Tutorial explains BLDC motor selection methods for robotic arms and mobile robots

Faisal Mahmood, author at The Robot Report, published a tutorial systematically explaining how to select BLDC motors for robotic arms and mobile robots, arguing that selection should start from the mechanical load rather than looking at controller catalogs first. The content covers torque calculation, commutation methods (six-step, sine, FOC), feedback architecture, communication interfaces, and safety design, and provides a ten-step selection process, a scenario-based control scheme decision table, and a commissioning and verification checklist. The article notes that estimation formulas such as torque cannot replace dynamic models and can only expose key parameters before selecting a controller; no-load bench tests can verify only part of the system; safety functions need to be designed, verified, and integrated according to applicable requirements.
