Electromechanical Energy Conversion

Since the beginning of the first industrial revolution, electromechanical energy conversion (EMEC) devices have been providing the highest acceleration for industry. EMEC devices are the driving force for maintaining a stable and continuous development for industry. The EMEC process is the result of the required energy storage (ES) for the daily needs of society. The technologies associated with the concept of ES, renewable energy (RE) sources, and electromechanical (or any kind) energy conversion systems are all interrelated. In terms of the double-conversion chain, which is described as "electricity-storable intermediary energy-electricity," the storable intermediary energy is established by sophisticated conversion systems between the energy sources and the electricity. In this analysis, in order to have a complete understanding of energy conversion associated with the energy sources, the conversion technologies are reviewed in terms of the operation principles of the conversion devices from transducers to rotating machines. The main focus is on the description of the energy sources, especially in RE, ES, and associated technologies. Lastly the EMEC technologies are discussed under the energy concept and an evaluation is provided in terms of the existing and emerging technologies.
