Coreless Generators
Sky Electronics’ coreless generator is powerful and environmentally friendly.
Generators
Natural energy, consisting of wind, water, and solar power, is attracting worldwide attention as an environmentally friendly energy source. Since no CO2 is emitted during power generation, it helps preventing global warming. It is also considered a sustainable energy source because there is no possibility of depletion.

By taking advantage of our position as a coil manufacturer, we can customize our coils to meet your needs such as using thinner wire diameters for higher voltage at lower RPM etc..
We develop special generators by utilizing the winding technology we have cultivated over many years. We will make it as close as possible to the customer’s requirements.
