CubeMars AKE80-8 Actuator Motor delivers cutting-edge performance for industrial automation and robotics. Integrating a high-performance motor and a precision planetary gearbox, the AKE80-8 is expertly engineered for demanding applications such as exoskeletons, bipedal robots, robotic arms, and collaborative industrial robots.
With optimized core gearbox components, this actuator achieves a peak torque of 30 Nm, ultra-low backlash of 9 arcminutes, and an exceptional torque density of 52 N·m/kg—all while maintaining a compact, lightweight design (570 g). The modular construction allows for quick installation and straightforward maintenance, and the motor base is equipped with threaded and through holes for flexible, bi-directional mounting, seamlessly meeting diverse integration needs.
Engineered with grade 5 precision gears and an enhanced winding process, the AKE80-8 features quiet, efficient operation, increased slot fill factor (boosted by 10% over previous generations), and superior torque output with reduced thermal rise. These innovations guarantee consistent, precise, and reliable performance.
