Abstract:
This research paper introduces a novel E-core designed Fault-Tolerant Flux-Switching Stator-PM (FTFSSPM) motor topology employing Multiple Permanent Magnet (MPM) materials. The primary objective of this design is to harness the synergy of the combined potential of different PMs as an alternative approach to address the high demand and cost volatility associated with Neodymium magnet (NdFeB) in PM motors. Additionally, incorporating E-Core design technology significantly enhances the fault-tolerant capabilities of the proposed motor topology, ensuring reliable performance even in the event of faults such as open circuits and short-circuits. The same motor topology is examined using various PM materials, including NdFeB, ferrite magnet (Y30BH), and Alnico magnet, to facilitate a fair and comprehensive design analysis. Furthermore, the results obtained through Finite Element Analysis (FEA) in the Ansys Maxwell electromagnet software reveal that the hybrid-PM combination of NdFeB and Y30BH delivers comparable and improved performance in terms of efficiency, output torque, torque density, and power density while maintaining minimal torque ripple when compared to the exclusive use of NdFeB. This outcome aligns with the research’s overarching objectives. Notably, the hybrid-PM configuration involving NdFeB and Alnico demonstrates commendable electromagnet performance. However, the synergy between NdFeB and Y30BH proves superior and on par with the performance achieved solely with NdFeB.
