Hi Guys,
I've recently had a bit of a score on an air compressor. I picked up a 100L "Clarke" brand air compressor (This one, to be precise: www.ebay.co.uk/itm/Air-compressor-/221150743120 ) with a 3 phase Ceccato 5233 or 80/4 motor. I'm having problems getting it going and was hoping you could help me trouble shoot. I'll let you know what I know.
The bloke I got it off said he had a mate of his "convert" it to run on 240V about 10 years ago (the front on the inverter has a date in '01 written on it) and said it was working fine when I stopped using it about 6 years ago. I've got no reason not to believe him but at the same time... I don't necessarily believe him.
There is a an "IMO JAGUAR CUB VC75" variable frequency inverter attached to the compressor which is all wired up. When you plug it into a 220v supply you get the power light come on. When you press the run button on the air cut off solenoid box thingy; the run light comes on the inverter but the motor doesn't turn or buzz or anything. If you put a multimeter over the output pins when it's on, you get 0 however a bit further up there's some connection for the DC Brake control which there is power at.
I've found this user manual for the inverter: http://www.denfordata.com/bb/download/file.php?id=1275
This is the faceplate data card:
So we know somewhere the inverter is toast, HOWEVER on the motor cover plate, it seems to note that the motor can be ran in either single or 3 phase modes. Here's the cover plate:
From what I can make out; ROTAZ DX means rotate clockwise and ROTAZ SX means rotate anti-clockwise (or vice-versa). We've connected a power supply straight up to the motor to see if that will make it run (we've tried both configurations) but all you get is a nice humming noise. I seem to remember reading somewhere that you'd probably need a starter capacitor in order to get a motor this size running. Does that sound about right? Where does that go in the grand scheme of things?
Is it worth trying to get it running on single phase or just try and find a new inverter?
I think that's everything but please ask any questions you may have!
This is the motor's cover plate (frontal view).

Many thanks in advance!
