How to wire motor plug

[Spoon]

Hi Megawatt

I only have the image and details from the advert. It was purchased via Aliexpress which is a Chinese wholesale website.

Where did you get the pic of the 4 wires? (Your original pic). That doesn't look like it's from an advert.

It looks like a US dual phase lead, (what they call 3 wire) though the yellow wire should be white and should not be connected anyway.

Thanks jingsing I’ll see what I can come with and advise you

If possible can you remove the motor terminal cover and show the connections within.

Hi will try and open motor and take some photos

Sorry I searched that from the Internet

This may be a stupid question, but if we assume the cable could be wired to an American 4 Pin plug, could it be wired the same way on a UK plug but ignoring the green (ground)??

No, we don't use that type of power in the UK, it's specifically N. American. I think the references to US power configs here are misleading, there's no reason to think your machine is wired that way. The Chinese 3-phase colours are red/yellow/green which matches your cable (although I think neutral is more often blue now). I suspect one of two things:

a) they sent you a 3-phase machine instead of the single-phase one you ordered.

b) they converted it to single-phase but left the 3-phase mains cable attached.

Either way, they shouldn't sell equipment in the UK with that cable.

We need to see:
1) Motor rating plate
2) Inside motor terminal box
3) Where the cable terminates inside.

Hi everyone

I am really grateful for all your time and help. Please find attached photos of the motor, wiring, and back of the machine.

Hope it make sense to you guys.

I assume the flex terminates elsewhere.

It’s not 3 phase or the third pole has no jumper and the yellow makes since it has a capacitor in it

 

[westward10]

Agreed the capacitors weren't clear from the first pic. Cap start and run.

Hi

So is the motor single phase? Does that help with how the plug should be wired?

this site is not going to let me help you go to you tube and look up 220 single phase motors

Does the wires have numbers on them

 

[Megawatt]

Are there numbers on the wires

OK, the motor is definitely single phase, but they have left the original 3-phase cable with chinese colours attached. You will need to inspect where the cable terminates, and possibly make some continuity measurements with a multimeter, to find out which colours they have used for line, neutral and earth as it's now impossible to assume anything. In fact it would make more sense to replace the cable to the input terminals as the existing one is totally unrecognised in the UK.

In truth, now would be a good time to call an expert to look at it. Or even call the supplier, although I am not sure whether you will get an intelligible answer that way! However, if you're up for more investigation, do you have a multimeter and are you familiar with using it to take resistance measurements?
