Marine Electrical Systems USCG Question #38 (Set 2)

What is the characteristic of an wound rotor induction motor with maximum rheostat resistance inserted in the rotor circuit during starting?

Official USCG Answer & Rule Citation

Correct Answer: Option B — relatively high starting torque and low stator current

Maximum rheostat resistance in the rotor circuit during startup improves the rotor power factor and drops starting current while delivering maximum starting torque, adhering to IEEE 45 motor design parameters.
