Product Overview
Compact, high-density power
The CubeMars AK45-36 V3.0 KV80 packs a brushless motor, a 36:1 planetary gearbox and a driver into a highly compact all-in-one module. At just 349 g it delivers up to 24 Nm peak torque, giving a high torque density of roughly 68.8 Nm/kg.
Its dual-encoder architecture improves noise immunity and holds single-turn absolute position after power loss, so the joint returns accurately on startup without homing. Servo and MIT modes, auto PID tuning and full protection round out the package.
