Introduction of planetary joint motor
The Standard Planetary Joint Motor is a core component of robotic power systems. Through highly integrated design combining a planetary reducer, frameless torque motor, brake, encoder, and driver, it achieves significant optimization in volume and weight, enabling precise motion control of the joint. This results in greater torque, smaller size, and lighter weight. Compared to harmonic joint modules, the planetary joint module features a smaller reduction ratio, higher output speed, and greater torque density, making it more suitable for medium-to-low load applications. We also provide customization services tailored to clients’ specific requirements.
With core advantages such as high-speed performance, impact resistance, and compact lightweight design, the Standard Planetary Joint Module has become the preferred solution for high-load drives in humanoid robots, specialized robots, logistics AGVs, and industrial automation, driving advancements in robotic performance and broader application scenarios.
