Chapter 220 High Efficiency Motor

Just start making cars? Lu Zixin felt that it was unrealistic. To turn technology into reality, he needed to overcome many difficulties, especially what he obtained was a technology that the current motor vehicle industry has not yet mastered, and the difficulty factor has doubled!

Before making a car, you should build a relatively simple motor vehicle for technology and capital accumulation, such as building a company, a factory, and establishing a complete upstream supply chain and downstream sales chain.

"Electric vehicles seem to be the best choice at the moment?" Lu Zixin thought about whether electric vehicles are the best way to start.

Electric vehicles are broadly defined as all electric vehicles, but what Lu Zixin thought was the two-wheeled electric vehicles that everyone rides in daily life, commonly known as small electric donkeys.

The structure of the small electric donkey is much simpler than that of the four-wheeled vehicle, and the manufacturing is relatively simple, and the industrial requirements are lower.

Moreover, even if it is an electric car, it does not mean that there is no black technology!

Lu Zixin asked RI-8901 to search in the "Simple Mechanical Structure Atlas", and soon found several black technologies that he could try to develop.

The first is the multi-core control of the intelligent and efficient motor, the motor, that is, the engine of the electric vehicle.

It is made of high-strength magnetic steel and added with an intelligent control chip, which can be activated instantly by electrical or wireless signals.

This kind of motor can reduce the current loss and improve the power. Some ordinary electric vehicles can run on flat roads, but once they climb a slope with a relatively high gradient, it is very difficult, and even the load must be reduced.

But for the multi-core control intelligent and efficient motor, these are all small problems. The power it generates can even make the user feel the push back of the car's acceleration!

Another is the electromagnetic braking system. Electromagnetic braking is an existing technology, but the application level is still only on large-scale mechanical equipment, such as mine electric drills, roller coasters and the like.

Traditional friction brakes will have instability, such as slipping in rainy days and snowy days, resulting in poor braking effect.

The electromagnetic brake relies on the interaction force between the magnetic poles to realize the brake. When the metal sheet cuts the magnetic field line, an eddy current will be generated inside the metal, which will generate a magnetic field to resist the movement. In fact, the device of the magnetic brake is not in direct contact with the car body! Therefore, it will not be affected by external road conditions and weather.

This electromagnetic braking device often requires the cooperation of fixed magnetic poles, so it is rarely used in general motor vehicles. Even if some cars are used, they are only assisted by electromagnetic braking, mainly relying on friction braking.

In the mechanical map given by Optimus Prime, this technical obstacle has been overcome, and the electromagnetic braking device can be installed on moving machinery, not only vehicles, but also other sports machinery.

In addition, there are also some designs, such as the body, transmission, etc., if carefully built, the electric vehicle produced can even surpass the gasoline motorcycle in terms of speed and other performance!

Of course, the pursuit of speed is a high-end racing car. Lu Zixin has not considered it for the time being. What he wants first is a family electric car. Only when the manufactured products have a market and become profitable can a virtuous circle be formed and money will continue to be invested in research and development.

Regardless of how much money Hongxin Company makes, Lu Zixin almost threw two-thirds of it into R&D. Combined, the various subsidiaries of Hongxin Group have five R&D centers under construction and more than 100 laboratories, and every new project is established, this number will increase.

The investment in research and development, ranging from tens of millions to as many as one billion, has been burning money!

This is also something that can't be helped, and the research of Red Letter is all "breakthrough" technical fields. For other enterprises, even state support can't come up with so much money to invest.

In addition to mechanical equipment and structure, Lu Zixin believes that improvements are needed, and modifications are also required in the direction of intelligence.

He recruited several professionals to discuss with them.

There were three people in total, one of whom was Professor Cheng Mu of Mechanical Power and Engineering from Jiangda University, who was invited by Lu Zixin.

One is Jiang Xunmei, a woman in her 40s and a little fat. She is a senior executive of a car brand. She has resigned and has rich experience.

Another is Han Jia from Hongxin Software Development Co., Ltd. He is also very good at intelligent systems.

Lu Zixin talked about his idea, Cheng Mu thought for a while, and was the first to express his opinion.

Compared with other professors, Cheng Mu is much younger, only in his early thirties. He said: "Multi-core control of intelligent and efficient motors has several problems. It uses high-strength magnetic steel materials and super-hard permanent magnet alloys, which are in It's a bit difficult to manufacture."

"Increasing the horsepower of the motor requires a strong current, so the requirements for the battery will also increase. If the general electric vehicle battery supports this kind of motor, the power reserve will be insufficient, resulting in the continuous increase and decrease of the battery life."

...

"There is also an electromagnetic braking device. There is no problem with the auxiliary electromagnetic braking device. However, if all electromagnetic braking devices are used, a larger braking force is required, which will lead to the overheating of the metal sheet..."

Lu Zixin nodded, his smart glasses recorded Professor Cheng Mu's words, and Lu Zixin would solve these problems in detail later.

Jiang Xunmei said: "Mr. Lu, if your lithium-air battery can achieve the theoretical effect, I think it will not lack the market based on this alone."

"Then if what you said just now is done, what do you expect the market to be like?" Lu Zixin asked.

"Do it all?" Jiang Xunmei said, "If it can be done, it will definitely be second to none in terms of performance. But the current electric vehicle brands, such as Emma, ​​Yadi, Luyuan, etc. in China, have occupied half of the country, and their products The performance is not bad. There are also some foreign brands, and the competitiveness is not bad.”

"In terms of manufacturing costs, they are definitely cheaper and more competitive. So I estimate that the market sales will not exceed them, but it will not be bad."

Although the theoretical electric vehicle proposed by Lu Zixin sounds good, as a professional, she knows that the manufacturing cost has at least doubled!

As most consumers, would they be willing to pay more than double the price of an electric car? There are only a few!

"We, Hongxin, have always only made the most advanced products!" Lu Zixin said, "so we have to improve its competitiveness so that electric vehicles can also be included in smart products."

Han Jia said in surprise: "Mr. Lu, do we want to do driverless electric vehicles first?"

"Unmanned driving is a separate project. It's not urgent to do it now," Lu Zixin said. "Didn't we just make a smart home system? My idea is to include our electric vehicles into the smart management system first. , make it a smart product, not an ordinary electric car."
