Latest advancements in noise and vibration simulation in support of electrical motors and power electronics.

Abstract

Electrical Motors specifically and Power electronics in general are mechanical systems that produce noise and vibrations. In most cases, the noise and vibration is unwanted for environmental, functional or comfort purposes. The presentation will address the different aspects of the noise, including cooling fan noise, unbalance noise and Electromagnetical noise. It will be demonstrated how recent technologies in acoustics can be applied to simulate, analyse and address the noise of electrical machinery. In a second part of the presentation the scope of the collaboration between JSOL and LMS will be highlighted in view of interfacing JMAG and Virtual.Lab products, resulting in a premier solution for Noise and Vibration analysis.
