11. DC Motor Speed Control: PWM Explained Simply

https://www.kimiagh.com/ Unfortunately, I forgot to share my computer screen while teaching this lecture; however, all concepts, explanations, and calculations are fully covered verbally and conceptually throughout the session. Pulse Width Modulation (PWM) is one of the most important concepts in DC motor control and embedded systems. In this lecture, I explain how PWM works, how duty cycle affects DC motor speed, and how to implement PWM for motor control using microcontrollers. In addition to PWM fundamentals, this lecture covers first-order low-pass filter (RC) design for smoothing PWM signals into an analog-equivalent voltage. You will learn how to calculate the appropriate resistance and capacitance values, select cutoff frequency relative to PWM frequency, and understand the trade-offs between ripple, response time, and system stability. The lecture combines theory and practical design considerations, including PWM frequency, resolution, filtering, and real-world implementation in robotics, automation, and mechatronics systems. This video is ideal for engineering students, embedded systems learners, and anyone working with DC motor control and signal conditioning. #pwm #dcmotor #motorcontrol #firstorderfilter #lowpassfilter #rcfilter #embeddedsystems #microcontroller #robotics #mechatronics #controlsystems #electronics #engineering #arduino #motorprogramming #automation #electricalengineering #stemeducation #engineeringlecture #pwmcontrol #dcmotorcontrol #embeddedprogramming #hardwareprogramming
