Introduction
The Robot Joint Motor achieves highly precise motion control through integrated components including harmonic drive, frameless torque motor, brake, encoder, and drive unit, with optimized size and weight. It delivers greater torque, higher precision, more compact size and lighter weight. We also provide customization services according to customers' specific requirements. Robot Joint Motors typically support a wide voltage range of DC24V~DC48V. As a core component in robotics industry, the technological advancement of Robot Joint Motors will continue to promote the development of specialized robots and humanoid robots towards higher flexibility and broader application scenarios. Beyond robotics, Robot Joint Motors are also applied in semiconductor equipment, photovoltaic equipment, precision medical equipment, 3C equipment, optical equipment and other fields.

Core Components

• Power Unit (Frameless Torque Motor): Provides high torque density and compact structure, suitable for high dynamic load scenarios.
• Harmonic Drive: Achieves speed reduction and torque multiplication, featuring zero backlash and high precision (backlash controlled within 20 arcsec).
• Dual Encoders (Motor-side + Output-side): Support full closed-loop control with repeat positioning accuracy of ±10 arcsec.
• Temperature Sensor: Monitors load and environmental status in real time to enhance safety and adaptability.
• Embedded Drive Unit: Supports protocols like EtherCAT and CANopen, enabling dynamic PID adjustment.

Features

• Superior precision & zero backlash: Zero-backlash design eliminates transmission clearance of traditional reducers, achieving repeat positioning accuracy of ±10 arcsec and absolute positioning accuracy of ±30 arcsec, suitable for precision motion control scenarios (e.g., surgical robots, collaborative robotic arms).
• 3D Conjugate Dual-Arc Tooth Profile Technology: Optimizes tooth profile structure, reduces vibration and noise, improves transmission stiffness and service life for smoother and more precise robot movements.
• Highly Integrated, Compact and Lightweight Design: High integration of harmonic drive and frameless torque motor results in compact structure suitable for space-constrained scenarios (e.g., robot wrists, head joints). Uses high-strength aluminum alloy, carbon fiber and other materials to reduce weight and improve robot energy efficiency and flexibility.
• High Transmission Efficiency: Transmission efficiency exceeds 80%, reducing energy loss and supporting efficient power transmission under dynamic load changes.
• High Safety and Reliability: Torque sensor integration (customizable) supports collision detection and drag teaching functions. Impact resistance and long service life: harmonic drive can withstand high-load emergency stops, designed precision lifespan exceeding 10,000 hours.
• Intelligent Integration and Control: Embedded controller with multi-protocol compatibility (EtherCAT, CANopen) and modular design with standardized interfaces for quick integration and maintenance.
