	Description
	The Quarter Hollow Cylinder component models the leakage flux through a quarter-hollow cylinder air-gap, in the circumferential direction.

	Equations
	$G_{m} = 2 μ_{0} l \frac{\log (1 + ratio)}{π}$ $R_{m} = \frac{1}{G_{m}}$ $Φ = Φ_{p} = - Φ_{n}$ $V_{m} = V_{m_{p}} - V_{m_{n}} = R_{m} Φ$

Variables

Name	Units	Description	Modelica ID
$V_{m}$	$A$	Magnetic potential difference between both ports	V_m
$Φ$	$Wb$	Magnetic flux from port_p to port_n	Phi
$R_{m}$	$H^{−1}$	Magnetic reluctance	R_m
$G_{m}$	$H$	Magnetic permeance	G_m

Connections
