Abstract: In this paper, the dynamic characteristics of a motor
which is usually examined through experiments after manufacturing the
prototype was analyzed using the non-linear finite element method (FEM)
based on 2-D numerical analysis in combination with the mechanical motion
equation. First of all, a 300 W surface permanent magnet (SPM) motor was
designed and the static characteristics were analyzed using the sinusoidal
current source. In addition, based on the phase voltage and the direct
current (DC) link voltage obtained from the static characteristics analysis
results, no-load speed analysis and the dynamic characteristics of loading
conditions were carried out. Through these analyses, it was possible to
predict the dynamic characteristics of a motor at the design process and to
verify the reliability of design.
