Publikováno v: 2020 IEEE Energy Conversion Congress and Exposition (ECCE).

While accuracy requirement for simulation-based efficiency map becomes high for traction motors which have high efficiency over wide drive range and where even a small improvement in efficiency is critical, their accuracy level has not been well stud

Autor: Takashi Yamada, Hiroyuki Sano, Kazuki Semba, Hirokatsu Katagiri

Publikováno v: 2017 18th International Symposium on Electromagnetic Fields in Mechatronics, Electrical and Electronic Engineering (ISEF) Book of Abstracts.

In order to calculate the copper loss calculation with coil end effect in a practical computation time, the zooming method, which is one of the model reduction methods, is applied to the analysis of an three-phase synchronous motor. Moreover, the fas

Publikováno v: IEEE Transactions on Magnetics. 49:1581-1584

We present a parallel multithreaded incomplete Cholesky-conjugate gradient (ICCG) solver for a linear system derived from a finite element electromagnetic field analysis. Algebraic block multicolor ordering is introduced to parallelize the solver wit
