Product Overview
Compact frameless power
The CubeMars RI50 KV100 is the most compact inner-rotor frameless torque motor in the RI series, built for space-critical cobot and exoskeleton joints. It runs on 24, 36 or 48 V and delivers about 0.58 Nm continuous and up to 1.67 Nm peak torque from a 181 g body.
Low cogging torque gives smooth, precise motion, while the extremely compact frameless design saves valuable space in tight assemblies. An optional Hall sensor supports accurate closed-loop control.
