Manual for wind turbine construction

This manual describes how to build a 'permanent magnet generator' (PMG). We can also call it an 'alternator', because it generates alternating current (AC). It will not generate 'mains voltage' or 'utility power' AC. It generates low voltage, 'three phase'AC, and then changes it into 'direct current' (DC) for charging a 12 volt battery.Click Here

Wind speed average in Indonesia

Indonesia has wind speed average (V mean ) one that inferior of state that use wind power conversion system as Finland, United States of America, and another states. Regions at Indonesian generally has v mean between 3-6 m / s, really in contrast to ranging Europe state within 9-12 m / s. Wind characteristic at Indonesian evoke problem if technology that applies to be designed follow European state wind characteristics.

On the NASA's Image can be seen that region has wind speed average greatest is Nusa South East, 5.5-6.6 m/s. Meanwhile island outgrows at Indonesia as Sumatra, Borneo, Java, Sulawesi and Papua just have wind speed average between 2.7-4.5 m/s.
