CubeMars AKH70‑16 is a compact, high‑performance drive module engineered for legged robots, exoskeletons, and AGV (Automated Guided Vehicle) platforms. Powered by FOC (Field‑Oriented Control) and equipped with a dual magnetic encoder system, it delivers precise motion control, high torque output, and real‑time feedback in demanding environments.
With a robust 16:1 gear reduction, integrated CAN and UART interfaces, and support for 48V power systems, the AKH70‑16 offers exceptional scalability and responsiveness. Its low backlash design, built‑in temperature monitoring, and high inertia rotor make it ideal for dynamic load conditions and precision‑driven applications.
