Question:

Is the inductance of the stator winding of single phase ac motor constant?

Is the inductance of the stator winding of single phase ac motor constant? Does the inductance of the stator winding change when the motor turns?

Answer:

The size of the coil inductance and itself by the size of the density of field lines, when the motor rotates the lines of magnetic force density was in a cyclical change, so the stator coil inductance also followed in periodically change.
100 millihenry's inductive coils are everywhere! The stator coil of an electric motor is an ac electromagnet with inherent inductance. Its relationship to the rotor is similar to that of transformer. The resistance of the stator coil, the strength of the magnetic induction, the rotation speed of alternating magnetic field and the voltage of alternating current. Current! Frequency! The inductance of oneself has relation! The rotor of the motor can change the electromagnetic strength of the stator. Just like the secondary coils of a transformer!
This is a conceptual error! Inductance is the fixed index of inductance element! Like resistors of resistance! Capacitance value! The inductance is not inductive! Not electromagnetic induction strength! It doesn't change when it's fixed! The inductance is the design data! Inductive and inductive strength is the actual application data!
