## Summary

This article systematically explains how to choose brushless DC (BLDC) motors for robotic arms and mobile robots, emphasizing that selection should start from the mechanical load rather than the controller catalog, and covering torque calculation, commutation methods (six-step, sine, FOC), feedback architecture, communication interfaces, and safety design. The article provides a ten-step selection process, a decision table for control schemes in different application scenarios, as well as debugging verification and an engineer checklist.
