) A shunt motor draws a current of 40 A from a 120 V source and runs at 1200 rpm at rated load. The armature and field circuit resistances are 0.1 ohm and 60 ohms, respectively. Determine the speed regulation of the motor at half load. Assume a brush drop of 2 V at rated load and 1 V at half load. Ans.: 2.5%
