In a Ward Leonard drive, if the filed current of the dc generator is suddenly reduced, the controlled dc motor operates
In regenerative braking mode
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
