Comparison of Electromagnetic Force Characteristics and Experiment of Pitching Moment in Permanent Magnet Linear Synchronous Motor According to the Moving Iron Core and Stator Topology Lee, Seung-Han; Cho, Han-Wook; Khim, Gyungho; Oh, Jeong-Seok;
This paper presents the characteristic analysis and experiment of force characteristics in permanent magnet linear synchronous motor for accuracy prediction of linear motion machine tools. In particular, the pitching moment resulting from attraction force ripple has been analysed and tested. Firstly, we analysed the characteristics of detent force, attraction force, and pitching moment in permanent magnet linear synchronous motor according to the design techniques such as auxiliary teeth, chamfering, and permanent magnet skewing. In addition, we suggested the experimental set for measurement of pitching moment. Finally, the results from measurement shows the good agreement with those obtained from finite element analysis results.
