Outline of Final Research Achievements

This study presents the mini hydro-electric power generator having double rotors. The micro-hydroelectric power generator requires to be a robust and a stable output. The generator has the reverse rotation twin rotor with the test apparatus. In first step the study is carried out to make the twin water wheel prototype test apparatus using a small size facility. The experiment has been varied the basic characteristics of a generator with twin water wheel prototype test apparatus using a small size facility. Moreover the study investigates the external load characteristics of a synchronous generator with axially arranged excitation and permanent magnet cores, using experiments and analyses.
