disc system and have hub bored out if it wasn't to expensive and didn't damage the integrity of the hub system.
 
You might check with the manufacturer to see if you could get the disc(s) bored for your shaft. It might cost a little more but probably less than farming it out when you get it. I seem to remember a forum member who made up some of these discs for sale.
 
I thought I had seen a few suppliers who offered a 7/8" shaft disc ( .875"), but can't remember who it was. A machine shop might be able to bore out a 5/8" disc and true it up.
 
Should be no prob for a competent machine shop. Then, you may have to have it re-keyed, and will incur a little added cost for the broach work.
I would bet if you order one from Beaumont, Rob would easily bore it to 7/8" for you.
 
I have a disc that uses a 7/8 motor and I like it much more than the 5/8. Very stable and stout. It would be worth having the disc bored out. Plus you can find those odd motors really cheap. That first one looked like a hazardous duty motor. That would be perfect for a disc in a dusty shop.
 
Maybe you need to go the other way...................... Make (or find, maybe these are already available put there) a keyed adapter to downsize things from .875 to .625. Just a thought.

I did this once upon a time and it worked like a charm

I was thinking the Rob was the one who offered it in both sizes. Check with Beaumont. His discs are superb.

I don't remember that.

I do remember Nathan The Machinist was asked to do some in alternate sizes and he sounded agreeable.
