A dc, separately excited motor is rated at 10 hp and 300 V. The rotor resistance of the motor is 1 ?, with an inductance of 30 mH. The field constant (K?) of the motor is 4 Vs. The inertia of the entire system is 1 Nm sec2 , and the load torque is constant and equal to 50 Nm. The motor rotates at 1500 rpm. If the voltage of the motor is reduced to 200 V, compute the new steady-state speed. Also, plot the speed of the motor as a function of time during the transition.
