Looking at the specs for a 20hp American Rotary and North American Rotary; the PL-20 is advertised having an idle amperage of 7.37 and $.14/hr and the ADX20 having idle amps at 2.48 or 0.06kW and $0.06/hr. Is American Rotary doctoring their numbers? Even so any idea if one is much more efficient or better than the other?
Lots of phase converter threads here and I've read a lot of them but if anyone has any comments on my plan feel free to chime in. I have a 2016 size Dyna Mechronics machining center with a 7.5hp spindle and a Fadal 4020HT coming. The shop has 200A panel of single phase power. For now I plan on buying used ADX or PL on ebay or buying one of their DIY panels new and getting a used motor locally for an idler. For now I'm thinking a ~ 20hp RPC for both (not at the same time), the Fadal of course with a 22hp spindle I will have to baby on limited power. In the future I'd leave the 20hp RCP on the 2016 and get a ~40hp RCP for the Fadal or a ~25hp Phase Perfect.
