Quarter Sphere

Leakage flux through the corners of a quarter sphere

Modelica Standard Library

	Description
	The Quarter Sphere component models the leakage flux through a quarter-sphere air-gap, from one corner to the opposite corner.

	Equations
	$G_{m} = \frac{77}{500} μ_{0} r$ $R_{m} = \frac{1}{G_{m}}$ $Φ = Φ_{p} = - Φ_{n}$ $V_{m} = V_{m_{p}} - V_{m_{n}} = R_{m} Φ$

Variables

$Φ$	$Wb$	Magnetic flux from port_p to port_n	Phi
$R_{m}$	$H^{−1}$	Magnetic reluctance	R_m
$G_{m}$	$H$	Magnetic permeance	G_m
