Abstract. The modern level of development of technique even more expanded a scope of electrical devices with levitation elements, used for exact stabilizing of an alternating current in adjustable loadings, automatic monitoring of not electrical parameters of technological processes, etc. Analytical expressions for parameter optimization and analysis are derived. The presence of dimensionless quantities simplifies the calculation and construction of relationships between the parameters in an explicit form. Based on the obtained relations, recommendations to design of various electric devices with levitation elements are developed.
Keywords: electric device, levitation element, magnetic conductor, excitement winding, indicator of parameters, thermal stability, cross-sectional area, optimum size
