Product description
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. Total weight: 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.
Core Specifications
- Motor Dimensions: Φ92.6 × 26.4 mm (Standard) | Φ88.6 × 17.7 mm (Lite)
- Weight: 352 g (Standard) | 265 g (Lite)
- Peak Torque: 4 N·m
- Continuous Torque: 1.3 N·m
- Rated Voltage: 48 V
- No-load Speed: 5040 rpm
- Feedback Sensors: Integrated Hall & Temperature Sensors (Standard) | Sensorless (Lite)
Product Highlights
- Ultra-Low Cogging Torque: Optimized electromagnetic design reduces cogging torque to ensure smooth low-speed motion, quiet operation, and fine motion control
- Large Hollow Bore Design: Central aperture facilitates cable routing, direct shaft coupling, or integration with harmonic drives
- High Torque Density: 1.3 N·m continuous and 4 N·m peak torque from a compact footprint
- Versatile Configurations: Standard version provides full feedback and rugged protection; Lite version offers an ultra-slim, frameless 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
