Electric actuator LA series

linearcylinderDC

● Introduction The micro servo electric cylinder linear actuator is a compact and integrated linear servo system. It combines a servo motor, sensor, encoder, and precision linear transmission mechanism to enable high-precision displacement and force output via digital control. Serving as a core motion component in advanced electromechanical systems, it is widely used in robotics, medical devices, and industrial automation equipment. 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 ● ‌Structural design‌ 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.
