Which of the following statements describes what will occur if the motor torque-speed and current-speed curves shown in the illustration is required to carry 150% of full load? Illustration EL-0056

Correct Answer: Option D — The stator current will increase.

Operating a motor at 150% of its rated load requires higher electromagnetic torque to overcome the increased mechanical resistance. Per fundamental induction motor theory, this increased load necessitates higher stator current to maintain the required flux and torque, resulting in increased slip and higher current draw from the supply.
