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' advantages of high torque density, low cogging torque, and smooth control, this series introduces a potting process that significantly enhances coil protection and structural stability, enabling stable long-term operation 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 exoskeleton joints, collaborative robotic arms, mobile platforms, and service robots.
