This article presents and validates a method for early estimation of the high-frequency impedance response for a real permanent magnet synchronous machine. The main contribution of this work lies in the simplicity of the data required to tackle the prediction, which do not require any experimental tuning or 3-D simulations. The required inputs for the method are the 2-D cross section of the machine and the material characteristics of the conductors, insulation, and iron laminations. An approach using the finite element method coupled with a circuit simulator is utilized to obtain the machine common-mode and differential-mode impedances over a broad frequency range. Experimental measurements are performed up to the resonance band to validate the methodology. In addition, the influence of the machine rotor and housing on the impedance curves is experimentally assessed. A machine with concentrated winding is used as a case study machine to test the model.
