Spinning a BLDC motor may be as simple as activating electromagnet pole pairs. If you turn on and sequence these pole pairs correctly, the rotor will rotate 360 degrees. One of the most important things to consider is the timing of this activation. That’s where sensors come in.
For a quick lesson on the basics of sensored BLDC operation, check out the newest Engineer It video from motor driver marketing manager Mike Firth. In the video below, he discusses the basic operation of motors within a sensored architecture.
