Development of flux reversal linear synchronous motor for precision position control

This paper introduces design and analysis of two different flux reversal linear synchronous motor(FRLSM) by 2D finite element method(FEM). The analysis models are optimized by response surface methodology(RSM) for a quantitative comparison. Analysis results show that the proposed FRLSM with multiple auxiliary salient poles effectively increases thrust. Magnetic unbalance reduction design is also suggested for the proposed FRLSM. A prototype of the proposed configuration is made and experimental results validate the design and analysis.
