Calculation of scattering on the heads of teeth in asynchronous machines.
Abstract
It is shown that scattering by the heads of the teeth is fundamentally different from the differential. The method for calculating the conductivity of scattering by the heads of the teeth is considered on the basis of a numerical finite-difference method for solving a field problem. A refined formula for calculating the scattering conductivity over the heads of teeth is proposed, providing accuracy not lower than 5%.
