Laminated structures can be represented computationally by the finite element method (FEM) using the homogenization procedure, which consists of the adjustment of equivalent orthotropic properties to a homogeneous structure.
The application occurs in stators of electric machines composed of stacked laminated disks connected to each other through windings and other fastening components.
This paper describes a method to the dynamic characterization of a typical laminated stator through the application of the homogenization technique to the magnetic core and consideration of the effect of winding contour conditions and screw joints.
Two simplified three-dimensional models for the stator were compared.
The first considers the application of a typical tightening of the fastening screws and the presence of a homogeneous isotropic volume representing the winding.
The second considers the effect of the boundary condition of the winding on the region of the teeth of the nucleus in order to reduce the degrees of freedom of the complete model.
The coupling between the components is accomplished through the application of modal synthesis methods, which require the definition of the surfaces and the type of connection between the components.
The obtainment of the set of equivalent orthotropic properties is based on the minimization of residues related to the difference between the natural and experimental frequencies in the range of 0 to 10 kHz.
This was carried out using the multiobjective genetic algorithm (MOGA) method used in conjunction with commercial Ansys® software.
Both models presented satisfactory experimental correlation.
The simplified model demonstrated limitations of representativeness emphasized in specific frequency bands.
