The CubeMars RO60‑KV115 Lite is a lightweight variant of the RO series, designed as a w/o Hall sensor frameless outrunner torque motor for applications prioritizing minimal weight and cost efficiency.
Operating at a rated voltage of 48 V, this version eliminates the Hall sensors and front cover to simplify construction while retaining the core advantages of ultra-low cogging torque and a large-diameter hollow shaft. With a continuous torque of 0.8 N·m, peak torque up to 2.4 N·m, and a total weight of only 195 g, it is ideal for space-constrained robotic systems where ultra-high position feedback precision is not critical—such as robotic joints, exoskeletons, collaborative arms, and medical devices.
Motor Dimensions: Φ70.5 × 15 mm
Weight: 195 g
Peak Torque: 2.4 N·m
No-Load Speed: 5520 rpm
Low Cogging Torque: Cogging torque reduced by ~50% compared to similar-class motors, ensuring smoother low-speed motion
Large Hollow Bore: Supports a generous central aperture for cable routing, direct shaft coupling, or integration with gearboxes—enhancing mechanical design flexibility
Lightweight & Simplified Design: Removal of Hall sensors and front cover reduces weight to ~195 g, making it perfect for weight-sensitive robotic platforms
High Structural Adaptability: Interchangeable shaft options and versatile mounting interfaces support diverse integration scenarios
Broad Application Scope: Optimized for exoskeletons, collaborative robot arms, medical robots, quadrupedal robots, inspection AGVs, and other compact electromechanical systems
