The past 30 years have been an exciting period with tremendous advances in the development of interior permanent magnet (IPM) electrical machines. Over this period, the interior permanent magnet synchronous motors (IPMSM) have expanded their presence in the automotive marketplace of high-efficiency electric traction drives for the latest generation of hybrid Electric Vehicles (HEV) including high speed trains. Closer examination reveals that several different knowledge-based technological advancements and market forces have combined to accelerate the development of the impressive IPM drives technology. The purpose of this paper is to provide a short statement on impacts of the various factors that lead to the current state-of-the-art of IPM motor technology. This paper illustrates the application success of IPM technology for HEV traction drives and rail transportation system including cost and reliability.
