Think of a 3-phase BLDC motor like above in the picture. L1, L2 and L3 are the armature windings and there is a rotor in the center. As you know when sequentially magnetize the armature windings with a certain phase difference, it causes to eddy currents in the rotor and it causes to move.
Armature windings are basically inductances when you think them standalone. But when you magnetize them they act like transformers since they induce current in rotor. So here is my question:
When you increase or decrease the motor load, how would it effect the armature windings inductance? For instance, would they increase in higher motor loads?
Or, the inductance remains the same but the current flow increases only?
