How to Control Brushless Motors (Part 2): Position Control Loops (Download)
Brushless DC (BLDC) motors are being widely adopted in high-performance motion control. Unlike brushed motors, they don't rely on mechanical brushes that tend to wear out over time. Instead, they use electronic commutation to control torque and speed, resulting in higher efficiency, greater power density, and longer lifespan.
These advantages come with tighter control requirements. Such motors depend on real-time, low-latency control loops to achieve stable, quick-response movement.
