Selection of optimum device parameters for permanent magnetic field generation

Abstract

THE PURPUSE. To consider the fields of application of electromagnetic treatment of water systems. To analyze the modern literature on the use of constant magnetic fields for dehydration of oil-water emulsions. To develop the design of a device for generating constant magnetic fields and select its parameters. To select the electrical circuit for powering the device. To determine how the energy efficiency of the device changes with an increase in its overall dimensions. METHODS. When solving the problem, the KOMPAS-3D three-dimensional modeling system was used, the magnetic field induction was calculated using the PascalABC programming system, the optimal device parameters were selected using the Microsoft Excel program. RESULTS. The article describes the relevance of the topic, considers the distribution of the magnetic field in the device under development, determines the optimal design parameters for this device and selects the electrical power circuit. CONCLUSION. Calculations have shown that the coefficient taking into account the inhomogeneous distribution of the magnetic field in the device is 0.883. Using the KOMPAS-3D three-dimensional modeling system, a model of the device under development was builttaking into account the obtained relationships.When using a circuit with an uncontrolled rectifier and autotransformer, the power consumed by the device is 2.67 times lower than the power consumed by the device when using a circuit with a controlled rectifier and a transformer. Energy efficiency increases significantly with the increase in device performance.
