How to choose a BLDC motor for robotic arms and mobile robots

Selecting a BLDC motor for robotic arms or mobile robots starts with the mechanical load, not the controller catalog, according to Faisal Mahmood.

The article says engineers must check continuous and peak torque, acceleration and gravity loads, reflected inertia, and regenerative braking energy.

It also compares six-step and field-oriented control, noting that FOC is commonly chosen for smooth low-speed motion and fast torque response.
