CubeMars RO60 Lite (KV115) is a lightweight version of the standard model, designed for cost-sensitive or simple applications with a rated voltage of 48V, optimized for space-constrained scenarios. It removes the Hall sensor and front cover, simplifying the structure to reduce weight and cost, making it suitable for robotic applications that don’t require high-precision feedback or use open installation. It retains ultra-low cogging torque and a large through-hole design, supporting flexible wiring and multi-axis switching, ideal for lightweight robots, DIY projects, or prototype development. Specifications: rated torque 0.8 N.m, peak torque 2.4 N.m, rated current 8.5 A, maximum current 40 A, maximum torque-to-weight ratio 10.2 N.m/kg (due to lighter weight), rated speed 4200 rpm, weight approximately 200g.
