Extracted text: X.PROBLEM: (Show your solution) 1. A 550-volt long shunt compound motor has an armature resistance of 0.815 ohm and a series field resistance of 0.15-ohm. The full load speed is 1900 rpm when the armature current is 22-Amp. a) At what speed will the motor operate at no load if the armature current drops to 3-amp with corresponding drop in flux to 88 % of the full load value. Assume a brush drop of 5-volts at full load and 2-volt at no load b) Calculate the percent speed regulation of the motor. V OR SERVATION.
