To develop a diagnostic complex meeting the criteria and requirements for carrying out accelerated reliability test and realizing the basic modes of electric machines operation and performance of the posed problems necessary in the process of such test. Methodology. To determine and forecast the indices of electric machines reliability in accordance with the statistic data of repair plants we have conditionally divided them into structural parts that are most likely to fail. We have preliminarily assessed the state of each of these parts, which includes revelation of faults and deviations of technical and geometric parameters. We have determined the analyzed electric machine controlled parameters used for assessment of quantitative characteristics of reliability of these parts and electric machines on the whole. Results. As a result of the research, we have substantiated the structure of a computerized complex for electric machines reliability test. It allows us to change thermal and vibration actions without violation of the physics of the processes of aging and wearing of the basic structural parts and elements material. The above mentioned makes it possible to considerably reduce time spent on carrying out electric machines reliability tests and improve trustworthiness of the data obtained as a result of their performance. Originality. A special feature of determination of the controlled parameters consists in removal of vibration components in the idle mode and after disconnection of the analyzed electric machine from the power supply with the aim of singling out the vibration electromagnetic component, fixing the degree of sparking and bend of the shaft by means of phototechnique and local determination of structural parts temperature provided by corresponding location of thermal sensors. Practical value. We have offered a scheme of location of thermal and vibration sensors, which allows improvement of parameters measuring accuracy due to determination of the spatial vector of vibration and local temperatures of structural parts. Разработана структура диагностического комплекса для испытаний электрических машин на надежность, обеспечивающего необходимые режимы роботы при варьировании температурных и вибрационных факторов. Предложенный комплекс является унифицированным и позволяет учитывать действительное состояние исследуемой машины, а режимы испытаний не нарушают физики процессов старения и износа конструктивных узлов и материалов. Розроблено структуру діагностичного комплексу для випробувань електричних машин на надійність, що забезпечує необхідні режими роботи при варіюванні температурних і вібраційних факторів. Запропонований комплекс є уніфікованим та дозволяє враховувати дійсний стан досліджуваної машини, а режими випробувань не порушують фізику процесів старіння і зношування конструктивних вузлів та матеріалів.
