A 300V DC motor is running at 1600rpm taking a current of 40A. The armature reisistance is 0.5Ω. Due to a change in the magnetic field, the flux in the machine is reduced to 80% of the original value. Calculate the new speed of the motor due to this flux weakening. Also, calculate original torque and torque due to flux weakening.
