The paper proposes an approach to diagnostics of asynchronous electric motors based on the application of hierarchical functional models that are built using the IDEF0 methodology for integrated consideration of the influence of electric power quality indicators. A brief analysis of the problems of diagnostics for asynchronous electric motors is given, which justifies the relevance of developing new methods and models of diagnostics. A distinctive feature of the proposed hierarchical functional diagnostic models of asynchronous electric motors is a formalized representation of the necessary process functions using the IDEF0 methodology. This allows one to identify the main data flows in the diagnosis process, extract knowledge about the process, and reveal the cause-and-effect relationships of failures of asynchronous electric motors, complementing traditional methods of technical diagnostics by analyzing compliance with regulatory requirements concerning the electrical energy quality. A brief description of the developed methods, models and algorithms, as well as the results of experimental research, efficiency analysis of the proposed methodology is provided.
