Details

CubeMars AK45-36 KV80 integrates motor, planetary gearbox, and driver into one compact actuator module to save space.

A three-in-one architecture combines the motor, planetary gear reducer, and integrated driver for simplified installation.

High torque density in a 340 g package helps build compact joints for robotic arms, humanoids, and mobile platforms.

Low-noise operation and smooth FOC control support precise motion tasks where small angle changes matter.

A 36:1 planetary reduction ratio delivers higher output torque at low speed for joint-style actuation.

Plug-and-play wiring brings CAN, UART, and 24 V power connections to accessible onboard connectors.
