This paper addresses the issue of mitigating the noise emission of high-speed permanent-magnet (HSPM) machines. HSPM machines are increasingly used in a large field of applications for their power density and compactness. However, increasing the speed tends to intensify the noise emissions where more and more applications require a quiet operation. The focus of this paper is to propose a HSPM structure...
The interest in high speed electrical machines for automotive applications has increased recently. This includes electrically-assisted turbochargers (EAT), air compressors for fuel-cells and waste heat recovery (WHR) generators. For these kinds of application working in elevated temperature environments, the losses in the machine and in the power electronics should be carefully analyzed. In this context,...
