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?

A single phase 7.5HP compressor duty motor will set you back some money, but I'll bet you'll be ahead in the long run. IIRC, the single phase 7.5 motor will be around 43 amps. It's probably a "C" face motor if it bolts directly to the input of the compressor. You should be able to find one.
The nameplate information should provide the mounting style of the motor for a supplier to match it with a single phase unit. My compressor motor is only 5HP, 220VAC, 1phase and it was expensive. |
