MAGNETIC IMPURITIES INFLUENCE ON MAGNETIC FLUX DENSITY IN INDUCTOR ACTIVE ZONE

The six pole inductor with magnetic impurities in active zone is investigated. The finite element method is used to solve magnetostatic 2-D problem. The symmetrical three-phase alternating current system is simulated to create rotational magnetic field. The influence of magnetic impurities to the magnetic flux density mean value and dispersion is investigated in the inductor active zone. The magnetic particles magnetic permeability influence to magnetic flux density is investigated. The active zone mean magnetic flux density value and dispersion are calculated for each time moment. The simulation results could describe the magnetic impurities behavior in the inductor active zone, also as allow choose the appropriate particles.
