2. Explanation of the network
Electric drive armature: plays a key role in the process of mutual conversion of mechanical energy and electrical energy in the motor and pivot components For a generator, it is the component that generates the electromotive force, such as the rotor in a DC generator and the stator in an alternator, it is the component that generates the electromagnetic force; , like the rotor in a DC motor The armature is part of an electric motor equipped with wires. Due to the relative movement of the wires through the magnetic field between the pole pieces, a current is induced in the wires (. as in a generator) or due to magnetic induction caused by current passing through the wires, causing it to move here Rotation in a magnetic field (as in an electric motor) Armature windings are divided into two categories. : the windings of iDC armature and AC armature windings. They are used for DC motors and AC motors respectively. Motor torque = 9550 * output power/output speed, applicable to all motor torque and power calculations

How do you typically maintain a car?
How often should you perform major and minor maintenance on your car? Maintenance is usually carried out every three years or every 60,000 kilometers. It is best to complete all items in the service manual. Minor maintenance is usuallyent carried out once every six months or approximately 7,500 kilometers. There are few items, mainly replacing the oil filter.
“Minor Maintenance” generally refers to items of routine maintenance to ensure vehicle performance, primarily including oil and oil filter replacement and routine inspections. Car engines need lubrication and engine oil plays a role in lubricating, cleaning, sealing and cooling. However, as the car is driven, the base oil and additives contained in the engine oil deteriorate and become invalid. Therefore, in order to protect the engine, engine oil should be replaced regularly.
"Maintenance" is the phaseFor small maintenance. In addition to changing the oil, a third filter and spark plugs also need to be replaced. The three filters refer to the air filter,to the oil filter and the fuel filter. The filter is used to filter impurities and the third filter works to filter dust in the air, sludge in oil, carbon deposits and impurities in gasoline. Additionally, after long-distance driving, key components such as brake fluid, antifreeze, transmission oil, and timing belt need to be replaced.
Major maintenance of the car corresponds to minor maintenance: the major maintenance interval of the car is long, the mileage is long, and there are many items; minor maintenance interval is short, mileage is long; in short, and there are few articles. Major maintenance is usually carried out every three years or every 60,000 kilometers. It is best to complete all items in the service manual, such as: inspection and replacement of five oils and three waters, replacement of generator andfan belt, replacement of spark plugs. , etc. , it is a very good opportunity for us to understand the condition of the car; minor maintenance is usually carried out once every six months, or approximately 7,500 kilometers. There are few items, mainly replacing the oil filter.
Most major automotive services are performed every 20,000 to 30,000 miles or every two years. Different car brands, different driving environments and different driving habits are basically related to the time and frequency of major car maintenance. It is necessary for friends to reasonably carry out major maintenance on their car through the use of the car.
When a car has been driven for a certain number of years and kilometers, it needs major maintenance. The maintenance method of major maintenance refers to the addition of other itemson the basis of minor maintenance, that is, in addition to changing the engine oil and oil filter element, it is also necessary to check and replace the antifreeze, transmission oil, vehicle brakes. oil and steering oil.
How does vehicle maintenance stipulate the time for minor and major car maintenance?
1. Engine Oil Maintenance
If the car engine is the heart of the car, then engine oil is the blood of the car. Generally, the maintenance mileage of a car is 5,000 kilometers or six months, whichever comes first (such as Hyundai, Toyota). Some vehicles have a service mileage of 10,000 kilometers or one year, whichever comes first (such as BMW, Mercedes-Benz). ). Some vehicles have a service mileage of 15,000. It is best to refer to the service manual for the specific service mileage andyears in kilometers (like the signs).
I believe most car owners have experience doing maintenance in advance. I wonder if you were deceived by the service staff of the 4S store. You must perform maintenance in advance before the maintenance mileage is reached. reached. In fact, it's completely unnecessary. The selection of maintenance oil is mainly based on the requirements of the engine and the operating environment. There is no need to blindly search for high-quality engine oil. Just choose the right one, not the most expensive one. If the selected engine oil grade does not match, it will lead to serious consequences such as poor lubrication and oil burning.
2. Brake Fluid Maintenance
The maintenance cycle for brake fluid (brake oil) is 2 years or 40,000 kilometers. Brake fluid is the basis of the systembraking. Therefore, its requirements are relatively high. Nowadays, cars mainly use DOT4 grade brake fluid. Different grades of brake fluid cannot be mixed.
Why do you need to change the brake fluid? Because water in the air enters the brake fluid?, to lower the boiling point of the brake fluid, resulting in poor braking effect or no braking at all. Remember to change the brake fluid according to the service manual to protect yourself and others.
3. Maintenance of the water glass
The function of the water glass is to clean the windshield. Glass water is divided into winter glass water and summer glass water. There are many types of glass water on the market, so how to choose a suitable glass water?
The requirements for suitable glass water in summer are not so high. The main function ofglass water in summer is. remove the shellac. When you fill the glass with water, you can add water appropriately. In winter, glass water with a high freezing point should be selected according to the local temperature.
4. Spark Plug Maintenance
The function of the spark plug is to ignite the mixture. The service interval for spark plugs is approximately 50,000 kilometers. Spark plugs are essential for engine combustion. Why should we replace the spark plug? As the engine runs, the spark plug constantly wears out. Each ignition will wear out the electrode. Over time, the ignition energy of the spark plug will be reduced, resulting in poor engine acceleration. , misfires and other phenomena. Spark plugs need to be replaced in time and you can't be greedy to go through tens of thousands ofextra kilometers, as this may lead to unintended consequences. Especially for direct injection engines, the requirements for spark plugs are relatively high, requiring large ignition energy, prone to wear, and the replacement cycle is shortened (about 30,000 kilometers).
5. Maintenance of wiper blades
The function of wiper blades is to clean the windshield. It is recommended to replace the wiper blades depending on usage conditions. Generally, they can be replaced when the wiper effect is poor, the wiper blades are scratched or the wiper noise is loud.
6. Maintaining the air conditioning filter
The function of the air conditioning filter is to purify the air entering the car. The replacement cycle of automobile air conditioning filters is generally around 20,000 kilometers, but the replacement cyclee replacement may be shortened due to environmental problems, such as in Beijing where smog is severe. The air conditioning filter element is directly related to the air quality in the car. What are the symptoms of a dirty air conditioning filter element? When the air conditioner is turned on, you will feel that the air volume is obviously small, and there is an obvious smell in the blowing wind. If you encounter this situation, replace the filter element directly.
7. Fuel Filter Maintenance
The function of the fuel filter (gasoline filter element) is to filter fuel. There are two types of fuel filters: integrated and external. Generally, the maintenance mileage of external gasoline filter elements is about 30,000 kilometers; the maintenance mileage of internal gasoline filter elements is about 50,000 kilometers. Currently, gasoline present in some stNational service stations do not meet standards, which directly leads to a shortening of the life of fuel filters. The clogged fuel filter element prevents the engine from starting properly and the engine accelerates poorly.
8. Air Filter Maintenance
The function of the air filter is to purify the air entering the engine and prevent dust, sand and various impurities from entering and burning in the engine. Replacing the air filter elements usually occurs around 20,000 kilometers (slightly different depending on the model), which is specifically related to the driving environment of the car. A dirty, clogged air filter can lead to wasted fuel, exceeding emissions standards, engine alarms and even cylinder pulls. Disassembly and assembly of the air filter element is very simple. It's simple, you can usually clean it yourself, especially atspring when the poplar catkins fill the sky.
9. Brake pad maintenance
The maintenance of brake pads (brake pads) is judged by their use. When replacement is necessary, there will be a replacement prompt on the dashboard. In big cities like Beijing and Shanghai, vehicles are crowded and brakes are frequently used, which will shorten the brake pad replacement cycle. Generally, the loss of the front film is greater than that of the rear film. The thickness of brake pads is generally less than 3mm and it is recommended to replace them. Car owners can directly check whether they need to be replaced to avoid making a mistake.
10. Antifreeze Maintenance
The function of antifreeze is to prevent freezing and circulate heat. Antifreeze replacement cycle is 2 years or 50,000 kmres, and some cars require no lifetime replacement. The quality of antifreeze is linked to engine performance, fuel consumption and the life of each component. It is recommended to replace it according to the manufacturer's standards.
I hope it will be useful to you and I hope you will adopt it!
Routine major vehicle maintenance should be performed every 3 to 5 kilometers. Minor maintenance is determined based on the engine oil used. Different engine oil maintenance intervals are different. For example, my car uses GT engine oil. It uses PAO Category 4 base oil, and minor maintenance involves replacing it every 15,000 kilometers. It lasts three times longer than the semi-synthetic oil I used before, and the breakdown period is longer as well. I used to run 2,000 or 3,000 kilometers without feeling like thecar was not working well. I have covered 10,000 kilometers now, the power of the car is very good and it is very comfortable to drive. ∞
