Mapping of magnetic properties for simulations of high-Temperature electromagnetic applications
(2017) In COMPEL - The International Journal for Computation and Mathematics in Electrical and Electronic Engineering 36(2). p.546-554- Abstract
Purpose -The purpose of this paper is to investigate the added value of using temperature-dependent electric and magnetic properties in high-Temperature electromagnetic simulations. Design/methodology/approach - In this work, the electromagnetic properties of Domex 420, SSAB, have been characterized as a function of the temperature, from room temperature to 900°C. The measurement of the electric and magnetic properties was performed inside a vacuum furnace at a number of discrete temperature steps, with particularly small intervals around the Curie temperature. A simple transient multi-physics model was used to investigate the impact of the measured properties in three different representations. Findings - In certain intervals, a... (More)

The measurement of the electric and magnetic properties was performed inside a vacuum furnace at a number of discrete temperature steps, with particularly small intervals around the Curie temperature. A simple transient multi-physics model was used to investigate the impact of the measured properties in three different representations. Findings - In certain intervals, a simplified approximation of the properties produces accurate results, while fully parametric representation is beneficial when heating above the Curie temperature. Originality/value -Temperature-dependent electromagnetic properties are rarely found, especially in an easy-To-use form. Using parameterized temperature-dependent approximation of key properties shows noteworthy differences in the outcome of high-Temperature electromagnetic modeling.
