In petrochemical facilities, an explosion-proof inspection robot extends its mechanical arm to accurately position an infrared thermal imager on a high-temperature pipeline flange, demonstrating smooth movements and precise positioning. In coal mines, another robot's arm performs micron-level rotational operations on valves. The motors driving these joints differ fundamentally from standard industrial robots, providing high torque density in confined spaces.
These explosion-proof joint modules can achieve a peak torque of 450 N·m and a rated torque of 110 N·m, supporting continuous operations with a payload exceeding 20 kg. With a dual 17-bit encoder, the modules offer a repeat positioning accuracy of ±40 arc seconds and a backlash of ≤15 arc minutes, with response times in the millisecond range. Designed for flammable and explosive environments, these robots meet IP68 protection and Ex d IIB T4 explosion-proof standards, suitable for various scenarios including chemical, coal mining, and hazardous material warehouses.
Jiangsu Huistone has over 20 years of experience in specialized motors, providing customized servo motor solutions for intelligent inspection robot arms. Their products cover a base size range from 40 mm to 400 mm, power from 50 W to 200 kW, and voltage from 24 V to 3000 V, ensuring compatibility with different power supply platforms. The successful application of their 130 mm base explosion-proof AC servo motor in petrochemical inspection robots highlights the precision and safety of these advanced technologies.
