CubeMars RO60 KV115 Motor
CubeMars RO60 KV115 Motor
Product Description
The CubeMars RO60 KV115 is a newly launched frameless outrunner torque motor in the RO series, equipped with built-in Hall sensors as standard. It is specifically engineered for high-performance applications such as robotic joints, exoskeletons, collaborative robot arms(cobot), medical devices, and aerospace systems.
Operating at a rated voltage of 48 V, this motor features an ultra-low cogging torque design and a large-diameter hollow shaft, enabling flexible shaft replacement and versatile mounting configurations (e.g., direct integration with gearboxes, wiring through the center, or drive shaft pass-through). Integrated Hall and temperature sensors provide precise rotor position feedback and real-time thermal monitoring for enhanced control accuracy and system safety.
With a continuous torque of 0.8 N·m (peak torque up to 2.4 N·m) and a total weight of only 248 g, the RO60‑KV115 delivers exceptional responsiveness and stability in space-constrained robotic platforms.

Product Description
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.
