How to wire motor plug

[jinsingh]

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

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

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?

When you took the cover off the motor did it have a wiring diagram inside the cover

Doesn't make much difference MW, we can see the line and neutral going into the motor, but we don't know for certain which cores of the input cable those line and neutral correspond to, as there's a switch and possibly a junction box in the middle. We can't trust that the colours going in are the same as the ones coming out to the motor as it has been altered.

Just trying to help since he came to us for help I understand what you are saying but it drives me crazy not being able to get his motor running. I’ve been on YouTube researching but you are right we can’t just assume anything

Hi

No wiring diagram anywhere at all I will second check to see if any numbers on wires. I will also open the base and see if I can check how the power wire joints the cable running to the motor

It looks from the picture that it is configured for single phase.
Presuming it’s 230v or there about, I would expect this to be a half hour job for anyone who is competent and has a good understanding of ac motors and there configuration for single phase use.
Where in Birmingham are you?
I might be passing you on Monday or Tuesday as I am working that area early week,

Hi

I am just north of Birmingham near West Bromwich

Is this for DIY, or for your business jinsingh?

 

[StephenRowley]

My guess is that some of the control need 110v hence the neutral but it has 220v motor to boot.

Hi Guys

I've managed to take photos of how the cable from the motor connects to the power cable.

It looks like the black wire is connected directly between both cables, green wire isnt used, Red and yellow wire is connected via switch.

They are useful pics. You are going to need professional help with this because the unit appears not to be earthed unless the blacks are earth, where do the blacks go. The greens appear to have been at some time connected to the switch.

Looks like the black wire is connected between cables but isnt connected at the motor see image

Have you purchased that as a brand new machine, not second hand.

 

[jinsingh]

Do you guys think this machine is self earthing? And just need to ground the chassis please see image.
