Analysis of the Electromagnetic NVH of Electrical Machines

Stephan Guenther
AVL Software and Functions GmbH


The presentation deals with the electromagnetic NVH of electrical machines for electric vehicle application. It aims at presenting the current AVL-workflow for the calculation of NVH related issues in electrical machines and at discussing important time and spatial orders with regard to the NVH behavior. An in-house developed interior permanent magnet synchronous machine is used as example for the simulations. The simulation results are verified by additional NVH measurements on a test bench.
