The effect of linear electric actuator on accuracy when used in combination with a precision servo reducer.
I. Introduction. Linear electric actuators and precision servo reducers are important drive components in the field of industrial automation and mechanical engineering. When these two are combined, they have a significant impact on the accuracy of the system. This article will detail the impact of this combination on accuracy and its related factors.
2. The influence of linear electric actuators on accuracy.
Resolution: The linear actuator has a high resolution, which means it is able to provide small changes in displacement, which increases the positioning accuracy of the system. By precisely controlling the displacement of the actuator, finer manipulation and adjustment can be achieved.
Repeatability: The high repeatability of the actuator ensures consistency and stability of displacement every time the same operation is performed. This is essential for applications that require high accuracy and consistency, such as assembly lines, measurement equipment, and more.
Linearity: Linear actuators have good linearity, that is, there is a linear relationship between their output displacement and the input signal. This enables the system to respond accurately to control signals and achieve high-precision position control.

3. The influence of precision servo reducer on accuracy.
Reduction ratio: Precision servo reducer increases the output torque by decreasing the output speed. This deceleration reduces the vibration and shock of the system, which improves positioning accuracy. At the same time, by selecting the appropriate reduction ratio, the dynamic response and steady-state accuracy of the system can be further optimized.
Return clearance: The precision servo gear unit has a very small return clearance, which means that there is almost no position error during commutation. This helps to improve the positioning accuracy and repeatability of the system.
Rigidity: The high rigidity of the servo reducer ensures that its deformation under load is minimized. This helps to reduce position errors caused by load changes and improves the stability and accuracy of the system.
Fourth, the advantages of combined use.
Complementary effect: The high resolution and repeatability of the linear electric actuator combined with the high rigidity and low backlash of the precision servo reducer achieve a further improvement in system accuracy. This complementary effect results in a higher overall performance of the combined system.
Dynamic performance improvement: The addition of servo reducer improves the dynamic response performance of the system. It can respond quickly and accurately to control signals to achieve high-precision, high-speed positioning and tracking. This is advantageous for applications that require fast response and precise positioning.

Reduced errors: Errors caused by insufficient performance of individual components can be reduced by combining them. For example, small displacement errors in electric actuators can be compensated for by the precise transmission of a servo reducer, thus improving the overall accuracy.
V. Conclusions. When linear electric actuators are used in combination with precision servo reducers, they have a significant impact on the accuracy of the system. By leveraging their respective strengths and complementing each other, this combination enables higher positioning accuracy, repeatability, and dynamic performance. In practice, the appropriate model and parameter configuration should be selected according to the specific needs to ensure the best performance of the system. With the continuous advancement of technology and the increasing demand for applications, this combination will play a greater role in the future, driving the development of industrial automation and machinery manufacturing.
