Q.

A separately excited dc generator is feeding a dc shunt motor. If the load torque on the motor is halved approximately 

  • AArmature current of both motor and generator are halved 
  • BArmature current of motor is halved and that of the generator is unaltered
  • CArmature current of generator is halved and that of motor is unaltered
  • DArmature current of both motor and generator are unaltered 
Correct Answer : (A)

Armature current of both motor and generator are halved 

Hints :

A separately excited dc generator is feeding a dc shunt motor. If the load torque on the motor is halved approximately, then the Armature current of both motor and generator are halved.

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
