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 is designed to combine robustness with exceptional compactness and set 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 high-precision motion control.

The motor supports a voltage range up to 50 V and, thanks to its available interfaces and a length of just 34 mm, can be easily integrated into existing system architectures. This makes the BXI particularly well-suited for applications where every millimeter, every gram, 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. The integrated absolute encoder with 15-bit SSI, line driver, and compensation algorithm handles precise positioning, is insensitive to interference, and is designed to significantly contribute to the reliability and accuracy of the entire system.

When combined with the FAULHABER MC5010 motion controller, the result is a perfectly matched complete system for torque-sensitive and high-precision positioning tasks. At the same time, the motor and drive are reliably protected, while commissioning is particularly simple and efficient thanks to the Motion Manager software. Thus, the FAULHABER BXI offers a powerful, future-oriented solution for demanding robotics applications where innovation, application, and new technology can work together seamlessly.
