Product IntroductionStandard planetary joint module is a key component of power robotic systems. Thanks to its highly integrated design, combining a planetary reducer, frameless torque motor, brake, encoder, and driver, significant optimization of volume and weight is achieved, ensuring precise joint motion control. This leads to increased torque, reduced dimensions, and lower weight. Compared to harmonic joint modules, the planetary joint module has a lower reduction ratio, higher output speed, and greater torque density, making it more suitable for medium and low load applications. Customization services are also available according to specific customer requirements.With key advantages such as high performance, impact resistance, and a 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, contributing to the development of robot performance and expanding their application areas.FeaturesHigh torque density and powerMulti-stage planetary gear structure: By combining several gear stages, torque density can reach over 20N·m/kg, suitable for high-load drive requirements in hip joints, legs, and other robot parts.Peak torque: Provides higher peak torque, meeting instantaneous power requirements in dynamic motion scenarios.Impact resistance and high reliabilityAdvantages of planetary transmission: Gear meshing distributes impact force, can withstand harsh working conditions such as emergency stops and frequent load changes, suitable for highly dynamic scenarios like walking and jumping of bipedal robots.Mass production controllability: The planetary reducer solution uses mature technology with high consistency and reliability in mass production, suitable for large-scale applications.Compact and lightweight designHigh integration: Nested design of planetary reducer, frameless motor, encoder, and other components reduces volume by 30% compared to traditional solutions.Lightweight materials: Use of high-strength alloys and compact layout meets the strict requirements of humanoid robots for lightness and high energy efficiency.High precision and low energy consumptionLow cogging torque and dual closed-loop encoder: Reduces torque ripple, combined with dual absolute encoders (motor and output side) achieves positioning repeatability of ±0.05°.Transmission efficiency optimization: Planetary reducer efficiency exceeds 80%.Coordinated multi-axis controlSupports CAN bus protocol to meet the requirements of coordinated movement of robots with multiple degrees of freedom.Cost-effectiveness and ease of maintenanceMaintenance-free design: Stable planetary reducer structure does not require regular lubrication, reducing long-term operating costs.Modular interfaces: Standardized design facilitates quick replacement and upgrades, shortening robot development cycles.AdvantagesPower unitFrameless torque motor: Provides a compact power source, suitable for high dynamic response requirements.Two-stage planetary reducer: Optimizes space with a nested gear structure, increases torque transmission efficiency.Sensors and controlDual absolute encoders (motor and output side): Support full closed-loop control, improve positioning accuracy.Friction brake: Ensures safety during emergency stops and stable zero-speed start.Communication moduleSupports CAN bus protocol, compatible with coordinated multi-axis control.SpecificationsPlanetary Joint Module ParametersSizeSpeed RatioReduction RatioRated TorquePeak TorqueRated SpeedPeak SpeedResolution (motor/reducer)Communication InterfaceEncoder RepeatabilityPower Supply VoltageWeightHollow Shaft DiameterUnitmm/VN·mN·mRPMRPMbit/ArcsecV(DC)kgmmJRM4054006481335035017-bit (131072)CAN4048V≈0.25/406603648618505017-bit (131072)CAN4048V≈0.35/50700204861917017017-bit (131072)CAN4048V≈0.43/607002048124015015017-bit (131072)CAN4048V≈0.6ø5706922.548206017017017-bit (131072)CAN4048V≈0.8/807802448309510010017-bit (131072)CAN4048V≈1.1ø59579.600848186040040017-bit (131072)CAN4048V≈1.6ø59579.9024485020012012017-bit (131072)CAN4048V≈1.6ø510483.520.4485030015015017-bit (131072)CAN4048V≈1.9ø812588020488036015015017-bit (131072)CAN4048V≈2.8/12588024489045012012017-bit (131072)CAN4048V≈2.8ø8Peak torque is calculated for instantaneous use within 5 seconds.
