Manual Control: Design a dc motor circuit to drive an assembly line consisting of a conveyor belt moving horizontally. The load on the belt varies depending on the number of goods being moved. The load torque seen by the motor varies from a maximum of 20 Nm to a minimum of 5 Nm. At all loading conditions, the speed of the motor must be maintained constant and equal to 150 rpm. a. To achieve the required operation, the armature voltage of the motor is adjusted by a single-phase, full-wave, ac/dc converter. The input voltage and frequency to the converter are 240 V (rms) and 50 Hz. (Hint: Motor type, Motor rating, α range, Supply voltage, and frequency...etc) Automatic Control: Modify the design to automatically adjust the voltage to maintain the speed equal to 200 rpm within the specified torque range. (Hint: control variable, controller type, connection, controller weights..etc)

1-The power output of the three phase machine is greater than the single phase machine. (TRUE/FALSE) 2-In thermocouple, when both the junctions are at the same temperature, the potential difference developed across both junction is zero. (TRUE/FALSE) 3-Due to decreased armature m.m.f., the armature reaction during load condition will increase and hence field flux will be distorted. (TRUE/FALSE) 4-While applying voltage in CRO, the grid is positive with respect to cathode. (TRUE/FALSE) 5-Losses in transformers are generally low and thus efficiency is high. (TRUE/FALSE)
