A 600V, 150hp, DC series motor operates at it's full-ratedload at 600 RPM. The armature resistance is 0.12 ohms and theseries field resistance is 0.04 ohms. The motor draws 200A at full load.
A) Determine the armature voltage Ea atfull-load.
B) Determine the armature-developed power Pdev and intenal-developed (induced) torque in Nm.
C) Assume that a change in load results in the line currentdropping to 150A; determine the new speed in RPM and the newdeveloped torque Tdev .
