Multiobjective Design Optimization of Ironless Permanent Magnet Linear Synchronous Motors for Improved Thrust and Reduced Thrust Ripple

摘要：

　　In order to achieve high thrust density and low thrust ripple simultaneously,a multiobjective optimization design method is applied to ironless permanent magnet linear synchronous motor with non-overlapping windings.On the basis of the magnetic field analysis model,the analytical formulae of key parameters such as No-load back EMF,thrust per copper quality and thrust ripple was deduced.Further,a multiobjective optimization is carried out by genetic algorithm to search for the optimal design variables.The design optimization is verified by 2-D Finite Element analysis and experimental results of the prototype.
