 Description The Quarter Hollow Cylinder component models the leakage flux through a quarter-hollow cylinder air-gap, in the circumferential direction.
 Equations ${G}_{m}=2{\mathrm{\mu }}_{0}l\frac{\mathrm{log}\left(1+\mathrm{ratio}\right)}{\mathrm{\pi }}$ ${R}_{m}=\frac{1}{{G}_{m}}$ $\mathrm{\Phi }={\mathrm{\Phi }}_{p}=-{\mathrm{\Phi }}_{n}$ ${V}_{m}={V}_{{m}_{p}}-{V}_{{m}_{n}}={R}_{m}\mathrm{\Phi }$

Variables

 Name Units Description Modelica ID ${V}_{m}$ $A$ Magnetic potential difference between both ports V_m $\mathrm{\Phi }$ $\mathrm{Wb}$ 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

 Name Description Modelica ID ${\mathrm{port}}_{p}$ Positive magnetic port port_p ${\mathrm{port}}_{n}$ Negative magnetic port port_n

Parameters

 Name Default Units Description Modelica ID $l$ $0.1$ $m$ Axial length orthogonal to flux (=2*pi*r for cylindrical pole and r>>r_i) l $\mathrm{ratio}$ Constant ratio t/r_i ratio
