DC Motors If a D.C. shunt motor is working at no load and if shunt field circuit suddenly opens This will make armature to take heavy current, possibly burning it Nothing will happen to the motor Motor will run at very slow speed This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses This will make armature to take heavy current, possibly burning it Nothing will happen to the motor Motor will run at very slow speed This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses ANSWER DOWNLOAD EXAMIANS APP
