Which is more accurate, a linear motor or a servo motor? This article compares resolution, repeatability, absolute positioning, and dynamic tracking from an engineering practice perspective, and includes parameter tables and selection procedures. It covers everything from screw lead and encoder conversion to thermal expansion.

How to choose between ball screws and roller screws? This article provides a complete analysis, covering contact type, efficiency, speed, L10 life, and preload examples from 0.02C to 0.1C, with load-speed diagrams and case studies of high-load injection molding machines.
