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.
Part 4: Understanding Field-Oriented Control Field-oriented control (FOC) is a technique used to control various motor types, including permanent magnet synchronous machines (PMSMs). Watch this video to learn how the FOC algorithm works.
Part 5: Space Vector Modulation Space vector modulation (SVM), also known as space vector pulse width modulation (SVPWM), is a common technique in field-oriented control for permanent magnet synchronous motors (PMSM).
Part 6: 10 Practical Considerations for Implementing FOC with Simulink This video walks you through the various tasks required for designing and implementing field-oriented control, ranging from algorithm design to modeling and control tuning to deployment.
