Starting of 3-Phase Induction Motors The induction motor is fundamentally a transformer in which the stator is the primary and the rotor is short-circuited secondary. At starting, the voltage induced in the induction motor rotor is maximum (Q s 1). Since the rotor impedance is low, the rotor current is excessively large.
