  • CWeak field 
  • DNone of these
Correct Answer : (A)

Compensator 

Hints :

A large dc shunt motor can be started preferably using a Compensator.

Previous

A dc shunt motor is driving a constant torque load with normal excitation. If the filed current is halved then the motor will run at 

Next

A dc shunt motor is driving a mechanical load at rated voltage with normal excitation. If the load torque is increased to double of the normal one, the speed of the motor will
