An automobile generator is an integrated alternator. Its working principle is:
Most automobile generators are silicon rectifier generators, which are mainly composed of a three-phase alternator and a silicon diode rectifier. .
Working principle: When direct current flows through the rotor winding, the rotor claw poles establish a magnetic field. When the rotor rotates, the magnetic lines of the magnetic pole cut the stator winding and the induced alternating electromotive force. the armature coil is reversed by switching. The device cooperates with the switching effect of the brush, so that it becomes a DC electromotive force when exited from the end of the brush.
As long as the generator is normal and undamaged, the rotor can spin to produce electricity, but the electricity generated is not stored in the battery! The lines of force mmagnetic in the generator are generated by magnets!
The automobile generator is the main source of power for the car. Its function is to power all electrical equipment (except the starter) when the engine is running normally (above idle speed) and to charge the battery. at the same time.
Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines to convert water flow, air flow. , combustion of fuel or atomic nuclei. The energy generated by fission is converted into mechanical energy and transmitted to the generator, which is then converted into electricity.
The difference between generators mainly lies in two points:
The difference in electricity production methods
The difference in the principle and structure of generator power generation
The generator is as follows:
The main shaft is equipped with a rotor slip ring, a stator slip ring, a stator, a rotor. The stator track, direction change wheel, rotor track and pulley, etc. are fixed by the stator and rotor brushes in the internal cavity. of the housing to produce electrical energy. When the main shaft rotates, it drives the rotor track clockwise and drives the rotation of the direction change wheel. The stator track connected to the stator and the stator slip ring is driven by friction to rotate counterclockwise, so that the stator and rotor. in the generator runs in opposite directions to achieve The purpose of increasing the speed is to improve the production efficiency of'electricity. It features simple structure, low manufacturing cost and convenient operation and maintenance.
