Tech director for performing arts facility, helping out with high school production using a revolve. Rented 20' wood framed (very nice) 20' diameter revolve. Trying to resurrect a drive that a coworker and I fabricated 20 years ago. 3 phase, 1/2 HP 208-220V Dayton AC drive motor coupled with a Dayton speed reducer to a pneumatic rubber wheel. Newer facility that has a 120/208V 3 Phase 4 wire safety switch that has never been used - no fuses or feeder cable/distro plugs - installed on upstage wall. I am looking to install a Variable Frequency Drive so I can control direction, acceleration and speed. I have access to a 220V powered VFD that I could feed from a (very) remote panel, or I could purchase a new VFD to run from this safety switch. Any reason to choose one over the other? Basically wondering if there are any advantages to sticking with 3 phase input to VFD versus using the VFD to adapt from 220V to 3 phase power.
