230v motor for vfd?

ok, west coast of Canada - not at all sure about your sources up there, so that 2nd motor might be the price you'll wanting - should work just fine. I use a Chinese VFD that usually runs around $110 USD range and works just fine.
 
your motor will bolt up just fine to any direct drive grinder that also uses 56C frame. you will need to get drive wheels with a 7/8" hole.
 
Ok, single phase AC can be technically set up to run variable speed, but it's usually much more cost prohibitive than a 3 phase set up, and not ideal for something like a grinder (or anything requiring relatively consistent torque across the whole speed range).
Yep, with this I'd agree. Though there are single phase ones being advertised for use in grinders
 
Fwiw,While I never worked on a Baldor SmartMotor, Every VFD I worked on will operate fine on a singlephase input.
But, might need a jumper between L2 & L3 to prevent a ”low volt” faultcode. (this example occurs on Fanuc VFD, it just needs to ”see” a voltage on all three terminals, otherwise displays powerfault)

If one understands basics of how VFDs work, its easy to realise why.
Input power simply goes thru rectifiers & that powers a single highvoltage DC bus.
Small portion this DC gets regulated down to low voltage DC to provide power to operate its microprocessor & display, etc.
The processor drives the big output transistors what take the highvoltage DC & inverting that into the variable frequency 3Ø output.

If the price is right & needed it, I would buy that motor.
Chance is extremely good it will work on singlephase.
