Motor Control

​

Watch this series to learn about brushless DC motor control. You’ll learn about the inner workings of a BLDC, and six-step commutation (trapezoidal control). The videos will cover some examples showing how you can simulate a BLDC to investigate its back-EMF profile and design speed controllers.

Part 1: An Introduction to Brushless DC Motors

​

Learn the fundamentals of brushless DC motors (BLDCs). BLDC motors offer many advantages over brushed DC motors. They have high efficiency and low maintenance and have been commonly used in home appliances, robotics, and the automotive industry.

Part 2: BLDC Motor Control

​

Learn how the different components of a BLDC speed control algorithm work

Part 3: BLDC Speed Control Using PWM

​

This video discusses PWM—pulse-width modulation—and two different architectures to implement PWM control for controlling the speed of a BLDC motor.
