Electricity is a primary need in modern human life today. Almost all existing equipment, using electrical energy. Electricity can be obtained from various sources of energy, such as water, wind, ocean waves, solar heat, sunlight, geothermal, biogas, coal, petroleum, nuclear, and others.

Nowadays a lot of news that says about free energy, mostly in the news states, electric energy can be in without the source of energy. in fact, seeing the laws of physics regarding the law of conservation of energy, which states that energy is not created, can only be changed form, then it can be said impossible or just a product of deceit.

There is no such thing as free energy, that is, there must be a major energy source that can be converted into electrical energy. If anyone claims, they are able to create a generator without fuel / no energy (free energy), then it can be directly concluded including fraud, as it is clear against LAW or PHYSICAL LAW (ENERGY RULES LAW). One source of energy that we can use directly is wind energy or energy bayu. where for the region of Indonesia, including the category of moderate wind, meaning that most people of Indonesia can use the wind energy to be converted into electrical energy, and can be used for household purposes.

Here are some steps that we can apply to create a wind power generator that can generate power of 1000 watts. considerable power, judging by the average household electrical requirement of between 450 VA (about ~ 450 watts), 900 VA (about ~ 900 watts). It should be remembered, however, that wind energy includes unstable and unconfined energies, so ideally, the electrical energy generated ideally is fed to a battery or battery, just in the channel to the inverter (converting DC to AC) and then supplied to the load, electricity consumption of households will be ensured electrical stability.

The current discussion is only on the manufacture of electric generators only.

Necessary materials :

• 12 strong neodynum magnets (1 pole 1 face).
• 1 sheet of plywood board.
• 2 kg of resin.
• 2 pieces of bearings wire email.

Steps:

• Create a magnetic rotor house, make two rotor.

• Arrange the sequential magnetic position of North - South and so on.

• Magnetic rotor layer with resin, to make it more durable and strong.

• Wait until the resin is dry.

• Wire of stator email wire, as many as 9 pieces with each winding amount 70 turns.

• stack the email wire in the stator house, set it to 3 phase.

• phase R, connect in series 1, 4, 7 windings.
• S phase, connect in series 2, 5, 8.
• phase T, connect in series of 3, 6, 9 windings.
• connect the R, S, T winding of the star connection.

• Coat stator winding with resin.

• Install stator and rotor, against bearing.

• Output generator can be connected with diode, for charging process, (add voltage regulator circuit charging).

And we can test the experiment of the wind power machine that we have assembled earlier, good luck!
