<1> Overview of generator
A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. Converted to electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. the
There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other, so as to generate electromagnetic power and achieve the purpose of energy conversion.
<2> The classification of generators can be summarized as follows:
Generator points: DC generator and AC generator
Alternator points: synchronous generator and asynchronous generator (rarely used)
Alternators can also be divided into single-phase generators and three-phase generators. the
<3> Generator structure and working principle
Generators are usually composed of stators, rotors, end covers, bearings and other components. the
The stator is composed of stator core, wire wrap winding, frame and other structural parts that fix these parts. the
The rotor is composed of rotor core (or magnetic pole, magnetic yoke) winding, guard ring, center ring, slip ring, fan and shaft and other components. the
The stator and the rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and do the movement of cutting the magnetic force line, thereby generating an induced potential, which is drawn out through the terminal and connected to the circuit to generate a current.
Gasoline generator principle
The gasoline engine drives the generator, which converts the energy of gasoline into electricity. the
In the gasoline engine cylinder, the mixed gas burns violently, and the volume expands rapidly, pushing the piston down to do work. The cylinders perform work in a certain order, and the thrust acting on the piston becomes the power to drive the crankshaft through the connecting rod, thereby driving the crankshaft to rotate. Install the brushless synchronous alternator coaxially with the crankshaft of the gasoline engine, and the rotation of the gasoline engine can be used to drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator will output induced electromotive force, and the current can be generated through the closed load circuit.
