Question

Design a DC motor circuit to drive A fan-type load with a torque equation equal to:

TL=1.34×10−7ω2TL=1.34×10−7ω2 N.m

The fan speed range is from 500 to 1200 rpm. 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 480 V (rms) and 50 Hz.

choose the motor type, show the motor rating, αα range, Supply voltage, and frequency, and any required other information

Modify the design to automatically adjust the voltage drive the load within the specified speed range.

show the control variable, controller type, connection, and controller weights.

design the single-phase, full-wave, ac/ dc converter. show design specifications, the reason for DC motor selection. correct manual circuit, and correct automatic closed-loop control circuit
