Write the solution neatly so i can understand it.
A DC, separately excited motor is connected to a fan-type load. The armature circuit of the motor is connected to a full-wave, AC/DC SCR converter. The input voltage to the converter is 231 V (rms). The triggering angle of the converter is adjusted for a motor speed of 500 rpm. The armature current, in this case, is 18 A. The armature resistance of the motor is 0.3 N, and the field constant (Kø) is 2.1 Vs.
