A belt driven dc shunt generator runs at 1500 rpm delivering 10kW, at 220V bus bars. The belt breaks, following which the machine operates as a motor drawing 2kW power. What will be its speed as a motor? The armature and field resistances are 0.25 ohms and 55 ohms respectively. Ignore armature reaction and assume the contact drop at each brush to be 1V.
