Abstract: In order to analyse the electromagnetic field of the permanent magnet linear synchronous motor, the wavelet finite element method is applied to compute the electromagnetic field of it. First, the basic theory of Daubechies' wavelet is studied. Then the wavelet finite element model of the electromagnetic field of permanent magnet linear synchronous motor is constructed. Then simulation analysis of electromagnetic field is carried out by the wavelet finite element method, the traditional finite element method and actual test. And simulation results show that the wavelet finite element method has better convergence and can use fewer wavelet finite elements to get the higher computing precision for computing the electromagnetic field of the permanent magnet linear synchronous motor.

Keywords: electromagnetic field; permanent magnet linear synchronous motors; PMLSM; wavelet FEM; finite element method; simulation.
