The armature circuit of the motor is connected to a full-wave, ac/dc SCR converter. The input voltage to the converter is 300 V (rms). The armature resistance of the motor is 0.5 ?, and the field constant (K?) is 2.5 Vs. Assume that the armature current is always continuous. Calculate the range of the triggering angle to operate the motor at a speed range of 0 to 600 rpm.
A dc, separately excited motor is driving a load torque composed of two
components as given in the equation.
