Abstract
The prediction of the vibration behavior is one crucial part of the design process for electric machines. The impact of the winding and the insulation on the stator's eigenfrequencies, eigenmodes and damping is not sufficiently analyzed. In this paper, the influence of a round wire winding and two different insulation techniques on the vibration behavior is studied. A methodology is presented to compare the measurement results of an experimental modal analysis with the simulation results of an FEM harmonic analysis. The vibration behavior of a blank stator lamination, a stator lamination with an uninsulated winding, an impregnated winding and a potted winding are analyzed. To determine equivalent material parameters for the slot filling, consisting of copper conductors and insulation material, the simulation and measurement results are compared. The Young's modulus of the slot filling E is identified by performing a parameter fitting. The Sum-Transfer functions, the eigenfrequencies, the damping and the eigenmodes are presented for the measurement and the simulation with the determined equivalent material parameters. The equivalent material parameters can be used for future calculations.
