CubeMars RI75-PH KV70 Motor

Product Description

The CubeMars RI75‑PH KV70 is a potting frameless inrunner torque motor engineered for high-reliability applications. Building on the RI series’ inherent advantages of high torque density, low cogging torque, and smooth control, this series introduces a potting process that significantly enhances coil protection and overall structural stability.This enables the motor to maintain long-term, stable operation even in harsh environments characterized by high temperatures, vibration, moisture, or dust.

Thanks to its lightweight stator-rotor design and excellent thermal conductivity, the RI75‑PH KV70 delivers powerful output within an ultra-compact size. It is ideally suited for demanding applications such as exoskeleton joints, collaborative robotic arms, mobile platforms, and service robots—where space efficiency, dynamic responsiveness, and durability are critical.
