A 48kW, 600V, 1500 rpm separately excited dc motor is controlled by single phase semi-controlled converter. The resistance of the armature is 192 and of the field is 1450. The field circuit is controlled by a single phase fully controlled converter and its firing angle is set to 20. The AC supply voltage to the armature and field converters is a single phase 220V, 60 Hz. The voltage constant is 0.946 V/A rad/s. If the armature converter firing angle is 45 and the speed is 1200 rpm; calculate the armature current and the developed torque.
