A belt-driven, 150 kW shunt wound dc generator is running at 450 rpm, full load to a bus bar at 240 V. At what speed will it run if the belt breaks and the machine continue to run as a motor taking 8.5 kW from the bus bar? The armature and field resistances are 0.1 and 80 ohms, respectively. Total brush contact drop is 2 V. Neglect armature reaction.
