PM and hybrid excitation synchronous machines: Performances comparison

In this paper, a new topology of hybrid excitation synchronous machine (HESM) is presented. This kind of machine is well suited for hybrid vehicle applications. First of all, a summary description of the HESM is presented. A simplified analytic study based on reluctant network is presented. It is validated by finite element analysis and experimental measurements. The mechanical performances of the presented HESM are compared to a conventional permanent magnet synchronous machine (PMSM) designed for the same application.
