Marine Electrical Systems USCG Question #719 (Set 24)

Regarding an induction motor, what does the power developed by the rotor automatically adjust itself to?

Official USCG Answer & Rule Citation

Correct Answer: Option C — power required to drive the load

Induction motor rotors operate via electromagnetic induction where rotor current and induced torque automatically vary in response to mechanical shaft load changes. Thus, developed rotor power continuously matches the mechanical power demanded by the driven machinery.
