What exactly is an “AK power module”? CubeMars’ official explainer walks through the three compact members of the family - AK40-10, AK45-10 and AK45-36 - and the architecture they share: brushless motor, planetary gearbox and built-in driver in one sealed unit.
What the Video Shows
The video explains how the integrated architecture enables smooth, reliable motion for applications ranging from compact robotic joints to heavy-duty mechanisms, and why plug-and-play wiring changes the integration calculus for small teams.

Engineering Context
The interesting spec here is the spread: from the AK40-10’s 4.1 Nm peak to the AK45-36’s 24 Nm peak in the same Ø53 mm-class footprint, achieved mostly by the gearbox ratio. That lets a team scale joint torque without changing wiring conventions, driver tooling or form factor.

Conclusion
For compact robots that need several joint classes from one ecosystem, the AK power-module trio covers a 6:1 torque range in matching packages - a practical argument for standardizing early.
