A 300 V, dc separately excited motor drives a conveyor belt (constant torque). The armature resistance of the motor is 1 ?. When the conveyor belt is loaded at 150 Nm, the motor speed is 800 rpm. The field constant K? of the motor is always greater than 2 Vs. The motor is controlled by a full-wave, ac/dc converter, where the voltage on the ac side is 480 V (rms). At 150 Nm, the triggering angle is adjusted so that the speed of the motor is 400 rpm. The armature current of the motor is continuous. Calculate the triggering angle and the average terminal voltage of the motor.
