CAN-FD
The Leadshine PJ3 series joint modules feature a durable harness (7M torsion cycles), versatile mounting, and fits various humanoid decoupling configurations; its self-developed frameless motor delivers >80% efficiency with <60K temperature rise, and plug-and-play EtherCAT/CANFD support greatly reduces tuning time.

Hollow Design
The hollow planetary module design simplifies robot cabling and makes EtherCAT/CAN wiring more convenient.

Ultimate Reliability and Durability
An innovative clamp-style connection eliminates intermediate components, enhancing structural rigidity and torque transmission efficiency.

Ultra-compact Design
The lightweight mechanical structure features hollowed-out sections to reduce weight by 15%.
Leadshine PJ3 series planar integrated actuators are mainly used for multi-degree-of-freedom components of humanoid robots or quadruped dogs, such as lower limb joints, waist and hip joints, supporting complex movements including walking, grasping, operation and interaction.
• High power density to meet the demands of high-speed and high-load actions
• Lightweight and compact structure to reduce overall robot weight
• High-precision position and torque control for natural and smooth movement
• Integrated frameless motor, ring-shaped driver, and hollow encoder for easy modular installation
• Built-in overload protection and safety control algorithms to enhance human-robot interaction safety
Leadshine's joint module products, featuring ultra-high torque density, ultra-low temperature rise, and an extremely compact design, are widely applicable to industry solutions for humanoid robots, quadruped robots, collaborative robots, and more.
The module is designed for flange mounting. The hollow structure facilitates routing of air pipes, cables, etc. through the center. Installation at any angle is supported. It is recommended to install according to the 3D drawing while keeping the axial load centered.
Yes. We can provide standard installation interface dimensions, flange interfaces, output shaft dimensions, and other information. Fast non-standard customization services are also available.
They support mainstream protocols such as EtherCAT、CAN and CAN FD, offering good compatibility. Communication manuals and sample code are available for quick integration with mainstream controllers.
Yes. Debugging tools and basic development interfaces (e.g., communication protocol documents) are provided to facilitate quick access and testing for developers.
Both harmonic gear and planetary reducer options are available. Harmonic reducers are lightweight and high-precision, making them suitable for collaborative robots. planetary reducers offer high rigidity and impact resistance, making them suitable for industrial robots or heavy-load applications. Under normal operating conditions, the lifespan is generally 5 to 10 years.
The design lifespan is typically over 10,000 hours, supporting 7×24 continuous operation.
They have been applied in collaborative robots, industrial automation, humanoid robots, and medical rehabilitation robots, with positive customer feedback and stability exceeding that of competitors.
Standard modules are recommended for use in normal room temperature environments.
Yes. The modules have built-in temperature, current, and voltage detection mechanisms, and feature multiple protection functions including over-temperature, over-current, and stall protection.
Yes. Non-standard customization is supported, including flange dimensions, shaft length, output type, communication interface, cable interface, and more. You are welcome to provide 3D drawings or technical requirements to discuss customization details.
Due to the integrated design, some components may not be suitable for individual replacement. However, detailed maintenance instruction videos or illustrated manuals can be provided to assist customers with maintenance operations.
