Be interested as to how you wired this is, following my purchase of a second static converterSo it's a static converter then, nothing unique about it. The motor may run a name plate amps but does it produce the same starting torque?
Here's my covered showing real time volts on all phases and current draw.....

This was while testing it after a few modifications.
Its nothing fancy, just has a idler motor connected in parallel with the output. This runs continuously like a rotary phase converter. The V/A meters are on the main output so I can check all phases are balanced.Be interested as to how you wired this is, following my purchase of a second static converter
Hi Collin,, Long time no talk, hope all is going well for you. Jim Kennedy here from Australia. Just browsing the internet last night and saw you and your transformer getting some attention.
I would like to raise a few points.
I am a supporter of this method for some applications.
This method requires Transformer, motor, and run capacitor.
120 degree and 180 degree phase angles do not come into this discussion.
When motor was manufactured, slots were positioned to put windings 120 degrees apart, so we can't change that even if we wanted to.
The manufactured phase, is the motors Back EMF.
This is the same in a rotary.
This method, motor can run at full name plate Amps (So No De-rating).
A long time ago I bought the package from Unique 3phase, I think about $23 Aust. I have built many of these converters, about 5 years ago I saw a revised book from Unique 3phase and it was the best by far literature on running 3 phase motors on single phase I have ever read. I definately recommend this book.
I will give a practical example of this method.
Let's say we had a 10hp or 15hp Air compressor to run, a VFD would be very expensive and remembering VFD aren't the best for recipricating Air Compressor duty to start with./ But this transformer method is an excellent method for this application.
