It’s true that BLDC motors offer many advantages over conventional brush motors, but many think they’re much more expensive. This is technically not the case. Thanks to advances in BLDC design and manufacturing, brushless motors are cost 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 will examine these facts and more!
