Frequently Asked Questions

1.What is a Direct Drive Linear Actuator?

A Direct Drive Linear Actuator is a type of linear motion system that uses a motor to directly move a load without the need for intermediate components like gears, pulleys, or belts. This design reduces mechanical complexity, increases reliability, and improves efficiency by minimizing friction and backlash.

Direct drive actuators are known for their smooth, precise movement and are commonly used in applications requiring high accuracy, such as robotics, automation, and aerospace. They are also quieter and have fewer maintenance requirements compared to traditional actuators with mechanical linkages.

2.How to Select a Direct Drive Linear Actuator？

Selecting a Direct Drive Linear Actuator involves considering several key factors to ensure optimal performance for your application. First, assess the required force and load capacity—ensure the actuator can handle the weight and resistance of the load it needs to move.

Next, consider the stroke length, which determines how far the actuator can travel. Speed and precision are also critical; high-speed actuators are essential for rapid movements, while precision is important for tasks requiring exact positioning. Power supply should match the actuator’s voltage (e.g., 12V, 24V) and compatibility with your system. Additionally, consider the environmental conditions, such as temperature, humidity, and exposure to dust or chemicals. Finally, ensure the actuator meets your durability and lifespan requirements. For reliable options, platforms like JIECANG offer a range of high-performance direct drive linear actuators.

3.How Does a Direct Drive Linear Servo Motor (Actuator) Work?

A Direct Drive Linear Servo Motor (Actuator) works by using a motor that directly drives the linear movement of a load without intermediate components like gears or belts. The servo motor converts electrical energy into rotational motion, which is then directly translated into linear motion through a built-in linear shaft or linear encoder.

This system provides precise control of position, velocity, and force. The actuator’s feedback loop ensures accurate and continuous adjustments, making it ideal for applications requiring high precision and smooth motion, such as robotics, automation, and high-speed machinery.
