Abstract

In this work, a comparison between five different designs of ferrite-based High-Speed Permanent Magnet Synchronous Machine (HS-PMSM) for automotive application is presented. Particularly, the machine configurations are achieved by means of an analytical multi-parameter design procedure, which takes into account both mechanical and electromagnetic aspects. Thus, among the possible design configurations that satisfy all the constraints, the most suitable solution is selected by imposing the minimization of active volume, permanent magnet thickness, permanent magnet volume, current and active length respectively. Finally, the selected configurations are compared to each other and validated through Finite Element Analysis simulations, which are carried out by means of JMAG Designer and SolidWorks software.
