Torque developed by the armature of a dc motor is proportional to
(Magnetic flux per pole) x (Armature current)
Torque developed by the armature of a dc motor is proportional to (Magnetic flux per pole) x (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
