ACTILINK-JD

DYNAMIC ACTUATORS WITH SINGLE-STAGE PLANETARY GEARBOXES FOR HUMANOID AND QUADRUPED ROBOTS

Quasi-direct drive with a single-stage planetary gearbox, high-torque motor, and integrated SOMANET™ Circulo drive. Four sizes ranging from 78.5 to 120 mm outer diameter, with EtherCAT and Safe Motion via FSoE.

TECHNICAL DATA
ACTILINK-JD Actuators JD08, JD09, JD10, and JD12

AT A GLANCE

The ACTILINK-JD series combines a compact coaxial design with high torque density and a low-backlash gearbox. A single-stage planetary gearbox, a high-torque motor, and an integrated SOMANET™ Circulo drive ensure high dynamics, backdrivability, and reliability under mechanical load for humanoid robots, robotic dogs, and exoskeletons.

Single-stage planetary gearbox: coaxial design with low holding torque, quasi-direct drive with high dynamics and reverse drive capability.

Four sizes: JD08, JD09, JD10, and JD12, with maximum acceleration torque ranging from 17 to 102 Nm.

SOMANET™ Motion Drive: EtherCAT, high-performance motion control, high efficiency.

Functional Safety: STO and SBC as standard features; Safe Motion via FSoE as an option (SIL 3, PL e, Cat. 3).
