Analysis of the Accuracy of the Standard Elements Method when Modeling the Magnetic Field in Parts of Electrical Machines with Narrow Elements, Angular Zones and Oscillation in Conditions at the Border

a variation in the error of calculating the magnetic field of electrical machine parts by standard elements method and finite elements method is analyzed under the influence of such factors as the presence of narrow inclusions in the calculation area, conditions oscillation at the border, variation of magnetic characteristics of materials. The error of vector potential values is estimated at contr...
