Product Overview

Compact frameless power

The CubeMars RI70 KV95 is an inner-rotor frameless torque motor from the RI series, built for cobot arms, exoskeletons and precision robotic joints. It runs on 24, 36 or 48 V and delivers about 0.94 Nm continuous and up to 2.68 Nm peak torque from a 270 g body.

Low cogging torque gives smooth, silky low-speed motion, while the frameless architecture allows seamless integration into your own mechanical design. An optional Hall sensor supports accurate closed-loop control.
