Enhancement of Efficiency of the Magnetic Suspension of Belt Conveyor

摘要

Transportation of large pieces of rock hauled on the belt conveyor causes fatigue wearness of the belt rollers. It has been proposed to upgrade the system of magnetic suspension using alteration of the direction of the magnetization vector of the permanent and levitating magnets in conveyor where there are no load-bearing rollers, and there is dual-magnetic suspension. Three layout schemes of the permanent and levitating magnets with axial placement of the magnetization vector, with a layout of the vector at forty-five degrees angle and a Halbach array of five segments have been reviewed. For each scheme, distribution of the magnetic field in plane at 0,5mm distance from the surface of the permanent magnets has been obtained. The repulsive force at parallel position of the permanent and levitating magnets at a distance of 1 mm has been obtained.
