CubeMars RO80 Motor

Product Description The CubeMars RO80-KV105 series features high-performance, frameless outrunner torque motors engineered as precision drive solutions for robotic joints, exoskeletons, and space-constrained electromechanical systems. Operating at a rated voltage of 48 V, these motors deliver a continuous torque of 1.3 N·m, a peak torque of up to 4 N·m, and a no-load speed of 5040 rpm.

This series offers two functional configurations tailored to different system complexities:

• RO80-KV105 Standard: Features an aluminum alloy housing, integrated Hall sensors for precise rotor position feedback, and a temperature sensor for real-time thermal monitoring, offering enhanced system safety and control accuracy at a total weight of 352 g.

• RO80-KV105 Lite (w/o Hall): A streamlined, cost-effective variant that removes the Hall sensors and housing to achieve an ultra-lightweight profile of just 265 g, ideal for highly weight-sensitive applications.

Product Highlights

• Ultra-Low Cogging Torque: Optimized electromagnetic design reduces cogging torque to ensure exceptionally smooth low-speed motion, quiet operation, and finer motion control.

• Large Hollow Bore Design: Generous central aperture facilitates easy cable routing, direct shaft coupling, or seamless integration with harmonic drives, maximizing design flexibility.

• High Torque Density: Delivers an impressive 1.3 N·m continuous and 4 N·m peak torque from a compact footprint, providing high-response actuation for demanding motion profiles.

• Versatile Configurations: Standard version provides full feedback and rugged protection, while the Lite version offers a ultra-slim, frameless, and cost-effective layout for maximum weight savings.

• Broad Application Compatibility: Tailored for exoskeleton robots, collaborative robot arms, medical devices, aerospace robotics, quadrupedal platforms, and lightweight AGV wheel-drive systems.
