According to conventional wisdom, BLDC motors offer many advantages over conventional brush motors, but they’re thought to be much more expensive. This isn’t the case because advances in BLDC design and manufacturing make BLDC motors competitive with high-grade brush motors.
One of the problems in comparing BLDC motors to brush motors is that most comparisons tend to compare apples to oranges. Commodity brush type motors are much less expensive than BLDC motors but have very short lives. BLDC motors should be compared with high-grade DC brush motors.
This infographic examines the questions above as well as offers a more in-depth look into BLDC motor design. Learn more about the functional differences between the two motor types, potential cost savings and much more.
