Applications/Examples of results

▶Wind Power Generation The biggest advantage of wind power generation, unlike solar power generation, is that it can generate electricity 24 hours a day even in bad weather (cloudy/rainy conditions) and at night when the wind blows. Additionally, offshore wind power generation, which can be installed not only on land but also at sea, has improved issues related to noise. In such circumstances, we have developed a coreless motor wind power generator that is highly efficient and low in noise. ▶Hydropower and Wave Power Generation The greatest advantage of hydropower generation is that, unlike solar and wind power generation, it is not significantly affected by weather conditions. In Japan, there are many irrigation channels, and utilizing their energy can yield a very large amount of energy. Coreless motor hydropower generation is widely used in recovery projects from earthquake disasters and other applications. ▶Other Power Generation Power generation methods such as engine generation and gas turbine generation can produce electricity without being affected by environmental changes. Coreless motor generators contribute to the miniaturization and lightweight design of systems due to their light weight and small size.
