A belt-driven 100-kW, shunt generator running at 300 RPM on 220-V busbars continues to run as a motor when the belt breaks, then taking 10 kW. What will be its speed when the armature resistance = 0.025 ohms, field resistance = 60 ohms and contact drop under each brush = 1 V? Assume the flux deteriorates by 25% when ran as a motor.
