Abstract
A first design approach for an electrical machine need not be done with the efforts of detailed magnetic field considerations. Often a more pragmatic way already fulfills the desired accuracy. Performing fast by hand calculations depends on the data that is available; for e.g., the lamination geometry or material. This article provides a table for different electrical steels that can be used in the analytical calculation of magnetic circuits. In comparison with existing publications this article shows two-dimensional functions for the specific iron losses and the relative permeability. Both magnetic flux density and frequency are input variables.
