要約(英語): Nowadays, interior permanent magnet synchronous motors (IPMSMs) are widely utilized as traction motors. The permanent magnets used in IPMSMs are an important factor; thus, high-coercivity permanent magnets with lesser rare-earth elements are in development. This study investigated the performance of IPMSMs typically used in automotive applications modified to contain a strong magnet model (SMM). Rotor models with two permanent magnet arrangements, that is, a V-shaped single-layered permanent magnet structure (Type 1V) and a double-layered permanent magnet structure (Type 2D), were considered in this study. This paper discusses the characteristics of the analysis models based on the results of a two-dimensional finite element analysis. The maximum torques of Types 1V and 2D with the SMMs were approximately the same. In addition, the loss of Type 2D with the SMM was lower than that of Type 1V with the SMM at two evaluation points and under two driving schedules. Therefore, Type 2D was proved to be suitable for use with the SMM.
