Details

Built as a compact power module, AK60-39 V3.0 integrates the BLDC motor, planetary gearbox, and driver board into one unit.

A highly integrated, lightweight structure combines the motor, planetary gearbox, and onboard drive electronics to reduce wiring and save space.

Dual encoders support stable, accurate position feedback and improved anti-interference capability for demanding motion control.

Two-stage planetary reduction delivers a 39:1 gear ratio for higher torque output in robotic joints and actuators.


Black-and-white dual interfaces simplify power/CAN wiring and parameter tuning during debugging and integration.
