NettetInductance (L): Inductance measures a coil or winding’s ability to store a magnetic field. Motors have both self-inductance and mutual inductance. Degradation of a coil’s insulation affects self-inductance, and any change in the rotor’s electrical circuit affects mutual inductance. Inductance imbalance often comes from rotor position.
