Working diagram of generator

Working diagram of synchronous generator Electricity is one of the main energy sources in modern society.

The stator and rotor of the generator are connected and assembled by the bearing and end cover, so that the rotor can rotate in the stator and make the movement of cutting the magnetic line, thus generating an induced potential, which is led out through the terminal and connected to the loop, and an electric current is generated.

The control diagram is as follows: Principle: The diesel engine drives the generator to run and converts the energy of diesel into electricity.In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector. Under the upward squeezing of the piston, the volume shrinks and the temperature rises rapidly, reaching the ignition point of diesel.

Automotive circuit schematic diagram (understand the basic composition and working principle of the vehicle electrical system)

1, composed of storage batteries, generators, regulators, charging status indicators, open The electrical system composed of off and wires is called the power supply system (referred to as the power supply system), as shown in the figure. Composition diagram of the power supply system. The working process of the automobile power supply system. The battery and generator in the power supply system work in parallel.

2. The generator is an automobile electricalAn important part of the system, it is mainly responsible for providing electricity for the vehicle and ensuring the normal operation of various equipment of the vehicle. By turning the generator rotor, the generator generates electromagnetic induction and converts mechanical energy into electrical energy.

3. The connection point between the generator and the storage battery and between the subsystem should be kept in place as much as possible, and the connection of the fuse, switch and instrument should be basically consistent with the original figure.

4. Local circuit diagram: In order to clarify the internal structure of automobile electrical appliances and the interconnection between various components, and to understand the working principle of a certain part of the circuit, a part of the circuit that needs to be studied is often extracted from the circuit diagram of the whole vehicle, referring to other detailed information, and if necessary, according to field mapping, detection and testing Record, enlarge, draw and explain the key parts.

5. Familiar with automotive electricityThe rules of the road map are in the circuit diagram of the whole vehicle. All electrical appliances are arranged from left to right (the power supply is on the left, the electrical appliances are on the right, in the partial circuit schematic diagram, the signal input is on the left, and the signal output is on the right) and from top to bottom (the fire wire is above, the ground wire is below), and the circuits of all electrical systems are drawn together as much as possible.

6. Mechanical transmission system The mechanical transmission system has a simple structure and reliable operation, which is widely used in all kinds of automobiles. Its basic composition and working principle: the power of the engine is transmitted to the rear drive wheel through the clutch transmission universal joint transmission shaft main reducer differential half-shaft 6.

The working principle of automobile generator

The engine drags the DC-excited synchronous generator rotor, rotates at speed n, and the three-phase stator winds the resistance to induce the AC potential.If the stator winding resistor is connected to the electric load, the motor has AC power output, and the alternating current is converted into direct current from the output terminal through the rectifier bridge inside the generator.

The working principle of the generator The stator and rotor diagram of the generator (1) The rotor coil must be energized to generate a magnetic field: the rotor coil is powered through the F and E junction columns, and the rotor coil is energized to produce a magnetic field. ( 2) The engine work drives the rotor rotation: that is, the magnetic field rotates, the stator coil cuts the magnetic line and generates alternating current in the stator coil.

The working principle of the automobile alternator is to connect and assemble the stator and rotor of the generator by the bearing and the end cover, so that the rotor can rotate in the stator and make the movement of cutting the magnetic line, thus generating an induced electric potential, which is led out through the terminal and connected to the loop, and an electric current is generated.
