To compete in a market increasingly driven by efficiency concerns, vendors of industrial machines and household appliances must make best use of high-efficiency brushless DC (BLDC) motors. Today’s microcontrollers offer the compute power and specialized features needed to leverage BLDC motors while minimizing implementation costs. The most useful microcontroller features are specialized timers and on-chip CPU accelerators that eliminate the need for an external digital signal processor (DSP)—even in sensorless control applications. Taking advantage of these features with BLDC motors helps meet government regulations for power efficiency and qualify for ratings (such as Energy Star) that boost sales.
