Iran has been known for Her vertical shaft ancient wooden windmills. In recent
years, the wind turbines became subject of interest after some thousand
years. The first modern Iranian designed and manufactured wind turbine with
a nominal output of 600 kW has been designed and manufactured by Inst. A.
Ayvazian & Associates. The wind turbine KAMI 600 is stall regulated and has its
own special design gearbox with direct connection of the rotor hub on input
shaft. The turbine is designed according to relevant rules and regulations such
as GL, IEC etc. and it is successfully in operation since commissioning. In order
to design and manufacture the KAMI 600 wind-turbine, all the know-how
necessary to accomplish the task has been developed by the designers in Iran
and the turbine started running successfully from the first operation hours in a
mountainous area near Caspian Sea (North of Iran). For mass production the
wind turbine design is revised to have an output of 750 kW with some slight
changes.
