How Does a Rotary Phase Converter Make 3 Phase from Single Phase?

If you power a three phase motor with single phase, then once you get it rotating, it will continue to rotate and generate the third leg of power for three phase applications.  This is the principle behind rotary phase converters.

In this video we start explaining how a rotary phase converter actually works and the purpose of the start and run capacitors.
