I'm slowly collecting material and parts to build a 2 x 72 belt grinder. I have a 3 hp 3 phase inverter duty motor to use and I'm looking at VFD's. I see a lot of diy and commercial units use the KB VFD's since they are simple to setup and in sealed enclosures. Their 3 hp unit, KBAC-29, is only rated at 3 hp with 3 phase input. I will be running single phase input which they only rate the VFD at 2 hp. I have a Hitachi WJ-200 on the 3 hp motor on my lathe and it works great. The Hitachi is less expensive than the KB but it would need an enclosure and I assume venting which is not desirable for the environment of a grinder. I also don't want a huge enclosure either. Any thoughts on a suitable VFD and/or enclosure or just taking a chance on the KB unit?
