About AK80-9 V3.0 KV100

AK80-9 V3.0 KV100 combines a 100 Kv brushless outrunner, 9:1 planetary transmission, field-oriented controller and single 16-bit magnetic encoder in a 98 mm-diameter, 490 g module. CubeMars specifies servo and MIT hybrid control modes and a combined CAN/power interface with UART access.

The current model is rated for 9 Nm continuous torque, 22 Nm peak torque and 390 rpm rated speed at 48 V. CubeMars lists 0.51 Nm backdrive torque, 15 arcmin backlash and an operating-temperature range of −20 °C to 50 °C.

Timeline

  • CubeMars AK80-9 actuators power multi-terrain AI exoskeleton

    2025-07-19 - Demonstration - The Georgia Tech-led project, with Stanford and the University of Pennsylvania, used AK80-9 KV100 actuators in its lower-limb exoskeleton. The system estimated gait phase, detected slopes and switched assistance strategies across level ground, inclines, stairs and descents. The research appeared in Science Advances; CubeMars separately said it was collaborating with the team on next-generation integrated actuator modules.
