modelHollowCylinderAxialFlux
(Hollow) cylinder with axial flux; fixed shape; linear or non-linear material characteristics
Extends from BaseClasses.FixedShape (Base class for flux tubes with fixed shape during simulation; linear or non-linear material characteristics), Modelica.Magnetic.FluxTubes.Icons.HollowCylinderAxialFlux (Icon for cylinder with axial flux).
Information
Please refer to the enclosing sub-package FixedShape for a description of all elements of this package and to [Ro41] for derivation and/or coefficients of the equation for permeance G_m.
Set the inner radius r_i=0 for modelling of a solid cylindric flux tube.
