My compressor has a 5HP 3-phase motor. All I have is single phase 240V. The pump and motor are both 100% duty cycle. Anyway, the motor is in good shape, just needs new bearings. Should I buy a VFD and run the motor I have? My other option would be getting a 5HP 1750RPM 1PH motor and a new pulley (current motor has a 1-1/4" shaft). I like the idea of being able to program a VFD to soft start or vary the speed. The spec sheet for the pump lists different operating RPM depending on what HP motor it was packaged with - 3HP, 5HP, or 7-1/2HP, so I wouldn't be hurting anything by running the pump a bit slower or a bit faster. I think the RPM range was from around 400 to 800-ish. Swapping to a 1PH motor would be more simple, but I'd loose the extra bit of control that comes with using a VFD and I doubt I'd find a motor built as well as the one I have for a reasonable price. Thoughts?
