The article deals with the results of research in 2018, the department of electromagnetic systems. It is reported that analytical methods for calculating electromagnetic fields in electromagnetic systems are developed. The methods simulate current contours in space to create alternating magnetic fields and induce currents in electrically conductive regions. It is shown that magnetic forces and heat distribution in the inductor for heating moving ferromagnetic strip are investigated. Inductor for heating ferromagnetic strip is without ferromagnetic core, and it takes into account the finite width of the strip. Much attention is given to the ability to heat ferromagnetic strip with a satisfactory uniformity in width. The conditions for electrodynamic stabilization of strip at the center of the air gap have been determined by frequency control. Also this article deals with the analytical method for calculating electromagnetic fields of arc-stator axial induction disk motors with bimetallic rotors. This method takes into account the real spatial current distribution three-phase winding of two arc-stators on both sides at disk rotor. The method allows calculating three-dimensional electromagnetic field distribution in air-gap between two stators, and it takes into account the linear speed of moving disk rotor. It is spoken in detail about the analytical expressions for the calculation magnetic forces in the air gap. It should be noted that energy characteristics and magnetic forces of the gearless axial arc-stator disk motor for powerful ball mills are calculated by the developed analytical method. The paper gives valuable information about experimental studies of the barrier discharge to the water surface. Experiments shows the existence of a uniform barrier discharge to the water surface at atmospheric pressure, at the fixed length of the voltage pulse region and at fixed values of the electric field in a gas space. The complex of works, which substantiates in detail the possibility and expedient ways of increasing the efficiency of using the installed source power, are done. The power source consists of the transforming element with sectional winding in the transformer-key actuating structure of the AC voltage stabilizer. Reference 34, figures 24, tables 3.
Key words: induction heating, axial arc-stator induction motor, uniform barrier discharge, transformer-key actuating structure.
