A 230 V, 20 Hp, 850 RPM, 73 A DC separately-excited DC Motor has an armature resistance of 0.176 Ohm and a sufficiently large inductance such that the motor armature current can be considered ripple-free when supplied by a full-wave fully-controlled three-phase rectifier. The AC power supply is Y-connected with a 110 V/ph and 60 Hz. When the firing angle is 120,The RMS value of the third-order harmonic of the supply line current is:
