From the plate, single phase 230v, 2800 RPM, 2.2kw, 12.9amps

Not the best rating plate i've ever seen......

Agree with Neil.

However, what are the symptoms? Not the described symptoms - what does it do when you try and run it? Does the motor feel like the bearings are going?

With a motor like that I'd expect it's attached to a fairly substantial compressor and I'd be much more inclined to check the oil level in the compressor head.

I did have a feeling thats what the 2.2, 2800, 230 was but as for 12.9 and the rest no idea

and did not know if you get 230volts motors that are 3 phase .....electric = magic to me lol THANK YOU you are a star

everything works .....100% its just the bearings going ..so at least i know i can price them up and wont waste money on a motor i cant run on mains power ..or more than likely cost less to buy a new motor

for it ...thank you big time
