Abstract

For the design of electrical machines, electrical steel BH curves are usually used in tabular or graphical form in magnetic circuit calculations. This is not convenient for the digitization of data and increases the requirement for computational accuracy. In this work, a partial approximation of the BH curves by the exponential function is proposed. The accuracy of the results obtained relative to the total approximation of these curves is demonstrated. The method for calculating the coefficients of the approximation functions is given. Application use of these curves is modeled in calculating the magnetic voltage of the trapezoidal-shaped stator tooth in AC machines. Finally, a numerical calculation example is carried out according to the proposed method.
