CubeMars RI50 KV100 Motor
Product description
Product Description
The RI50 KV100 is a frameless inrunner torque motor from CubeMars' RI series, engineered for applications where space is limited but rapid response and high dynamics are essential—such as robotic joints, exoskeletons, collaborative robot arms, and AGV hub drives. Featuring high torque density, ultra-low cogging torque, and an exceptionally small form factor, it delivers outstanding dynamic performance and exceptional mechanical integration flexibility.
Core Specifications
- Motor Dimensions: Φ54 × 27 mm
- Hollow Shaft Diameter: 22 mm
- Weight: 180.8 g
- Peak Torque: 1.67 N·m
- No-load Speed: 4008 rpm @ 48V
Product Highlights
- High Torque Density: Continuous torque of ~0.58 N·m and peak torque of ~1.67 N·m for lightweight robotic joints and modular actuators
- Low Cogging Design: Optimized electromagnetic structure minimizes cogging torque for smoother motion and higher control precision
- Frameless Architecture: Supplied as separate rotor and stator components, allowing users to customize mounting structures and integrate with gears, flanges, or bearings
- Compact & Lightweight: Only 180.8 g with Φ54 mm outer diameter and 27 mm length, ideal for highly constrained spatial layouts
