I started running a KBAC 27D VFD on a 10" Baldor grinder and 10" buffer setup I built recently. This KBAC-27D VFD will power up to 1.5hp 220V 3ph motors on 120V in, and will power a 2hp 220V 3ph motor on 220V in. the KBAC-29D will power 3hp 220V 3ph motor on 220V in only (no 120V option on it). These VFDs are completely sealed Nema 4x IP65 rated setups and do not require the enclosures like many cheaper VFDs do that have cooling requirements and fans. They are not cheap though - about $360 for the 27D and $380 for the 29D. Its also a VERY SIMPLE VFD to use. All settings are made with jumpers inside the door - no programming or looking up codes. It comes with one switch for start stop (not AC line off), and the potentiometer. You can wire in AC line on/Off, fwd/stop/reverse, and a start jog switch as options. I wired in fwd/stop/reverse and also the AC line on/off. I used my own cheaper DPST and DPDT switches and not their expensive options. They are just toggle switches. Anyway check out these VFDs if you want simple sealed setups without a lot of hassle.
