Optimizing BLDC Motor Control Through System Simulation

Siddharth Mohan, Sr. Design Engineer, Qorvo

Why BLDC motors? Electric motors are responsible for roughly 50% of the world’s total electrical energy consumption, according to the European Commission1. Improving motor efficiency not only reduces operational costs but also plays a vital role in lowering global CO₂ emissions. Among available motor te
