Journal ArticleDOI
Advanced High-Power-Density Interior Permanent Magnet Motor for Traction Applications
Ayman El-Refaie,James Pellegrino Alexander,Steven Galioto,Patel Bhageerath Reddy,Kum-Kang Huh,Peter de Bock,Xiochun Shen +6 more
TL;DR: In this paper, the authors provide details of the design, analysis, and testing of an advanced interior permanent magnet (PM) machine that was developed to meet the FreedomCAR 2020 specifications.
Journal ArticleDOI
Effect of Magnet Types on Performance of High-Speed Spoke Interior-Permanent-Magnet Machines Designed for Traction Applications
TL;DR: In this article, the authors compared the performance of different types of Dy-free and Dy-prosium (Dy-Dy) magnet types in terms of power density, efficiency, flux-weakening capability and magnet susceptibility to demagnetization.
Journal ArticleDOI
Development of a High Speed HTS Generator for Airborne Applications
K. Sivasubramaniam,T. Zhang,Murtuza Lokhandwalla,Evangelos Trifon Laskaris,James William Bray,B. Gerstler,Manoj Ramprasad Shah,James Pellegrino Alexander +7 more
TL;DR: The development of the generator is described and some key test results used to validate the design are presented, which indicate that the generator has a significant margin over the test points and that its performance is consistent with program specifications.
