AKH70‑48 is a next‑generation drive module engineered for dynamic robotics, wearable exoskeletons, and automated guided vehicles (AGVs). Featuring FOC (Field‑Oriented Control) and a powerful 48:1 gear reduction, it delivers up to 222 Nm rated torque and 159 Nm peak output, making it ideal for high‑load, precision‑driven applications.
Equipped with dual 21‑bit magnetic encoders, CAN/UART communication, and NTC thermal monitoring, the AKH70‑48 ensures real‑time feedback, stable control, and seamless system integration. Its ultra‑low backlash (2.22 arcmin) and high rotor inertia provide exceptional stability under dynamic conditions, while the compact form factor supports embedded deployment.
