3. A 25 Kw shunt generator is delivering full output to 400V bus bars and is driven at 950 rpm by belt drive. The belt breaks suddenly but the machine continues to run as a motor taking 25 Kw from the bus bars. At what speed does it run? Take armature resistance including brush contact resistance as 0.5 ohm and field resistance as 160 ohms.
