| Abstract | Exact analytical formulae suitable to integrate the boundary quantity over a rectangular boundary element are given. They can be used in algorithms of the boundary-integral technique when some field quantity at the vicinity of the boundaries is searched for. The special computer test software was accomplished which enabled to compare the approximate integrations by Gauss quadrature to those ones obtained by the exact formulae. The error of the numerical approach increases significantly when a distance of field points from the boundary element becomes comparable with the size of it. For the larger distance, both kind of integration are equivalent. The above statement seems to be important when the boundary-integral technique should be applied to compute the magnetic field within the air gap of electric machines. |
