A dc generator is connected to a 220V dc mains. The current delivered by the generator to the mains is 100A. The armature resistance is 0.1Ω the generator is driven at a speed of 400rpm. Calculate a) the induced emf, b) the electromagnetic torque, c) the mechanical power input to the armature neglecting iron, windage and friction losses, d) the power input and output of the armature when the speed drops to 350 rpm. State whether the machine is generating or motoring. Assume constant flux?
