Analyzing the advantages of linear actuators

When we talk about linear actuators, the first thing that comes to mind is the accuracy and speed of their operation, as well as the load and thrust of the linear actuator. One may ask, why is a linear actuator more expensive than a linear module? What are its core values? What are its advantages? The following points are summarized for your reference.

Linear actuators have many advantages, such as for high-speed, zero-maintenance, and high-precision requirements, linear actuators have unparalleled advantages. Linear actuators have unique characteristics that cannot be replaced by rotary motors.

Linear actuators have the following advantages:

1、Simple structure

As the linear actuator does not need to go through the intermediate conversion structure to produce linear motion directly, the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced, reducing the motion inertia and improving the dynamic response performance and positioning accuracy. The structure is simple and well-equipped, and its structure is more spatially compact compared to linear motor modules, with fewer accessories, optimized structure, integrated molding, small volume, and large thrust.

2、Fast response speed

High sensitivity and good tracking effect. The linear actuator eliminates the contact friction resistance between the stator and the stator, thus improving the sensitivity, rapidity, and servo performance of the system.

3、Safe and reliable

Long service life. Linear motor without contact power transmission, mechanical friction loss is almost zero, low failure rate, maintenance-free, safe and reliable operation, long service life. Linear motors are suitable for high-speed linear motion. Without the constraint of centrifugal force, ordinary materials can reach higher speeds. There is no wear and tear on the transmission parts, which can reduce mechanical loss and low noise, thus improving the overall efficiency.

4、Cost saving

As the linear actuator improves reliability, it can save cost and make production and maintenance easier. And Zhengke motors are a newly launched IP65 waterproof version.

5、Easy to adjust and control

By adjusting the voltage or frequency, or changing the secondary material, different speeds, electromagnetic thrusts can be obtained, suitable for more application scenarios.
