    You would need a three phase motor to hook the vfd to, a single phase motor would not work.

    As far as DC, If you found the correct size and spec motor to fit, you can get a dc speed controller for 170

    I run my disc grinder/ buffer combo on the above controller and it works fine.

    That would be cool, thanks

    I got the same math, I'd like to get it own to about 800 sfpm, but thank you for looking that up for me.

    I use the lower model of that controller (the red one) with my craftsman buffer. It works pretty well.
