All of the above
The main disadvantages of the Ward Leonard system are High initial cost, Poor overall efficiency and High maintenance cost.
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
