I think most people looking at idler rotary converters dont actually scope the phases I only came across one site stating the obvious
given the basic diagram of 120 ac to motor P1 and output phase L1 neutral--nc 120 ac to motor P3 and output phase L3 Capacitor P1 to P2 and to output phase L2 will notice the 180 deg phase of the two 120 lines are connected directly to L1 and L3 so that is at 180 degrees not the 120 it should be. So L2 is some where in between L1,L3 but if it was 120 degrees from L1 then it would be 60 from L3 the voltage imbalance would be silly so it is adjusted to be 90 form L1 and it just about works Now after that point there is a 3 phase transformer, one may think that helps the phasing but I am not so sure, a friend at a transformer company said many years ago that there is no such thing as a three phase transformer, it is really 3 single phase transformers.
