Question:

It is not clear what the purpose of the inductance meter is to measure the motor stator windings

It is not clear what the purpose of the inductance meter is to measure the motor stator windings

Answer:

Because of the existence of the iron core, the inductance of the motor winding is larger (especially when the rotor is drawn out), so that by measuring the magnitude of its inductance, it is easy to find out whether the winding is out of order.
The number of turns of the winding inductance, because it with a square relation, it is very easy to turn a few from the inductance seen. In addition, a slight turn to turn short circuit can also be measured.
DC resistance, by contrast, is less sensitive. Because the DC resistance is too small and it is only determined by the absolute length of the coil cross section, it is not easy to spot the problem.
