Abstract

The paper reviews the progress in understanding and modeling the noise and vibration and the stray fields produced by electric machines. In machines that are already quiet, numerical methods are necessary to find the smaller sources of vibrations or emitted electrical signals. Several examples are given for permanent magnet machines and induction motors.
