I did buy the single phase powered ABB drive it should be here next week.
Along with that 4 pole motor.
Looks like the go-cart clutch will be here first thing next week. I'm going test putting it on my 2.5hp 2 pole compressor first. If it helps soften start up current I will adapt it to 4 pole motor use.
So I'll have a 4 pole 1.5hp compressor on a VFD, a 1hp 4 pole motor with a go-cart clutch and a 2hp 4 pole compressor with a electromagnetic clutch.
My prediction is the go-cart clutch will give you the most bang for you buck as far as taming violent startup inrush current. The best thing overall thing you can do is is stick with 4 pole motors.
I will test the magnetic clutch against the go-cart clutch, if the go-cart clutch is better I will abandon the magnetic clutch idea and resell it on ebay.
