Quarter Hollow Sphere

Description

The Quarter Hollow Sphere component models the leakage flux through a quarter hollow sphere air-gap.  The equations are

 ${V}_{m}=\mathrm{Φ}\cdot {R}_{m}$ ${V}_{m}\equiv {V}_{{m}_{p}}-{V}_{{m}_{n}}$ ${\mathrm{Φ}}_{p}+{\mathrm{Φ}}_{n}=0$ ${R}_{m}=\frac{1}{{G}_{m}}$ ${G}_{m}={\mathrm{μ}}_{0}\cdot 0.25\cdot t$

Connections
