Vertical Axis turbines are suitable for grid connection, stand alone through a hybrid system, battery charging, and water heating. Installations can be found in many public spaces in countries around the world. Those kind of turbines are extremely silent, safe and reliable, with high efficiency and low maintenance costs. The turbines are capable of resisting strong and unstable winds.
The turbines are able to start operating at low wind speed and generate energy independently from its direction. They are designed and engineered for series production, and the small amount of mechanical parts significantly reduces the maintenance costs offering clients a product easy to assemble.
With vertical-axis wind turbines, electricity is generated through a synchronous direct drive three-phase permanent magnet generator. Magnets are attached to the rotor while the stator holds the windings. Such configuration increases the generator performance simultaneously reducing noise and wear and assuring great efficiency in power production.
The absence of mechanical transmissions and the stiffness of parts allow the turbines to operate silently. The phonometric analyses confirm that the noise level is irrelevant.
The vertical-axis configuration allows the turbines to take air fluxes coming from every direction requiring no repositioning aid as horizontal-axis turbines do.
