QUESTION 27 A shont-wound DC motor operates from a 440VDC power supply and runs at Sorad's when its armature current is 10A The effective resistance of the armatore circuits 10. The speed of the motor is controlled by using a series resistance in the armature current for speeds below 50rads, and by using the field resistance for speeds above 5Orad s (see the Diagram below) la la Rx Rv 11 DC Supply Vs DC Supply Vs Shunt Motor Shunt Motor Calculate the speed of the motor in rad sec When =5A and the series armature control resistance is O and the field resistance is set to reduce the flux by 25% Give your answer with 3 significant digits.
