Abstract  

This article covers the issues of determining the diagnostic parameters of electric motors, predicting the state of failure and its prevention, effective usage of electric equipment and increasing its reliability. It analyzes the state of failures of asynchronous motors used in our country and gives appropriate conclusions.

The main failure factors of electrical equipment were analyzed, their technical condition was assessed, and the main diagnostic parameters causing the failure state were determined, and the necessity of the parameter of the influence of the operational period on useful work coefficient was substantiated. The most common type of damage to electric motors was the burnout of the insulation or black discoloration of the coil insulation - 78.9%. In the electric motor failure case, there was three-phase burnout at 37.7%, two-phase burnout at 21.3%, and single-phase burnout at 19.9%.
