I have been thinking a lot lately with developing a new sharpening routine for planes, chisels, and such lately, looking at the Tormek, Proedge, Worksharp, Rikon with CBN, etc. I have been kind of obsessed with Baldor grinders…long and short, I bought a grinder that I think is a Baldor today. Its a 10”, but the name plate is gone. From my internet research, it looks like a 1021W. My plan is to put a VFD on the grinder, and go from there. I am hoping it works. If it does, then I am going to figure out some type of wheels, maybe CBN, maybe a belt sander attachment, maybe a buffing wheel…but thats all getting ahead of myself.
My first question is, can I assume this a 3 phase motor? There are 9 wires coming out from the motor, labelled 1-9. If so, do you have a recommendation for a VFD which would give me variable speed? Seems like there are 2hp, no name units on amazon and ebay. Brands that I recognize start at $200 or so. Thanks for your help.
