Comparison of Characteristics According to Permanent Magnet Arrangement of Permanent Magnet Linear Synchronous Generator

This study focuses on the comparative analysis of permanent magnet linear synchronous generators (PMLSG) with different magnetization arrangements. Using finite element analysis (FEA), this paper compares the performance analysis according to three magnetization arrangements of PMLSG with parallel, Halbach, and axial array PM. Comparison models are designed with identical rated output power, overall dimensions, air gap, and stator geometry to ensure reliability of comparison results. An experimental setup, including a rotary motor and a slider-crank mechanism, was developed to simulate wave motion and validate the FEA models. Comparative analysis between FEA results and experimental data demonstrated a high degree of correlation, affirming the validity of the analytical models.
