ELECTRICAL AND ENERGY PARAMETERS OF AN INDUCTOR LOADED WITH STEEL BALLS
The article presents a method for calculating electrical and energy parameters of an inductor with dispersed loading in the form of a set of steel balls of the same diameter in the absence of electrical contact between them. A single steel sphere is represented as a set of disk segments. A numerical model is used to determine distribution of the magnetic field strength over the surface of the ball and dependence of the distribution of the volumetric power of heat release over the cross section of the ball. The obtained distributions of the parameters for the solid and segmented spheres have been compared, and a coefficient has been determined which takes into account the changes in the integral electrical parameters when the sphere is represented as separate segments. The article also presents the results of experimental studies which can be used to determine electrical parameters of an inductor loaded with steel balls at a fixed temperature. The measurement results have been compared with the results obtained during the simulation procedure.
