Rezumat:

The known formulas for 2D „corner” and „constriction” permeances have been derived by using conformal mappings for infinite domains and can be applied only for enough large domains. In this paper, the problem is analytically solved for finite domains and new exact and approximate formulas are proposed. It is shown that for finite domains the corner and constriction permeances can be much smaller than in the case of infinite dimensions and the limits of applicability of simple exact formulas are determined. This offers the possibility to make more accurate analytical calculations of magnetic devices and better evaluate acting magnetic forces.

Cuvinte cheie: Conform mapping, “constriction permeance”, “corner permeance”, 2D electric and magnetic field.
