The increased current flow in the primary or stator circuit of an AC induction motor during start-up or under locked-rotor conditions will not reach short-circuit or fault-level overcurrent magnitudes as it would with a secondary-shorted power transformer because of the higher motor impedance.
Many factors, such as the type of winding, type of conductor, length of the conductor, and the width of the air gap between the rotor surface and the stator pole faces, contribute to the overall impedance of an electric motor.
A) True
