The Second Pic Is The Diagram For The Question
Single-phase full wave converters as shown in Figure 2 control the armature and the field circuits of a separately excited DC motor. The field converter has a delay angle of 45° and the armature converter delay is 250. The AC supply to both the armature and field circuits is 230 V at 60Hz. The armature resistance Rs = 1.5 and the field resistance R is 3000. The motor voltage constant is Ky =0.71 V/A rad/s. The torque developed by the motor is 20 Nm. Assume that the viscous friction and no-load losses are negligible and the inductances of both the armature and field circuits are such that the currents are continuous and ripple free. Determine a. The armature current of the motor b. The motor back EMF C. The motor speed d. The input power factor of the drive.
