Paper Title:
Evaluation of Thrust Force and Positioning Accuracy of a New Linear Motor
  Abstract

A new linear motor based on the Sawyer principle is firstly introduced. Some important features of the linear actuator are discussed for better understanding of its performances and functions with absolute positioning. We investigated the static characteristics of the linear motor such as the relationship between the current and the maximum thrust force (I-F curve), the relationship between the displacement and the thrust force (D-F curve), and the positioning accuracy. The measuring methods for these characteristics are explained in detail. We analyzed the experimental data and evaluated the characteristics. We obtained that the suitable working current is 1A and the maximum thrust force is 15N for the linear motor. The positioning accuracy is ±12µm.
