The torque-speed and current-speed curves for a three-phase induction motor with a squirrel cage rotor are shown in figures "A" and "B" of the illustration. Which of the following statements is true concerning the depicted curves? EL-0056

Correct Answer: Option C — Starting current is approximately 4.75 times the normal full load current value.

Standard NEMA design squirrel-cage induction motors exhibit high inrush starting currents typically between 4.5 and 6 times normal full-load current due to low standstill rotor impedance, verified by standard marine electrical testing.
