Overview
CubeMars AK70-9 Motor (AK70-9 KV60) is a highly integrated motor module with a built-in dual encoder. The compact integration combines a BLDC motor, planetary gearbox, and driver board into one unit for applications requiring precise positioning and control.
Key Features
- Highly integrated: built-in dual encoder (AK70-9 power module).
- Compact integration / lightweight design: combines BLDC motor, planetary gearbox, and driver board into one.
- Dual encoders, precise memory: retains position information even after power loss for accurate positioning.
- New upper computer easy operation: one-click parameter identification; switching between Servo and MIT modes; optimized interface for status monitoring (one-click start).
- Black & white dual interface: XT30 2+2 (black interface) combines power cable and CAN signal cable; CJT-3pin (white interface) for connecting to the upper computer to communicate and adjust parameters.

Details

An integrated actuator module that combines motor, gearbox, driver, and dual encoders for compact robotic joints.

Compact integration reduces wiring and saves space by bringing the BLDC motor, planetary gearbox, and driver into one unit.

Dual encoders help retain position information after power loss for more reliable, repeatable positioning.


Use the XT30 2+2 port for power and CAN, and the CJT-3pin interface to connect an upper computer for communication and parameter adjustment.
