Magnetic Material with Parameter-based Hysteresis

Modelica Standard Library

	Description
	This magnetic material uses Everett functions to define the B-H hysteresis curve. This material can be used by the TellinenEverett component in the Magnetic > Shapes > Hysteresis palette; the instance name of material should be copied to the material (mat) parameter of the component, and possibly used in the sigma ( $σ$ ) parameter, if eddy currents are modeled.

Parameters

Name	Units	Description	Modelica ID
$H_{c}$	$\frac{A}{m}$	Major loop coercivity	Hc
$H_{sat}$	$\frac{A}{m}$	Hysteresis region is $- H_{sat}$ to $H_{sat}$	Hsat
$K$	$1$	Slope in saturation region is $μ$ 0K_	K
$M$	$1$	Related to saturation value of magnetization	M
$p_{1}$	$\frac{m}{A}$	Sharpness of major loop	p1
$p_{2}$	$\frac{m}{A}$	Sharpness of major loop	p2
$q$	$\frac{m}{A}$	Slope of the straight region in the vicinity of $H_{c}$	q
$r$	$1$	Proportion of the straight region in the vicinity of $H_{c}$	r
$σ$	$\frac{S}{m}$	Electrical conductivity of material	sigma
