Abstract

Magnetic crane is one of the industrial applications of magnetic absorption, which uses an electromagnet to create the necessary force for lifting and moving objects. In this paper, the field analysis and design of an electromagnet are discussed. During the electromagnet analysis and design process, with special attention to leakage fluxes and fringing effects, a new magnetic equivalent circuit for an electromagnet is proposed. Also, the nonlinear behavior of the B-H curve of the ferromagnetic core and its saturation point are considered. Due to the various shapes of the ferromagnetic core, the U_I structure is selected with a symmetrical winding to reduce leakage flux and fringing effects. MATLAB software is used for analyzing and designing the electromagnet, and ANSYS Maxwell software is used to simulate its magnetic field. To verify the accuracy of the proposed method, the prototype was made of a magnetic crane with designed electromagnet. The comparison between measurement and simulation results shows that the error is less than 2%, which confirms the accuracy of the proposed method.
