Du, Yunlu (author), Huang, Yunkai (author), Guo, Baocheng (author), Djelloul-Khedda, Zakarya (author), Peng, Fei (author), Yao, Y. (author), Dong, J. (author)In this article, a nonlinear semianalytical model (SAM) is presented to predict the magnetic field distribution (MFD) and electromagnetic performances (EPs) in the cubic spoke-type permanent magnet (PM) machine. To model the rectangular PMs, the rectangular PM is simplified as a combination of fan-shaped regions with different arc angles....journal article 2024

Du, Yunlu (author), Huang, Yunkai (author), Guo, Baocheng (author), Peng, Fei (author), Yao, Y. (author), Dong, J. (author)This article proposes a hybrid analytical model (HAM) for predicting ac copper losses in hairpin windings. The HAM combines the nonlinear semi-analytical model (SAM) and the 1-D ac copper loss computation model to solve the inaccurate boundary solutions of the 1-D ac copper loss computation model when magnetic saturation occurs in the stator...journal article 2023

Du, Yunlu (author), Huang, Yunkai (author), Guo, Baocheng (author), Peng, Fei (author), Yao, Yu (author), Dong, J. (author)In this article, a new analytical model for predicting the magnetic field of the U-shaped interior permanent magnet motor (IPMM) is proposed. In the polar coordinates, rectangular permanent magnets are equivalent to the combination of consistent fan-shaped subdomains, and after that, the Laplace or Poisson equation of each solution domain can...journal article 2023
