A belt-driven 0.16 MW shunt-wound DC generator is running at 460 rpm and is supplying full load to a bus bar at 230 V. At what speed will it run if the belt breaks and the machine continues to run taking 9 kW from the bus bar? The armature and the field resistances are 0.05 Ohm and 100 Ohms respectively. The brush contact drop is 2 Volts per brush.
