RI50 KV100

Product Description

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.
