Simple generator : AC Electric generator working model using Dc motor and magnet - 11 W bulb test - History project : https://electricgeneratorproject.blog...

The video presents an experimental AC generator composed of : a DC motor, a neodymium sphere magnet fixed on the motor shaft between the magnetic poles, two coils air core and a 3,7 V li-ion battery. The 230 V bulb 11 W is connected to the coil output ( AC output).
The generator behaves like a mechanical inverter (DC to AC ) , the voltage increases, the amperage decreases. The voltage is high enough to light the halogen bulb 230 V 11 W.

NOTE :

The bulb does not light at full intensity.

What is happening ?

Energy is transferred from the battery to the coil output through mechanical coupling.

rotor : 2 poles (N and S ) neodymium sphere
stator : 2 coils air core
input : DC, Li-ion 3.7V 2200 mAh 18650 Lithium-Ion Cell (Rechargeable)
Output : AC
Bulb : 11 W bulb 6400 k 230 V 50 Hz
Class : mechanical inverter

About generators :

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks.


Why free energy is not possible?

Free energy machines do not work. No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal. The law of mass-energy conservation states that mass-energy can never be created or destroyed.

According to the first law of thermodynamics, the total amount of energy in the universe is constant.
Energy can be transferred from place to place or transformed into different forms, but it cannot be created or destroyed.
Living organisms have evolved to obtain energy from their surroundings in forms that they can transfer or transform into usable energy to do work.

How much electricity does a generator produce?

As a standard rule, companies rate the generator output in Watts (W) or Kilowatts (kW). The accepted formula is Watts = Volts X Amps. Therefore, when you purchase a 2 kW generator delivering 230 Volts, it can give you an output of 8.69 amps

Why is the efficiency of a generator less than 100%?

Let’s look a simplest generator, a shaft-driven one. First losses you have in creating the shaft power, than you still have a shaft rotating on bearings. There is friction in these bearings, it can be minimized but it cannot be eliminated because two moving surfaces contacting each other always have a frictional component. We have a moving conductor in a magnetic field, producing power (voltage * current). However, the current in the windings experiences resistance, because electrons moving in a conductor (the wires) bang into stationary atoms and experience a loss of energy, manifested as heat since that energy is transferred to the stationary atoms.

Question : " What about the You Tube videos with the free energy content which are tones, are they real ? "
Answer : The videos which are presenting free energy devices on You Tube are scams. YouTube team have to reviewed their content which violates their spam, deceptive practices and scams policy. All free energy You Tube content has to be eliminated as soon as possible.


probably some of you will say " ok, S.T. , you light domestic bulb 11 W, why don't you try to light a 75 W halogen domestic bulb :) ?

Yes. It is possible
