Abstract

In this work, it was used the ANSYS Program to get the natural frequency, where the results are showing the first eight natural frequencies and which are tabulated in Table (2). The table also shows results obtained from using triangular elements as well as a finer mesh of quadrilateral elements. The results were obtained using 384 quadrilateral elements, it wasn’t different so much from those that use 1280 elements. This again shows that the triangular elements are less accurate than the quadrilateral elements. Note that the mode shapes obtained in the three analyses are nearly the same.

Keywords: Micro-motor, Natural frequency, ANSYS, Finite Element.
