A series motor is working drawing a load current of 1A from the line if now the load is reduced such that the current drawn is halved, the speed of the machine (neglecting the saturation and armature resistance) would be
increased by 100%
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
