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.

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.

“…Thompson Corporation studied the structure and size parameters of the electromagnetic valve through a large number of experiments, and optimized the dynamic and static characteristics, volume and weight of the electromagnetic valve [11,12]. Other studies optimized structural design or the dynamic characteristics of electromagnetic valve by selecting soft magnetic materials with different B-H curves [13][14][15][16]. For example, Wang et al [17] used AL-Fe material to prove by experiment that new soft magnetic material could significantly improve the performance of high-speed electromagnetic digital valve.…”

Due to the influence of material characteristics and winding power, single output electromagnet has limited ability to improve the dynamic characteristic of electro-hydraulic valve. Therefore, an electromechanical converter with double push rods is proposed in this paper, which can simultaneously output two electromagnetic forces, can push or pull the valve core and sleeve according to the current direction and realize rapid operation of load. According to the electromagnetic principle and the magnetic circuit analysis method, the mathematical model and equivalent circuit of the electromechanical converter with double push rods are established. Through the finite element simulation model of the electromechanical converter with double push rods with the same magnetization directions, the changing rules of its magnetic field distribution and force-displacement behaviors are studied and analyzed. According to the analysis results, the electromagnetic mechanical parameters and mechanical structure of the electromechanical converter with double push rods are determined, and the prototype is made. The test platform for the push-pull characteristics of the electromechanical converter with double push rods is built, and its static and dynamic characteristics are tested and analyzed. The results show that the thrust and pull output characteristics of the internal and external push rods are basically consistent with the simulation output, and proportional to the current density of the coil; the push-pull hysteresis of internal and external push rods output force is less than 5%; and the dynamic time response characteristics of the displacement and force are obtained. The hysteresis effect of output force is improved effectively through the H bridge drive control circuit modulated by PWM. Compared with the displacement response of a singlewinding electromagnet with a similar volume, it can effectively improve the dynamic displacement response. Followup work will further optimize the structure of the electromechanical converter and test the corresponding pilot valve. The research results provide a new theory for improving the output characteristics of electro-hydraulic pilot valve and have an extremely high engineering application value and broad application prospect.
