I have a 7.5 HP vane type compressor that I am researching how to run on single phase power. Swapping to a single phase motor is not an option. Anyone have any knowledge of sizing a phase converter? It looks like I can find rotary phase converters that say 7.5 HP for around $600. But I don't know if this is one of those situations where I really should be getting a 10 HP converter for the 'extra overhead power'. Advice?

Static phase converters are not a GOOD option for a compressor... PERIOD...!!!!!!!!!!!!!!!!
Especially if the compressor head bleed valve is a tad sticky. That will smoke a Static converter AND the motor very quickly. (ask me how I know) The statics are great for anything other than a HARD starting piece "O" machinery like a compressor or a big mill. Why is a single phase motor not an option? I am guessing you have a wire size or breaker/panel threshold that doesn't allow you to use a single phase 220 motor..... Corrrect? C |
