The Trade-offs in Motor Drives: Open-Loop vs. Closed-Loop Hall Sensors - A Deep Dive into Cost, Accuracy, and Bandwidth.
the selection between open-loop and closed-loop Hall current sensors is a fundamental engineering decision centered on balancing performance needs with economic reality. Open-loop sensors offer a compelling solution of simplicity and low cost for mainstream applications. In contrast, closed-loop sensors deliver unparalleled accuracy and speed for demanding, high-performance motor drives, justifying their higher cost. Understanding these trade-offs empowers designers to optimize their systems for both performance and value.
