Why LG Actuator AXIUM
Leads in Robotics

Compact, efficient, and reliable — LG’s actuator supports advanced robotic performance through precision and control.

All-in-One
Compact Power

With unrolled segmented stator core, our actuator delivers higher torque density in a smaller footprint—same power, less size for compact, efficient robotic systems.

FAQs

Q.

What is an actuator and how does it work in a robot?

A.

An actuator is a key component that converts electrical energy into mechanical motion. In robotic systems, it drives joints and wheels with controlled precision, enabling machines to move and perform specific tasks as intended.

Q.

How does LG’s actuator improve energy efficiency in robotic systems?

A.

LG’s actuator recovers energy generated during deceleration through a regenerative system, extending operating time and contributing to more sustainable robotic operations.

Q.

How does LG’s actuator achieve compact yet powerful performance?

A.

With a distributed core motor design, the actuator delivers higher torque density, providing the same output power in a smaller and lighter structure.

Q.

In which types of robots can LG’s actuator be used?

A.

LG’s actuator applies to a broad range of robotic fields — from home and service robots that assist in daily life, to industrial and collaborative units used in manufacturing, as well as logistics and mobility robots operating in warehouses and delivery sites.

Its scalable design supports diverse payloads, joint types, and motion requirements across these environments.

Q.

How does LG maintain the reliability of its actuator products?

A.

Each actuator undergoes extensive testing for torque accuracy, thermal stability, and mechanical endurance to meet industrial-grade standards and ensure long-term dependability.

Q.

What should I consider when choosing an actuator for robots?

A.

Choose based on your robot’s purpose: torque & speed for performance, compact size for integration, energy efficiency for longer runs, and reliability for continuous operation.

Q.

Why are multiple sizes and customized actuators important?

A.

Robots will take many forms in daily life. Different joints need different sizes, and future applications will require tailored actuators for unique tasks and environments.
