They are highly precise and efficient in their control and can perform high-precision movements within a small space.

Electric linear actuators are becoming more popular in modern equipment due to technological advancements, particularly in the automation, intelligent equipment and medical fields. Electric linear actuators are used in many systems due to their efficiency, precision control, and low maintenance. They also meet the requirements for miniaturization and fast response.

Working principle of electric linear actuator

Basic Principle

Electric linear actuators work on the principle that an electric motor generates rotary motion and then converts it to linear reciprocating motion using a screw or gear. The motor rotates the gear or screw, which then drives the piston or nut to move along the rail guide to achieve linear displacement. This mechanism is used for precise motion control in automation, robots, and precision equipment.

Components and Functions

Motor: A device that converts electrical energy into rotational motion.

Nut and Screw: Converts rotary motion to linear motion.

Guide rail: This is a guide that guides the nut, piston or sprocket to ensure accuracy in linear motion.

Limit switch: This is used to limit the movement of the motor by setting the maximum and minimum stroke values.

Feedback sensor: This sensor monitors the position of actuators and gives accurate feedback signals for controlling the movement.

Advantages and challenges of electric actuators linear

1. Advantages

Electric linear actuators have the advantages of high-precision control, low noise, easy integration and low maintenance requirements. They are able to provide stable and accurate linear motion in a variety of applications and are suitable for occasions requiring high precision and reliability.

2. Challenges

However, electric linear actuators may face load capacity and speed limitations in some applications. For tasks that require large thrust or fast movement, the performance of the actuator may not be sufficient to meet the requirements.

Criteria for selecting electric linear actuators

1. Selection factors

When selecting an electric linear actuator, several key factors need to be considered. Thrust determines the maximum load that the actuator can withstand, and the selection needs to be matched according to the actual load requirements. The stroke determines the maximum movement distance of the actuator to ensure that the displacement requirements of the application are met. Speed affects the response time and efficiency of the movement and adapts to different operating requirements.

The size must be compatible with the equipment space and structure to ensure effective use of the installation space. The power should match the power supply capacity of the power supply to avoid overload. Durability is related to the service life of the actuator, especially in high-frequency or harsh environments.

2. Installation and commissioning

When installing an electric linear actuator, first determine the installation location and secure the actuator. When connecting the controller, ensure that the power supply and cable match, and the controller settings must be consistent with the working requirements of the actuator. Then debug and check the stroke, speed and load capacity to ensure smooth operation. During the debugging process, it is necessary to adjust the limit switches and set the appropriate working range.
