Motion control plays a vital role in industrial atomization. Application wise variety type of motors like DC, AC, stepper or servo are used. Because of easier control DC motors are very popular to the users, its application is oriented very useful for rotation and speed. As speed depends on voltage applied to the terminal, smoothly can be controlled down to zero and again accelerated opposite way without using power CKT and switching CKT. Hence, if voltage across motor terminal is varied, then speed can also be varied. One of the best controlling method for DC motor is armature voltage control method using PWM. Speed of the motors depends on the variation of the duty cycles. Direction control can be achieved by the same microcontroller using slight modifications in its programming language. Depending on the application speed range vary in DC motor. Analysis and design of any system in real time can be easily implemented by hardware technology also by smart software. A motor driver IC is interfaced to the microcontroller for receiving PWM signals and delivering desired output for speed control of a small DC motor. The combination provides smooth speed control in both clockwise as well as anticlockwise direction.
