Abstract :
This paper presents the design optimization of air-cored linear permanent magnet synchronous motors. Reducing thrust ripple is the aim of optimization. In order to achieve this purpose some of motor dimensions are chosen as the design variables and are optimized using an analytical model and genetic algorithm method. The optimization results in a reduction of thrust ripple to ten percent of its initial value. The results of design optimization are finally verified by finite element method with good agreement
