This paper presents a high-speed 3 kW 80 krpm surface-mounted permanent magnet (SMPM) motor for compressor applications. The design procedure using finite element analysis (FEA) is presented with a particular focus on the efficiency calculation. The paper also aims to give general indications to provide a cost-efficient solution. A prototype is built and experimental results are given and compared...
In this paper, we investigate the impact of mechanical stress on characteristics of interior permanent magnet synchronous motors from both results of measurement and calculation. First, the basic experiments by using stator cores with/without shrink fitting of housing are carried out. The measured iron loss is compared with the calculated results obtained by combined stress and electromagnetic field...
