A series motor having a resistance of 1 ohm between terminals drives a fan for which the torque varies as the square of the speed. At 220 Volt the set runs at 300 rpm and takes 25 Amp. The speed is to be raised to 400 rpm by increasing the voltage. Find the terminal voltage for the limiting cases when the field is unsaturated (i.e. flux directly proportional to current)
