Definitions:

Impedance

The total opposition that a circuit offers to the flow of alternating current, combining resistance and reactance.

Hysteresis

The phenomenon in which the value of a physical property lags behind changes in the effect causing it, often observed in magnetic materials where the magnetic flux density trails the magnetic field strength.

Inductive

Pertaining to inductance or exhibiting properties of inductance, which is the property of an electric conductor or circuit that causes a change in current flow.

Rotor Stalled

A condition in which the rotor of an electric motor or generator fails to rotate due to excessive load or insufficient power.
