For a given torque, reducing diverter resistance of a dc series motor
Increases its speed demanding more armature current decreases its speed demanding less armature current
For a given torque, reducing diverter resistance of a dc series motor increases its speed demanding more armature current decreases its speed demanding less armature current.
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
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
