Product Overview
Compact frameless power
The CubeMars RI80 V2.0 KV75 is an upgraded inner-rotor frameless torque motor from the RI series, engineered for cobot arms, exoskeletons and other high-precision robotic joints. It runs on 24, 36 or 48 V and delivers about 1.45 Nm continuous and up to 4.1 Nm peak torque with a torque density around 9.3 Nm/kg.
Optimised electromagnetics give low cogging for smooth, silky low-speed motion, while the frameless architecture lets you customise supports, flanges and bearings for a perfect fit. An optional Hall sensor enables accurate closed-loop feedback.
