Details

A compact “two-in-one” actuator module that combines the motor and drive hardware for clean integration.

Designed for space- and weight-sensitive builds, the integrated module keeps the assembly thin and lightweight.


Planetary gearing provides a 6:1 reduction for higher torque density with low stated backlash.
