Improved formulations for rotational core losses in rotating electrical machines
Jianguo Zhu,V.S. Ramsden +1 more
TL;DR: In this paper, the rotational hysteresis, eddy current, and excess losses in electrical sheet steels with circular and elliptical rotating flux density vectors are reported, together with the finite element method to calculate the core losses in rotating electrical machines according to the distribution of the rotating magnetic field.
Journal ArticleDOI
Design of an in-wheel motor for a solar-powered electric vehicle
TL;DR: In the 1996 Darwin-Adelaide World Solar Challenge solar car race, an in-wheel electric motor for the solar-powered vehicle Aurora as discussed by the authors was designed to be more efficient (97.5% compared to 92-95%) and lighter than all other direct-drive motors.
Journal ArticleDOI
A generalized dynamic circuit model of magnetic cores for low- and high-frequency applications. I. Theoretical calculation of the equivalent core loss resistance
TL;DR: In this article, the theoretical calculation of the equivalent core loss resistance for a dynamic magnetic core loss model is presented, which incorporates the effects of both the classical eddy current and anomalous losses.
Journal ArticleDOI
A generalized dynamic circuit model of magnetic cores for low- and high-frequency applications. II. Circuit model formulation and implementation
TL;DR: In this paper, the authors describe the formulation and implementation of a generalized dynamic magnetic core circuit model suitable for both low and high-frequency applications, which is modeled by a simple ladder network consisting of nonlinear inductors and resistors.
Journal ArticleDOI
Harmonic filtering of high-power 12-pulse rectifier loads with a selective hybrid filter system
TL;DR: This paper presents a selective AF filter control system and simple hybrid filter topology suitable for the compensation of high-power 12-pulse rectifier loads and the importance of delay-time compensation is discussed.
