And then there was the advanced setup ..... Charlie knows his stuff ;

My NWG is complete...less a working motor, thus asking about a more affordable supplier. Charlie' s creations in the workshop are indeed amazing, he can belongs on the A-Team! Unless someone can point me to a cheaper supplier, i will order from the supplier i listed above.

Have you looked at Graingers ? There is usually one not to far away from most industrial areas and they have EVERYTHING !

Search 3 phase, 2hp motor with 7/8 shaft - Grainger Industrial Supply

Second thought....after seeing prices I would suggest the same thing as Pixel. You might even get a motor attached to a lathe or something at that price..

Ya, grainger does have pretty much everything &a you pay thru the nose for it.

Seems like your options are slim and none,maybe sell the grinder sans motor.

Craigslist > Cities

This is a 4 hp 220 single phase $100
4 HP Electric Motor

Second one on this list seems to be what you want

Now you see the usefulness of craigslist.org

Hope this helps

NOW you post...i have a new motor on the way. Just over $300 shipped, the salesman was most helpful. I didnt realize most motors cant handle a vfd for long. This one can run down to 1/10th of the 1800 rpms continous.

Assuming we are talking about 3 phase motors I don't understand that most can't handle a VFD for long. Other than shaft voltage possibly effecting bearings and that for your use and size of motor needed should be no problem. If anything it should extend their life. At work we don't run anything under 20 Htz.
