CubeMars RI85-PH KV85 Motor

Product Description

The CubeMars RI85‑PH KV85 potting frameless inrunner torque motor features a potted, frameless inner-rotor design engineered for demanding applications such as robotic joints, exoskeletons, collaborative arms, and lightweight mobile platforms—where structural integration, dynamic response, and long-term reliability are critical.

By encapsulating windings and internal components with potting compound, this motor significantly enhances resistance to vibration, thermal stress, and environmental exposure, greatly improving operational lifespan and stability. Combined with an optimized electromagnetic design, it achieves approximately 25% higher torque and power density compared to conventional counterparts.
