Alternating and rotational loss prediction accuracy of vector Jiles-Atherton model

An anisotropic vector hysteresis model of ferromagnetic behavior under alternating and rotational magnetic field

“…The also classical Jiles-Atherton model (JA) has as well already been converted to a "type II" to generate vector results [23]- [25].…”

Finite Element Level Validation of an Anisotropic Hysteresis Model for Non-Oriented Electrical Steel Sheets

“…This paper considers AJAM explained in [30]-an improved extension of Bergqvist's vector JA model [32]. The model equations are re-summarized in the following:…”

“…Analytical representation of the anhysteretic characteristic is possible with the help of transcendental functions [25]. Nevertheless, to ease the computational burden, this paper applies bicubic splines [30]. Explicitly, in each rectangle k,…”

“…This paper presents the finite element analysis (FEA) of an RRSST sample-a NO silicon steel disk of grade M400-50 A. The FEA considers anisotropic and isotropic Jiles-Atherton (JA) hysteresis models [30]. The following four cases are considered for the FEA: flux density alternating in the RD, alternating in the 45 • direction (ALT45), alternating in the TD, and rotating in the counter clock-wise direction (ROT).…”

“…The following four cases are considered for the FEA: flux density alternating in the RD, alternating in the 45 • direction (ALT45), alternating in the TD, and rotating in the counter clock-wise direction (ROT). The anisotropic JA model (AJAM) utilizes the anhysteretic magnetization from alternating BH measurements in seven directions: 0 • , 15 • , 30 • , … , 90 • [30]. Moreover, the JA model's parameters vary as a function of the magnitude and polar direction of the flux density [31].…”
