Also the estimation of the overall technical state of induction motors (IM) by analyzing the frequency spectrum and the integral characteristics of the power consumed three-phase power are presented. The analysis of the current, voltage and power signals obtained with the help of the developed mathematical models of the IM operation with different degrees of development of the most common defects made it possible to reveal the regularities of the influence of existing defects on the formation of the spectral composition of power and formulate a number of coefficients for the IM diagnostics. A method has been developed to indirectly determine the energy parameters and power on the shaft of an induction motor. The obtained analytical expressions of active and reactive powers, harmonics and RMS values of variable power components allow to analyze the operation modes of electromechanical equipment in analytical form.
