Generalized mathematical model of EMS (a homogeneous body or a multi-weight estimated heat balance diagram) for various operation conditions of a facility allows to identify diagnostic indicators (criteria) for taking specific measures to stabilize its operation. Increasing efficiency of the facility thermal state monitoring can be achieved using noncontact measuring instruments to determine temperature distribution over the facility surface. Temperature distribution over an EMS facility surface enables concluding on maintenance necessity. For effective application of noncontact thermal-imaging equipment for diagnostics of EMS on the basis of the provisions presented in the paper, training program for specialists in thermometering of industrial facilities has been developed.</p></abstract><trans-abstract xml:lang="ru"><p>В работе рассмотрены вопросы контроля теплового состояния объектов промышленной группы производственных механизмов на основе обобщенного подхода к пониманию причин и целей диагностирования электромеханических систем (ЭМС) по текущим значениям температуры. Обобщенная математическая модель ЭМС (однородного тела или многомассовой расчетной тепловой схемы замещения) для различных режимов работы объекта позволяет обозначить диагностические признаки (критерии) для принятия конкретных мер по стабилизации его работы. Повышение эффективности контроля теплового состояния объектов можно достичь при использовании приборов бесконтактного измерения распределения температур по всей поверхности объекта. По виду распределения температур по поверхности объектов ЭМС можно сделать вывод о необходимости проведения ремонтных работ. Для эффективного использования бесконтактной тепловизионной техники для диагностики ЭМС на основе изложенных в статье положений разработана программа подготовки специалистов по термометрированию промышленных объектов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тепловой контроль</kwd><kwd>электромеханическая система</kwd><kwd>тепловая расчетная масса</kwd><kwd>распределение температур</kwd><kwd>диагностический признак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermal monitoring</kwd><kwd>electromechanical system</kwd><kwd>thermal estimated weight</kwd><kwd>temperature distribution</kwd><kwd>diagnostic indicator</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Baranski M., Polak A.
