I need help with electric motor

I have single phase 220V AC electric motor that I need to connect to power supply, maybe is missing some bridge between contacts.
What is wire that goes between electric motor and fan
Why is 60Hz, where I live is 50Hz is it ok to use 60Hz single phase 220V AC
There is continuity between 1,2,3

resistance between
1-2 18,8 Ohm
1-3 35,5 Ohm
2-3 17 Ohm
4-5 there is nothing

Thanks for any help

That could just be a shaded pole motor for a fan, if so presumably it takes 220v and maybe fed from internal connections.
Do you have the 7Uf capacitor needed for the start winding which could be the 35.5ohm winding and wired in series with it, the run winding will be one of the low resistance ones of the two, the other could be the fan itself, you maybe need to try and identify which of the two 18.8 or 17 is the fan.
If you need to obtain a capacitor, ensure it is motor start rated type.

The gizmo behind the fan might be a speed feedback generator.

I remove fan to see what it is see pictures
With motor didn't come capacitor but I have 10Uf capacitor can I use 10Uf capacitor
A is connected with 4
B is connected with 5


only left 1,2,3

There is continuity between 1,2,3 is motor bad if there is continuity between 1,2,3

resistance between
1-2 18,8 Ohm
1-3 35,5 Ohm
2-3 17 Ohm

You cannot use a general purpose electrolytic, it has to be motor run rated, oil filled paper etc.
So the A and B does seem to be a sensor and not used at this stage.
There does not appear to be the normal difference between start and run winding's, but the lower resistance winding would be the Run and connected across the supply, the other would be the higher Resistance and connected across the supply with the capacitor in series.
The highest reading is usually both run/start in series.
Edit: just realized it is only a 1amp motor so it is most likely a PSC motor where the start and run windings are identical, so you can use either as a start or run to achieve either direction.

No AC will be in on A-B or B-C the series cap to the either of the other two.
You can use a SPDT switch for either direction and OFF.
L1 can go to either R or S.
You should get away with a 10uf.

Monitor the temp for a while, if it doesnt like the 10u it'll get warm.
Glad to see you sussed it.
