The CubeMars RO series brushless DC outer rotor torque motor is introduced to meet diverse market demands, catering to applications in exoskeleton robotics, collaborative robotic arms, as well as medical and aviation fields. After a year of market research and meticulous engineering, the RO series has been launched in December 2023.As the new favorite across the entire series, based on the foundation of the R series, the RO series has undergone careful upgrades to address challenges in robot joint design. It successfully tackles issues related to limited internal installation space within joints and increased torque requirements.
Product Features:
1. Ultra-Low Cogging Torque: The RO series motor exhibits 50% lower tooth count torque compared to the R series, ensuring smoother operation at low speeds.
2. Large Hollow Through-Hole: In comparison to the GL series, the RO series motor boasts a larger hollow diameter, adapting flexibly to various diameter requirements, allowing for versatile applications with a simple shaft replacement.
3. Integrated Temperature and Hall Sensors: Real-time monitoring of motor temperature prevents damage due to abnormal temperatures, and precise positioning control is provided through Hall sensors.
4. Aluminum Alloy Housing: The rotor of the RO series adopts an aluminum alloy housing, enhancing impact resistance, corrosion resistance, and providing various customization possibilities for appearance. This also improves transparency in controlling raw material costs.
5. Easy Installation: Stator features pin holes for easy assembly, and the product is equipped with magnetic pins and screws, greatly simplifying the installation process.
