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.

• Highly Integrated, Compact and Lightweight Design: Integration of harmonic drive and frameless torque motor results in compact structure; suitable for space-constrained scenarios (robot wrists, head joints). Uses high-strength aluminum alloy, carbon fiber and other materials to reduce weight and improve 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; designed precision lifespan exceeding 10,000 hours; impact resistance and ability to withstand high-load emergency stops.
• Intelligent Integration and Control: Embedded controller with multi-protocol compatibility (EtherCAT, CANopen), dynamic PID adjustment; modular design with standardized interfaces for quick integration and maintenance.
