One of the major problems of improving the competitiveness of products in the global market is to reduce the energy component in the structure of its cost. The cost of electricity consumed electromechanical system during the lifetime (life cycle), significantly exceeds the cost of equipment and maintenance costs. Operating electromechanical systems that are in poor condition, resulting in increased financial expenses due to the growth of power consumption. The main reason for the low efficiency of electromechanical systems and accident management is ignoring the impact of money supply voltage and load profile, lack of information on the technical condition, lack of effective continuous motor protection, failure detection and elimination of defects in the equipment, insufficient use, faulty repairs, etc. One of the obstacles to wider introduction of energy saving in life is that control rational use of energy is not applied to a specific customer process - electromechanical system. Energy aperiodically it is estimated, for example, during the energy audit. A promising approach is the implementation methodology for energy management of a permanent energy efficiency of electromechanical systems for rapid response to worsening energy situation and violation of a regime. The authors proposed solution is to assess the real-time energy and technical condition of electromechanical systems to identify inefficient modes of operation and make informed decisions about further exploitation. The mathematical apparatus combines energy efficiency management methods analyzing instantaneous values of current and voltage output, ambient temperature and allows to determine energy efficiency and predict remaining life of electromechanical systems, by spectral analysis of current, which enables early detection of damage motor and associated mechanism. By authors firmware management energy efficiency of electromechanical systems - models, methods, algorithms, programs and scheme-technical decisions take into account the quality of the supply voltage, load and temperature mode environment.
