It is normal for the generator to generate heat during operation.
The automobile generator is the main source of power for the car. Its function is to power all electrical equipment (except the starter) and to charge the battery when the engine is running normally.
Based on the three-phase stator winding of an ordinary alternator, the number of winding turns is increased and the terminals are taken out, and a set of three-phase rectifier bridge is added. At low speed, the original winding and the additional winding are output in series, while at higher speed, only the original three-phase winding is output.
Detailed information:
1. Principle of gasoline generator:
The gasoline engine drives the generator to operate, converting gasoline energy into electrical energyeu.
In the cylinder of the gasoline engine, the mixed gas 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, thereby 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.
2. Precautions for use:
① Frequently clean the scale and dust on the appearance of the generator and keep it cleanand well ventilated.
② Frequently check the tightening conditions of the generator-related fasteners and tighten the screws in time.
③The tension of the drive belt should be appropriate. If it is too loose, it will slip easily and result in insufficient power production; if it is too tight, it will easily damage the belt and generator bearings.
④When installing the battery, be careful not to install it incorrectly. Usually, install the positive wire first and not the ground wire, otherwise the diode will burn out easily.
⑤ When using an integrated circuit regulator, the ignition switch should be turned off immediately when the engine is not running.
⑥ It is never allowed to use the “scraping” method to test whether to produce electricity.

Whyoi is the car generator hot to the touch
Yes, as long as the battery has power it can start. The car starts by relying on the starter to drive the engine, then the engine drives the generator to store electricity.
How to determine if there is a problem with the car generator:
After starting the car engine, use a voltmeter to measure the voltage on the + pole - drums. Generally, the normal range voltage will be (heating) (idle) around 12.3~14.3V, which is normal.
2. After starting the car engine, use a clamp voltmeter. Remove the clamps from the generator output wire (specifically, the wire going from the generator to the battery, usually shown in red or blue). Generally, the normal voltage range will be around 12.3~14.3V (warm-up) (idle). . normal. If the above voltage range appears, it may be cconsidered normal. If it exceeds, it can basically be considered abnormal. If the voltage exceeds 14.3 V too much, it is considered that there is a problem with the voltage stabilizing component. the voltage drops too much beyond 12.3v. If yes?, it is considered that there is a problem with the rectifier component, the carbon brush or the rotor stator. The components mentioned above can all be replaced independently. It is recommended to start with the simplest and cheapest ones.
Serious lack of coolant.
If the car owner does not check, uncover and add coolant in time, it will easily cause the engine to overheat. According to the car owner: the engine will be very hot after driving. some time, and it should not stop. This is a lack of coolant problem. He is very probprobably due to a leak in the water tank pipe and a serious lack of coolant.
Precautions for car generators
A belt that is too loose on the generator will easily slip, causing the generator to undercharge the battery, resulting in power loss of the battery and, in serious cases, the battery may lose power. The amount of energy cannot start the engine. Therefore, the tightness of the generator belt should be checked and replaced from time to time. The replacement cycle of belts is about 60,000 to 80,000 kilometers, and a small number of belts can be replaced between 80,000 and 100,000 kilometers.
If the battery status observation hole is always black, it means that the battery power has been insufficient for a long time. It is likely that there is a problem with the generator and il could not load efficiently. battery. At this point, the generator should be checked to avoid complete breakdown. It is normal for the battery viewing hole to appear green.
