Q.

A DC Shunt motor may have rising speed torque characteristic due to

  • AVery high armature circuit resistance
  • BVery high filed circuit resistance
  • CVery high demagnetizing armature reaction
  • DVery low demagnetizing armature reaction 
Correct Answer : (C)

Very high demagnetizing armature reaction

Hints :

A DC Shunt motor may have rising speed torque characteristic due to Very high demagnetizing armature reaction.

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
