CubeMars RI50 KV100 Frameless Motor Low Cogging Torque
Compact for Robotic Joints Exoskeletons
The RI50 KV100 is a frameless inrunner torque
motor from CubeMars’ RI series, engineered for
applications where space is limited but rapid
response and high dynamics are essential—such as
robotic joints, exoskeletons, collaborative robot
arms, and AGV hub drives. Featuring high torque density,
ultra-low cogging torque, and an exceptionally small
form factor, it delivers outstanding dynamic performance
and exceptional mechanical integration flexibility.
