Product Overview
Compact frameless power
The CubeMars RI60 KV120 is an ultra-compact inner-rotor frameless torque motor from the RI series, ideal for exoskeletons, cobots and lightweight robotic joints. It runs on 24, 36 or 48 V and delivers about 0.57 Nm continuous and up to 1.63 Nm peak torque from just 156 g.
Low cogging torque gives smooth operation, while the frameless architecture and compact form factor make it easy to embed into tight assemblies. An optional Hall sensor enables accurate closed-loop feedback.
