Technical Notes and Corrections
1. The VFD is a single phase to three phase VFD. It creates the other phases, and controls the speed.
2. Several people have left this video and immediately searched for a single phase VFD. I think they mistakenly thought I was saying this item doesn't exist. But the point was only that they are rare for a reason. They are only safe to use with a few special types of single phase induction motors without start windings that must be disconnected. The "rareness" of the motor makes the controller rare. They certainly exist, but you should not use them with the typical induction motor described in the video.
