Abstract

Double-sided permanent magnet linear synchronous motor (PMLSM) is used in high precision manufacturing system. Reducing the higher harmonic components of the air gap magnetic flux density can significantly suppress the thrust fluctuation of the linear motor. In this paper, an unequal width Halbach magnet array is proposed. The FEA results shows that the harmonic component can be reduced by the an unequal Halbach magnet array with center aligned. On this basis, the parameters of the permanent magnet poles are optimized based on finite element parametric scanning. The optimization results show that the thrust ripple can be reduced by 89.6% by minimizing the total harmonic component. The new configuration can effectively suppress thrust fluctuation without changing the square shape of the permanent magnet, and has the characteristics of simplicity, effectiveness and low cost.
