A 115VAC single phase in and 115VAC out VFD that can run capacitor start motors?


I took the cover off the capacitor so you can see it's still in the start circuit. The VFD comes into play only when the start winding drops out, so you can't run a capacitor start motor at less then thirty some cycles. But this gives you some speed control of things like single phase fans that run air handling systems.
