Generation process of magnetic noise and vibrations

This technical bibliography comes from EOMYS technical training on the physical generation process of electromagnetic noise and vibrations. It is regularly updated based on EOMYS consulting experience in the assessment and mitigation of magnetic noise problems in electrical machines and drives.

Electromagnetic noise and vibration levels must be taken into account starting from the conceptual design phase of electric machines. High magnetic noise levels can be produced by different types of excitations (e.g. radial, tangential, axial forces) and different transfer paths (e.g. inner Vs outer borne noise, air-borne Vs structure-borne noise). This different paths can be analyzed using numerical simulation with Manatee e-NVH software for an efficient analysis of the noise mechanism.
