Abstract. For design of electromagnetic devices with levitation elements (EU with LE) the generalized indicators are established: values of current in the modes of current and efforts, carrying power, the working course, electromagnetic pressure, time of start-off, electromagnetic rigidity and loading capacity. Analytical expressions for the generalized indicators which contain dimensionless quantities are derived to simplify calculations of the proposed indicators and create interrelations between the parameters in explicit form. Recommendations to design of various EU with LE are developed.
Keywords: electromagnetic devices, levitation elements, generalized indicators for design, levitation coordinate, working course, loading capacity, carrying power, electromagnetic rigidity, electromagnetic pressure, thermal firmness start-off time, amplitude of fluctuations
