Abstract
For electric motors light weight construction is becoming increasingly important, therefore the dynamical behavior of the lamination stack has to be known. The stacking of a lot of sheets has a relevant influence onto the behavior of the whole motor due to significant contact characteristics between the sheets. In this paper quasi-static tests are performed to identify this characteristic. At first a load representing the packaging process is applied onto the stack. Thereafter a cyclic load is superposed to show the forces during the motors life. With these quasi-static tests elastic and plastic effects and a hysteretic behavior are detected. These nonlinearities are referring to the sheet's roughness, the surface waviness and the existence of a coreplate varnish. In the modeling of the stiffness the roughness parameters are used. Based on the quasi-static model and with dynamic tests it is possible to identify the dynamic characteristic of the lamination stack.
