Checking Motor windings

I want to check the whether the windings of an AC motor is Ok or not?

What is the simplest way to do that?

Any laymen should able to understand and check on his own?
 
measure the resistance of the windings i guess?

That only checks if the windings are O/C or not, if they have shorted turns it won't be detected. To check for shorted turns you can 'ring' the coil, you can buy kits for this - actually for checking line output transformers, but they work on any reasonable coil - it will also prove if the coil is O/C as well.
 
plug it in:D :D (no don't unless it's allright)

Come on things you can do better than that.:p

How does he know if its 'allright' if hasn't been able test it?:confused:
 
What sort of AC motor is this?

Three phase?

If so then all the coils should have the same impedance.

Remove the rotor (so there's no loading) and test each coil individually by connecting it up to the output of a 24VAC transformer. Measure the current through each coil separately, you should get similar readings from each coil, if one's out by more than about 5% then I would consider re-winding it or replacing it if re-winding isn't an economically viable solution.
