High-Precision Micro Servo Electric Linear Electric Cylinder Actuator for Robotics
● Introduction
The actuator integrates a coreless (hollow cup) motor, a precision reducer, a screw-driven mechanism, a sensor, and a closed-loop control system. It offers a compact size, high power density, and excellent precision, making it suitable for precise servo control at any point within its stroke. Thanks to the built-in absolute position sensor, position data is retained even after power loss, eliminating the need for homing.
Features
The integrated drive and control architecture combines a precision reducer, coreless motor, and control system, offering a significantly smaller footprint than traditional cylinders.
The flat design (e.g., only 44 mm thickness in the LAS series) makes it ideal for installation in tight or constrained spaces.
● Power performance
Thrust capacity ranges from 68 kgf to 80 tons, with smaller models supporting up to 25 kg loads.
The planetary roller screw mechanism delivers a service life of over 2 million cycles, offering high rigidity and long-term durability.
Advantages
● Precision control
Repeatability reaches ±0.02 mm, with top models achieving accuracy up to 2 µm.
Supports four control modes: position, speed, force, and hybrid force-position, enabling precise pressure control and flexible contact.
● Dynamic response performance
Maximum speed reaches 200 mm/s for small models and up to 70 mm/s for standard models.
In force control mode, it can stably output micro-forces as low as 0.005 N, ensuring protection for delicate or fragile workpieces.
● Scenario adaptability
The actuator features a multi-interface design (flange, threaded, spherical bearing, etc.), allowing for flexible and modular integration.
Supports synchronized operation of multiple units, making it ideal for clustered or parallel deployment in industrial environments.
