Extensive Applications of Long-travel Linear Actuators

Ⅰ.Application Background and Limitations of Traditional Transmission

 

In the era marked by rapid advancements in industrial automation, the linear actuator assembly has stood out with its excellent performance, establishing itself as an indispensable component across domains such as precision manufacturing and semiconductor processing. Compared with traditional components like linear screws, coils, and strip modules, the linear actuator excels remarkably in critical areas including motion speed, repeat positioning accuracy, and service life. It can achieve high-speed single movements and precise multiple positioning.

 

Conversely, traditional transmission methods such as linear screws, belts, and rack-and-pinion gears face significant limitations in long-travel applications. They struggle with speed constraints and limited travel ranges while mechanical structure-induced transmission errors hinder high-precision requirements. Additionally, they present challenges in processing and manufacturing; prolonged use can lead to wear and deformation that compromise equipment stability and production efficiency. 

 

Ⅱ.Main Advantages of the Linear Actuators

 

1. Efficient Transmission: Adopting a special direct drive structure, the high-precision linear actuator eliminates intermediate transmission components and removes efficiency losses during the transmission process, significantly improving the energy utilization rate.

 

2. Precise Control: The direct drive mode avoids transmission gaps and errors in the screw mechanical structure. Combined with a closed-loop feedback control system using a grating or magnetic grid, it can achieve high-precision motion control at the micron or even nanometer level.

 

3. Reliable and Durable: With no contact-based transmission occurring between the stator and mover components, fundamentally avoiding wear and deformation issues, significantly improving the reliability and stability of the linear module system, and reducing maintenance costs.

 

4. Infinite Expansion: The stator of the linear actuator possesses the theoretical capability for infinite splicing and integration, rendering the module's travel unrestricted and allowing it to adeptly accommodate a diverse array of long-distance motion requirements.
