A dc series motor has an armature resistance of 0.06 Q and series field resistance of 0.08 Q. The motor is connected to a 400 V supply. The line current is 20 A when the speed of the machine is 1100 rpm. When the line current is 50 A and the excitation is increased to 30%, the speed of the machine in rpm is 837 RPM 938 RPM 1003 RPM O 1100 RPM A d.c. series motor takes 40 A at 220 V and runs at 800 r.p.m. If the armature and field resistance are 0.2 Q and 0.1 Q respectively and the iron and friction losses are 0.5 kW, the torque developed in the armature and the output of the motor will be 80.5 N-m , 11.57 kW 96.2 N-m, 10.63 kW 99.3 N-m, 7.82 kW
