Outline of Final Research Achievements |
The development of a power generation system using renewable energy is necessary for global warming countermeasure. The purpose of this research is to develop a power generating system with high power, high efficiency and high reliability, which is used in micro hydro power and/or wind power system. Moreover, it is to save the amount of permanent magnet, because it is expensive and has bias in the producing country. In order to develop a novel power generation system, we have developed a method for designing the rotor structure from the empty space, and have manufactured the designed one. The developed generator has 46 % higher output power and 2% higher efficiency than those of a commercialized one. Moreover, this research has clarified the method for the diagnosis of magnet decrease due to high temperature, and has developed the system with high reliability.
