“…The E_U, E_I, U_U and U_I structures are the most common geometric structures for determining the shape of a ferromagnetic core. In [3][4][5] using ANSYS software, these structures have been compared with each other in terms of leakage fluxes and fringing effects, and the U_I structure has been recommended as the most suitable type of them. Therefore, in this paper the U_I geometry is used for the core.…”

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.

Abstract-Electromagnetic Levitation System is commonly used in the field of train Maglev (magnetic levitation) system. Modelling Maglev system including all the magnetic force characteristics based on the current and position. This paper presents 2DOF model which represents a sample of uniform rigid plane body based on the functions of current and the air gap. The present work identifies the dynamic correlation of the levitation system of the Maglev using three sub-models. Lead controller is developed to achieve system stability by considering the system correlation of system moments and inductance variations. The control properties of the present model are obtained through SIMLAB microcontroller board to achieve the stable Maglev system.

Using nonintegrated multiple coils in an electromagnet is a way to manage energy and reduce maintenance costs. In order to model and analyze the lifting force and the magnetic field in different zone of the electromagnet, an exact magnetic equivalent circuit (MEC) is required. In this paper, an accurate MEC to analyze dual‐coil electromagnets is presented. MATLAB and ANSYS MAXWELL software are used to analyze the proposed MEC and simulate the magnetic field and the lifting force, respectively. In multi‐coil electromagnets, if a coil burns out, the electromagnet will still be able to lift the loads with a percentage of the nominal load weight. Also, it is only necessary to replace the burned coil, which reduces the maintenance costs of the electromagnet. Flexibility in winding excitation is another advantage of using multiple coils in electromagnets. In this case, one or more coils can be excited according to the weight of the load. This feature not only increases the lifetime of the coils but also reduces the energy consumption of the electromagnet and no need to use expensive power electronic converters to continuously control the current of coils. To evaluate the proposed MEC, the laboratory platform of an electromagnet was made to lift a load of 100 kg in the air gap of 2 mm and tested in two modes, single‐coil and dual‐coil. The analytical, simulation, and experimental results have very good agreement, indicating the high accuracy of the proposed MEC.
