Abstract

The Boundary Element Method has been adapted to the 2D electromagnetic field analysis in the piece-wise homogeneous regions described by the Laplace, Poisson and Helmholtz partial differential equations. Two subregions described by the Helmholtz equation have been introduced. The axial component of the magnetic flux density on the surface of turbogenerator end laminations has been calculated using the above approach. The copper electromagnetic shield is placed between the clamping ring and pressure fingers in the afore-mentioned turbogenerator and the conducting elements has been considered as the Helmholtz subregions. The numerical results have been compared with measured ones.
