Motor Control, 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.

You’ll learn:

- The inner workings of BLDCs
- How you can simulate a BLDC in Simulink® using Simscape Electrical™ and investigate the shape of its back-EMF voltage
- How a BLDC is controlled using six-step commutation (trapezoidal control)
- How BLDCs and permanent magnet synchronous machines (PMSMs) are commonly controlled by trapezoidal and field-oriented control, respectively
- Check out this video to learn how you can build a model of a BLDC from scratch and simulate its back-EMF voltage using Simscape Electrical.
