Hollow Cylinder Axial Flux

(Hollow) cylinder with axial flux; constant permeability

Modelica Standard Library

	Description
	The Hollow Cylinder Axial Flux Reluctance Force (or Hollow Cylinder Axial Flux) component models the generation of a reluctance force from a flux tube consisting of a hollow cylinder with axial flux flow.

	Equations
	$B = \frac{Φ}{A}$ $F_{m} = \frac{1}{2} V_{m}^{2} \frac{{dG}_{m}}{dx}$ $G_{m} = μ_{0} μ_{r} \frac{A}{ℓ}$ $R_{m} = \frac{1}{G_{m}}$ $Φ = Φ_{p} = - Φ_{n}$ $V_{m} = V_{m_{p}} - V_{m_{n}} = R_{m} Φ$ $\frac{{dG}_{m}}{dx} = - μ_{0} μ_{r} \frac{A}{ℓ^{2}} \frac{d ℓ}{dx}$ $f_{flange} = - F_{m}$
