The speed of a dc shunt motor supplying a load at its rated speed can be reduced by
Connecting an additional resistance in the armature circuit
The speed of a dc shunt motor supplying a load at its rated speed can be reduced by Connecting an additional resistance in the armature circuit.
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
