Buy a small 12V battery to magnetize the generator and remove it after generating electricity.
A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electric machines to convert the energy generated by water flow, air. flow, fuel combustion or atomic nuclear fission in Mechanical energy is transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
Generators come in many forms, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is as follows: utiliser suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction between them to generate electromagnetic energy and achieve the goal of energy conversion.
Diesel generator
The diesel engine drives the generator to convert diesel energy into electrical energy. In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the temperature increases rapidly, reaching ignition. point of diesel fuel. Diesel ignites, the gas mixture burns violently, rapidly expands in volume and pushes the piston down, which is called "work".
Gasoline generator
The gasoline engine drives the generator to convert gasoline energy into electrical energy. In thecylinder of a gasoline engine, the gas mixture burns violently, expands rapidly in volume, and pushes the piston down to do work.
Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thus driving the engine. crankshaft to rotate. By installing the brushless synchronous alternator coaxially to the crankshaft of the electric machine, the rotation of the electric machine can be used to drive the generator rotor. Using the principle of "electromagnetic induction", the generator will produce induced electromotive force. and a current can be generated through the closed charging loop.
Normal power generated by a 12V generator is between 12.6 volts and 14.5 volts. The normal power output of a 12 volt generators should be between 12.6 volts and 14.5 volts, which is the safe floating voltage value of the 12V battery. In this voltage range, the generator can effectively charge the battery and maintain a stable power supply . To calculate the power output of a 12V generator, you can use Ohm's law, that is, voltage times current equals power. For example, the current of a 12V generator is 120A, its power output can then be calculated by the formula P. is equal to U divided by I. The result is 1440W means this generator can put out 1440 joules energy per hour. 12 volt generator is a common power generation equipment, mainly used to power vehicles, ships, etc. Its function is to power all electrical equipment (except the starter) and the battery when the engine is running normally (above idle speedi).
