Decrypting the heart of the car: Understanding the car motor

The automobile motor is the core part of modern transportation, which is indispensable as the heart of the human body. It is not only a simple electric drive unit, but also one of the most sophisticated and complex links in the entire power transmission system. Compared with traditional fuel engines, the new generation of high-efficiency motors used in electric vehicles have the characteristics of small size and light weight, and can output greater torque in a lower speed range, thereby greatly improving driving efficiency.

With the advancement of technology, more and more traditional car companies have begun to set foot in the electric vehicle market, and the speed of research and development of new models is also accelerating. For example, the Tesla Model S series is equipped with two high-performance three-phase asynchronous motors that work independently, which far exceeds competitors of the same level in terms of acceleration performance; the BMW i3 uses a more compact integrated permanent magnet synchronous motor design. It saves space and reduces noise pollution. These examples demonstrate the transformative potential of advanced motor technology for the automotive industry.

The technological revolution of the source of power

Looking back over the past few decades, automotive motors have undergone tremendous changes. From the initial simple construction to the current highly integrated product form, each iteration of the update marks a leap forward in this field. In particular, some key technological breakthroughs in recent years have enabled the new generation of motors not only to have higher energy conversion efficiency, but also to operate with low energy consumption and provide a smooth power output experience.

• Permanent magnet synchronous motor (PMSM): Due to the built-in permanent magnetic field material, this type of motor can generate a strong electromagnetic field under lower current conditions, thereby achieving a better power density ratio.
• AC induction motor (ACIM): By changing the winding voltage frequency to control the rotating magnetic field change law, suitable for applications that require frequent start and stop operations.
• Brushless DC motor (BLDC): After removing the traditional carbon brush structure, the mechanical friction loss is almost non-existent, so it can work stably for a long time without being damaged.

Choose the type of car motor that suits you

in the face of a dazzling array of options on the market, how should you choose the right motor for your car? the answer is actually very simple-that is, according to the specific use of the scene to make a comprehensive consideration. For most urban office workers, when the daily commuting distance is short and the traffic situation is congested, a small and efficient single front motor is enough to meet the demand. For those who pursue extreme driving control pleasure or often travel long distances, it is recommend to be equipped with high-performance vehicles with front and rear dual-drive or even four wheels with independent motor configurations.

In addition, we also need to consider the cost-effective factors within the scope of personal budget and the brand after-sales service network coverage and other conditions. In short, as long as you make a wise decision after clarifying your actual situation and combining the opinions of professionals, I believe that every car owner can find the ideal product that is most suitable for your car!

Important components not to be ignored

A complete electric drive system is not only a combination of several pieces of hardware, but also involves many seemingly insignificant but extremely important auxiliary components. For example, the controller is used to adjust the power supply to adapt to different load requirements; The inverter converts a fixed input into an adjustable output form for downstream equipment. There are also various sensors responsible for collecting real-time data and feeding back to the central processing unit so as to adjust the setting values of various parameters in time.

It is worth noting that although the parts in some special positions are usually not conspicuous, they are the key to ensure the normal operation of the whole. For example, the heat sink is one of them. Good cooling effect can not only prevent overheating and protect the internal circuit from damage, but also help to extend the service life and make every trip more reliable.

Installation, maintenance and troubleshooting

in order to put the new car into normal use as soon as possible, when receiving the newly purchased motor and related accessories for the first time, the correct connection test procedure must be completed according to the instructions in the manual. The next step is to enter the daily maintenance stage ~ remember to arrange an all-round inspection and cleaning task every certain mileage, especially to clean up dust and sundries at the vent so as not to affect the smooth flow of the air duct and cause problems such as decreased work efficiency ~

of course, it is inevitable that we will encounter some minor troubles occasionally. at this time, we need to master some basic maintenance knowledge and skills! For example, when it is found that the instrument panel displays abnormal alarm lights, don't panic, calm down and carefully check whether there is poor contact and looseness before taking corresponding measures. If you do encounter a situation that is difficult to repair by yourself, don't worry, you can contact the official after-sales service center to seek professional technical support to help solve the problem.

The Road to the Future: Opportunities and Challenges in the Era of Intelligent Networking

Looking forward to the future from the starting point of the new era, the new energy automobile industry is ushering in an unprecedented
