CubeMars RO100 KV55 Motor

Product Description

The CubeMars RO100‑KV55 Standard is a high-performance frameless outrunner torque motor engineered for demanding applications such as robotic joints, exoskeletons, collaborative robot arms, medical devices, and aerospace systems.

Operating at a rated voltage of 48 V, it features an ultra-low cogging torque design and a large-diameter hollow shaft—enabling flexible integration options including through-hole wiring, direct shaft coupling, or direct connection to harmonic drives. Equipped as standard with Hall sensors and a temperature sensor, the motor delivers precise rotor position feedback and real-time thermal monitoring for enhanced control accuracy and system safety.

With a continuous torque of ~4 N·m and a peak torque of up to ~12 N·m, the RO100‑KV55 delivers robust power in a compact, lightweight package (710 g), making it ideal for high-dynamics robotic platforms requiring smooth motion and high reliability.
