The parameters of a separately excited DC motor are given as. Ra = 5 Q Kt = 5 V/rpm.Wb, 0 = 160 mWb. The rectifier is fed with an a.c. source of 230 V at 50 Hz. The firing angle a is set at 45°, and the average speed is 1200 rpm. Find a) back emf generated in the motor Assuming continuous current, calculate the armature current if the rectifier is: (0) Fully- controlled bridge a) armature current ( b) torque developed (* Assuming continuous current, calculate the armature current if the rectifier is: (1 Semi- controlled bridge a) armature current b) torque developed *
