Could someone interpret the plate on this motor?
I had my eye on this surface grinder, but someone else bought it. I want to know what the plate means in case I see a similar one in the future.
Thanks.
Also, since there is no mention of phase, does this imply that it is single phase and not 3 phase?
Hey Al,
How about posting the whole Ebay (or ???) number so we can have a look at all the info and pix. It looks to me that the one pix you showed is just the data-plate for the magnetic chuck, and that it wants
440VAC supply, and produces up to 200VDC to apply a selectable force on the magnet.Take care.

DC is used for the mag chuck. AC runs the motor. More than likely it is a
3-phase machine. Three-phase is generally used on quality surface grinders because it provides smoother "power" and a better texture on the ground surface.It didn't occur to me that the magnetic chuck would use DC, but now that you mention it, it makes perfect sense. Thanks.
Here is the item in case anyone is curous:
An electric chuck will often remain magnitized after the DC is turned off. Or retain some significat magnetic properties. Many chucks are set up so you may give it a quick shot of AC to provide a built in Demagnitizer.
