If the motor is driving a load whose torque requirement


Consider a permanent magnet dc motor with the following parameters; Ra = 0.35 ohms, La = 1.5 mH, Ke= 0.5(V/(rad/s)), Kt= 0.5 Nm/A and Jm = 0.02kgm^2. The rated torque of this motor is 4Nm. If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
