How to Build a Rotary Phase Converter

[Frank S]

Bob you should be able to get some indication of how well it will respond to balance loading if you have a way to use additive resistance loading to any 2 of the output legs. Spin up load L1 & L2 take a reading of voltage for both legs and amperage draw then connect L1 & L3 the false leg to the same load take readings then repeat for L2 & L3 By the time you have completed the balancing you may find that you will even have capacitors across L1 & L2 to balance the incoming line voltages due to imbalanced loading elsewhere through out your supply IE the refrigerator starting up or someone using a Hair dryer.
I'm waiting for the 3rd educational video the first 2 were very explanatory as long as you said not viewing them from a physics or engineer nerd's eyes
