Cardoso; João F. P. FernandesConference: Global Power, Energy and Communication Conference (GPECOM) (2020)(Check this article) Short Abstract: To analyze the impact of cobalt iron cores in the design of interior permanent magnet synchronous motors (IPSM) for competition electric vehicles, a spoke-type IPSM geometry is optimized considering FeSi and VaCoFe cores. It is shown that machines with VaCoFe core are a better alternative across both considered torque and efficiency ranges. VaCoFe can result in an estimated increase of up to 3% in efficiency for the same torque, or up to 70% torque increase for the same efficiency level.

Fernandes; P. J. da Costa Branco (copy-past the authors from IEEE site, it comes with links)Journal: IEEE Transactions on Applied Superconductivity (2021)(Check this article) Short Abstract: This paper proposes a novel methodology for calculating a space-varying permeability in HTS bulks, ensuring the same magnetic energy stored in E-J models at each infinitesimal volume, for the electromagnetic force calculation in HTS bulks.  The proposed method was validated using simulation and experimental tests based on YBCO/GdBCO permanent-magnet force interactions. These results show that, with a previous general study of the geometry to optimize, the equivalent model can be used for optimization purposes, greatly reducing the computational time.
