Research of influence of elements shape of a multicomponent lamellar matrix of polygradient electromagnetic separator on its strength characteristics. For analysis of magnetic field distribution in working area of electromagnetic separator the finite element method has been used, implemented in ELCUT 5.6 software package. A numerical-field analysis of magnetic field distribution in working interpolar zones of matrix with a polygradient medium on the basis of inserts in form of an isosceles trapezium and triangular plates with a rounded apex has been carried out. According to analysis results, the maximum values of power characteristics of electromagnetic polygradient separator have been established. For a multicomponent lamellar matrix of polygradient electromagnetic separator certain geometrical dimensions of matrix elements of various shapes, at which power characteristics of device acquire the maximum value have been defined. The results of research can be used for improvement of power characteristics of basic design of electromagnetic polygradient separator

Abstract The paper discuss a problem of determination of inductances for AC machine windings when saturation of magnetic circuit is not neglected. For such cases, computation of magnetic field distribution in the machine magnetic circuit is a starting point for post processing procedures leading to various values, among others the co-energy in a given area and linkage fluxes of windings. This paper shows how to determine winding inductances in a nonlinear magnetic circuit from these two values and also how to compute directly nonlinear inductances. Problem is not trivial because such inductances are not uniquely determined as for linear case. In the paper a definition of nonlinear inductances is proposed which makes the choice unique.
