Abstract:
Recently, permanent magnet (PM)-assisted reluctance (PMAREL) machines are gaining
increasing attention for traction applications to reduce magnet consumption. In
this article, a comprehensive design methodology is applied to design a PMAREL
machine for an electric vehicle (EV) propulsion application. The design method
includes both electromagnetic and mechanical analyses. A finite element analysis
(FEA)-based differential evolution (DE) algorithm is adopted to find the best
reluctance (REL) rotor geometry. The PM dimensions are calculated analytically,
which allows a fast identification for the initial design. An FEA model for
mechanical analysis is developed, and some remedial techniques are adopted to
improve the mechanical stress. The design procedure starts with the selection of
the stator split ratio. Then it continues with REL optimization and PM dimension
determination. Finally, the rotor structure is modified iteratively based on
electromagnetic and mechanical performance. FEA validations show that the
designed PMAREL motor satisfies the requirements of the targeted propulsion
application.
