Abstract

Aiming at the issue of significant thrust ripple in permanent magnet synchronous linear motors (PMSLM), a thrust ripple suppression method focusing on the stator side is proposed. First, a tubular permanent magnet synchronous linear motor(TPMSLM) with a 10-pole/12-slot Halbach magnetized array is preliminarily designed. Second, the effects of typical optimization schemes on the thrust ripple and its dominant harmonic components are analyzed. Finally, a genetic algorithm is applied to optimize the structural parameters. The results demonstrate that individual strategies can reduce the thrust ripple by up to 86%, while a combined approach achieves a remarkable reduction of 94.9%, indicating significant suppression effectiveness. The described measures for reducing the end force can serve as a valuable reference for linear motor design.
