I think the first thing you should do is carry out an insulation test upon the motor. Test the windings to earth, not winding to winding. Use 250 volts only.

You can test "winding to winding" but if the insulation is already damaged, this test may cause even more damage.
If it's an old motor, your best option is to take it to a motor rewinder & have them test it for you.
