Details

A compact three-in-one actuator module that combines motor, planetary gearbox, and driver to save installation space.

Motor, gearbox, and driver are integrated into one unit to simplify assembly while keeping the drivetrain compact.

Designed for high torque density in a lightweight 200 g package, with up to 4.1 N·m peak torque.

Low-noise transmission supports ultra-smooth motion and fine positioning control for robotics applications.

A 10:1 planetary reduction helps boost output torque while keeping backlash controlled to 18 arcmin.

Plug-and-play wiring includes labeled UART and CAN interfaces, 24V power input, and a 14-bit single-turn absolute encoder.
