  • In this work we perform two models of Permanent Magnet Linear
    Synchronous Motors (PMLSMs). Both are analyzed by finite element method
    with different position angles of the magnets which are called skew
    angles. This article proposes a technique to determine the maximum and
    minimum levels of vibration produced by the presence of ripple on the
    thrust of PMLSM by the interaction between magnets and stator slots and
    the harmonic magnetic flux density in the air gap. The technique is
    defined by the analysis of the vibration signal produced in the PMLSM,
    applying the Fast Fourier Transform (FFT) with spectral analysis
    technique, as the application to rotating machines, to see which is the
    skew angle that produces lower levels of vibration.The proposed
    numerical model was analyzed with commercial software Flux ™ using the
    finite element method. The data analysis of vibrations caused by
    variations in the thrust of the model is done with commercial software
    MatLab ™.
