The other thought would be to add another phase converter or use a larger
idler motor. I read on the GWM phase converter site that ePact motors on
compressors may not work very well with rotary phase converters and may
require a 4X idler size. I even thought of using 3 separate identical phase
converters with the generated leg going to a different terminal on the
compressor. But this sound like a lot of complicated contraptions.


You can try a larger idler very easily. Instead of using a larger one,
just add a second one in parallel. If you have another three phase
machine, all you have to do is turn it on (idling...) and see if this
helps your compressor start.
