Vertical wind turbine is an extremely durable and efficient wind turbine of the latest generation. Whirly1.0 wind turbine has a technological and highly efficient vertical blade design and a permanent magnet generator having strong N42 neodymium magnets with steel slots inside. In case the wind speed is over 3 m/s, the turbine will be rotating freely by exceeding this holding torqueThe maintenance-free sliding contact (slip ring) guarantees a good current flow and thereby no twisting of the cable in the pole. Whirly1.0 wind turbine generates AC Electricity to charge DC batteries or to feed an on-grid inverter to be connected to Grid.
