Adaptive Method of Comparison to Identify for Force Ripples in Wavelet Coefficients of Two Types Linear Motors with Permanent Magnets

Abstract

This article proposes a numerical model of Permanent Magnet Linear Synchronous Motors (PMLSMs) for use as a tracking mechanism for the transport system. This paper studies the behavior under operating two types of linear motors to analyze and compare the system of forces and vibration levels to determine its efficiency as a transport system. The first model of motor has configuration of opposite poles and second has Halbach type configuration, are analyzed by the finite element method with commercial software FLUX™. The data of variation of force called ripple are analyzed with techniques for vibration signals using wavelet coefficients for classification of MatLab™ software to determine the concentration of vibrational energy levels and the parameters identified for each proposed linear motor.
