The single-phase motor generally has a DC resistance greater than that of the running winding. The simplest method of discriminating is: 1. First measure the DC resistance of the common terminal to the running winding end and the starting winding end with a multimeter.
2. Then use a multimeter to measure the DC resistance from the running winding end to the starting winding end.
3. If the arithmetic sum of the two measurements in "1" is not equal to the measured value in "2", then the motor must be burned!
If they are equal, it is best to compare them with the same type of motor, or find the factory parameters of the motor for comparison. To judge the quality of the motor.
Disconnect the capacitor when measuring a single-phase motor. Single-phase motor short-circuit is that you have to have a normal resistance as a reference.
