🔬 Explore every detail

The SP planetary robot joint is the result of careful development that emphasizes integration and performance. Its robust metal planetary gearing can handle high torque and offers accuracy better than ±12 arcmin (0.2 degrees). Low noise (<70 dB) and high speed ensure smooth and efficient operation. The double-bearing output shaft eliminates axial play, which is key to stable and repeatable movements.

The heart of the module is a brushless torque motor with external rotor, designed for an ultra-long lifespan of over 5000 hours. The integrated drive, designed with FPGA technology, ensures stable performance and strong immunity to interference, while the CAN2.0A bus interface with a speed of 1.0MHz enables fast and reliable communication. With freely accessible parameters for current, speed and position rings, you have full control over all working modes.
