Abstract

The article explores the determination of NVH-relevant electromagnetic forces in PMSMs, a critical aspect of modern electrical machine design. It delves into the calculation of air gap force densities using flux density components and their transformation through 2D-FFT to reveal spatial and temporal harmonics. The method enables the identification of standing and traveling waves, crucial for predicting torque ripple and other NVH issues. The paper also addresses the impact of non-ideal influences like eccentricities and geometrical tolerances on NVH behavior, providing a comprehensive approach to predict and mitigate these issues in the digital development phase.
