How is the full-load (rated) torque of an induction motor defined?

Correct Answer: Option D — torque developed by the motor operating at rated horsepower, speed, and frequency

Full-load torque is the specific torque developed by an induction motor when operating at its rated horsepower, speed, and frequency. It represents the design point for continuous operation, ensuring the motor maintains efficiency and thermal stability while driving the intended mechanical load under standard marine operating conditions.
