Abstract
AbstractThe accurate prediction of the structural properties of sheet‐layered lamination stacks in rotors and stators of electric motors is a challenging task due to the special layer design. The joining technology has a major influence on the individual sheet interactions and on the macroscopic quantities. Here, full‐surface bonded lamination stacks are considered for which equivalent linear transversely isotropic material parameters are determined by modeling the bonding varnish using Zero‐Thickness interface elements. It is shown that this procedure delivers comparable results to those obtained with traditional methods, like the rule of mixture or by modeling the adhesive layer with 3D continuum elements.
