Residual magnetism of the generator
In Ward-Leonard system, the lower limit of speed is imposed by Residual magnetism of the generator.
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
