QUESTION 27 A shunt-wound DC motor operates from a 440VDC power supply and runs at Orade when ite armature current is 10A. The effective resistance of the armature circuits 19. The speed of the motor is controlled by using a series resistance in the armature current for speeds below 50rades, and by using the field resistance for speeds above 50rad s (see the Diagram below) la la Rx RV 11 M DC Supply Vs DC Supply Vs M Shunt Field Shunt Motor Shunt Motor Calculate the speed of the motor m rad see when Ta-5A and the series armature control resistance is O and the field resistance is set to reduce the fux by 25% Give your answer with 3 tagnificant digits
