Wavelet Transform Application in End-effect Analysis of Linear Motor

DU Wen-yan,BI Lei,LI Chang-jiu(Department of Electrical and Electronic Engineering,Chengde Petroleum College,Chengde 067000,Hebei,China)  
End-effect is a main reason of influence on the characteristic of linear motor,and its direct impact is non-stable and undulate edges magnetic field.The wavelet transform is applied to study the end-effect of linear motor in this paper.Traditional analysis method is based on the Fourier transform,but it has localization contradiction of time-domain and frequency-domain,and some message while analyzing non-stable signal will be usually lost.Therefore,it is necessary to research a new method that can solve this problem reasonably and effectively so as to improve linear motor function.
