If the motor is still connected to its electrical supply and it is safe to do so switch it on and check for an odour of burning insulation and or the presence of smoke. A burnt out winding can cause a motor to run very slowly and make a unusual humming noise, if this cannot be achieved safely then make sure the motor main switch is isolated and sniff around any ventilated area of the motor to check for the smell of burning insulation.
If you have a circuit tester that will check for continuity then use this after firstly completely isolating the motor from its electrical supply and disconnecting the wiring to the input terminals. You may see and open circuit reading between the live and neutral terminals or a short circuit between one or the other terminal when the tester is connected between the terminals and the metal case of the motor, remember that a circuit tester will read resistance so try the test on the appropriate setting, example; RX10K

The motor would not start rotating. The motor will just hum and the rotor will be stationary. If you can get the rotor to start turning the motor will still run on its run winding.I have a cement mixer that has a motor with a burnt out start winding. All I have to do is turn the barrel and the motor will start turning over. Without the start winding you have a choice of which way the motor will turn. If I turn the mixer barrel the opposite direction, the barrel will turn that way until I turn the unit off.
