Entering the future of drive technology with new dimensions and features for robotics: The new BXI is the most powerful integrated drive system in the Faulhaber portfolio to date and was developed to meet the new demands of modern robotics applications.

Human-like movements place the highest demands on precision, power, and dynamics—from delicate gripping motions to powerful, coordinated joint movements. This is exactly where the Faulhaber BXI comes in. The 9317 BXI G series internal rotor motor combines robustness with exceptional compactness and sets new standards for integrated drive systems in robotics. With a maximum torque of up to 20 Nm, it enables dynamic movements, fast response times, and highly precise motion control. The motor supports a voltage range up to 50 V and, thanks to its available interfaces and a length of just 1.3 inches, can be easily integrated into existing system architectures. This makes the BXI particularly suitable for applications where every inch, every pound, and—above all—high power density are critical, such as a compact joint drive in humanoid robots. The drive system forms a functional unit consisting of a motor, an integrated stepped planetary gearbox, and a high-resolution encoder. Its particular strength lies in its seamless integration: maximum performance with minimal space requirements. The flat aluminum housing offers corrosion resistance while also supporting optimized heat dissipation. The internal rotor design, featuring 21 pole pairs, a slotted stator, and an iron-core winding, ensures low cogging torque and high torque density.
