The purpose of work is the implementation of energy-saving measures in the AC electric drives (EDF PT) when the damage of the electric motor (ED) occurs on the basis of determining their current technical condition and compensating for the effect of defects and damage on the ED operation modes and predicting its residual service life. The subject of the research is energy characteristics, diagnostic signs of defects, methods for compensating the influence of damages and defects in adjustable AC electric drives. The main scientific and practical results, their value. The developed method of identifying the parameters of the electrical complex, unlike the existing ones, is based on the compilation of energy models in the form of balance equations for the harmonic power components between the power source and the elements of the energy channel, which makes it possible to expand the number of unknown parameters of the equivalent circuit. The developed diagnostic method for asynchronous motors, unlike the existing ones, allows, based on the developed algorithm, to separate the informative frequency and spectrum of the analyzed signal, thus, it allows performing diagnostics when powered from the frequency converter.
