Abstract
The vibration and acoustic behavior of electric machines is an important criterion in the design phase. The impact of the winding and the insulation on the eigenfrequencies, the eigenmodes and the damping of the stator is one of the main uncertainties. Therefore, in this work, the influence of a hairpin winding, insulated with two different insulation types, is analyzed. Four different stator specimens are examined by performing an experimental modal analysis and a FE harmonic analysis. On the basis of the results, equivalent material parameters for the homogenized winding, consisting of copper conductors and insulation material, are derived by comparing the simulation and the measurement results. The Young's modulus (also called the elastic modulus) is identified by performing a parameter fitting. A methodology for comparing and evaluating the measurement and the simulation results is presented. The resulting equivalent material parameters of the winding can be used for future calculations.
