Rebirth 2008: I Can Make Money Reading

Doing research is a boring thing, even if it is an interest, it will be exhausted after a long time, so Mu Yang will go to other offices for a walk when he is free.

Walking into the secretary's office opposite, I saw Cai Xiaokun, the director of the office, and two secretaries busy, and one secretary, Wang Xiaomin, was on business trips in his hometown for a long time.

Cai Xiaokun and Mou Kun looked alike, when the HR department recommended the office director to him, this made Mu Yang pay more attention to him.

Of course, Cai Xiaokun's abilities are indeed very strong, and with Mu Yang's approval, he decided to let him be the office director for a three-month trial.

"Hello, Chairman!"

Cai Xiaokun and the two secretaries hurriedly greeted Mu Yang when they saw Mu Yang walking in.

Mu Yang glanced at Cai Xiaokun, suddenly remembered a certain Kun, standing in front of his desk, intentionally or unintentionally asked softly: "Xiaokun, can you play basketball?"

Cai Xiaokun thought that the chairman asked him about his work, but he felt a little surprised when he was asked about basketball. He thought for a while and replied: "Fortunately, after playing for seven or eight years, chairman, do you want to play basketball? Luo Zhize also played two games."

"No, just ask casually, hehe, my level is too low to play." Mu Yang smiled easily.

Luo Zhize glanced at Cai Xiaokun: "Chairman, Director Cai is very slick in basketball, and he is also very accurate in shooting three-pointers."

Cai Xiaokun said modestly: "Ronaldo won the prize, so I'm pretty average. Besides, when it comes to playing, the level doesn't matter, as long as you have fun."

"Yes, if there is no competition, the level is not important, the most important thing is entertainment." Mu Yang agreed with this statement, "You guys are busy."

Seeing the chairman leave, Cai Xiaokun couldn't figure out the meaning of what the chairman asked him.

By asking about basketball, detect his amateur activity level? See if you have the ability to organize company events?

Or through speaking skills to see how well he communicates?

Or through dialogue to see how his emotional intelligence is?

Cai Xiaokun has many guesses. He thinks that the chairman is a busy man, and he will never ask these things in vain.

But he would never have thought that the chairman really did not mean to ask him when he asked him.

Looking at Luo Zhize, he asked in a low voice, "Xiao Luo, does the chairman like to play basketball?"

"I don't know, I haven't seen him play. I heard that when I was in school, I played a dozen occasionally. The chairman asked you, maybe I suddenly became interested and wanted to ask you to play basketball together." Luo Zhize shook his head.

"Playing basketball with the chairman is not easy." Cai Xiaokun smiled wryly.

"Well, it's not easy to fight." Luo Zhize understood what he said, but he also complained, it's not easy to fight with the leader.

To play with the leader, you have to learn how to feed the ball. You can't be too serious, but you can't be too fake. The most important thing is to make the leader happy.

Mu Yang seldom patrols the employees' offices, and will increase the pressure on them for no reason, and their leaders will not put pressure on them again.

But Mu Yang will often patrol the workshop and laboratory. Now he will not ask about the specific work, but just take a general look at how the site is managed. Only in the laboratory, he will seriously watch the progress of the project.

If the progress of the development project is stuck, he will pay close attention to it, give pointers if necessary, and let them make mistakes and learn a lesson if there is no need for guidance.

If the progress of a small project affects the progress of the overall project, Mu Yang will put pressure on it so that employees cannot relax too much.

The work environment management that is completely ignored by the Internet is not suitable for mechanical research. Muyang’s management philosophy is that it will not be too strict and does not require overtime, but the work items must be determined by people, standards and time. The time point must be checked and accepted, and the execution must have feedback.

He doesn't care about the process, but when it's time to close, the superiors will check the progress.

...

One night, when Mu Yang's family was eating, Malan asked his son:

"Son, I heard you made an appointment with Ma Yun from Ali or something?"

When Mu Yang heard his mother's question, he replied casually: "Yes, Mom, why are you paying attention to these things?"

"I heard that the person looks a bit weird, is it true?"

"Mom, there is something wrong with you. You listen to other people's nonsense. Strange people have strange looks. Maybe one day, your son will be the same as an alien in the eyes of others." Mu Yang replied seriously. The appearance of others is a manifestation of lack of quality, even if it is a mother, she still criticizes it.

"Well, I'm just curious, but don't tell me, when people ask me how I gave birth to such an outstanding son, I feel that others look at you like an alien." Malan laughed.

Mu Yang rolled his mother's eyes and continued to eat.

After dinner, I went for a stroll in the community with my wife.

The temperature is relatively low at night, but it has not yet reached below zero. It is not bad to go out to get a breath of stuffiness. Go shopping and come back for entertainment.

Mu Yang has no interest in playing games anymore. In 2011, games such as Crossfire, League of Legends, Asking, and World of Warcraft were the most popular.

At ten o'clock in the evening, Mu Yang saw his parents staying in the bedroom and watching TV before going to bed, so he reminded them not to be so polite to Song Xuelu, and not to give her food and make up for her.

It is not a good thing to be too polite to a person, and it is unnatural for everyone to get along.

This is how young people and old people live in the same house. Their living habits are different, and mother-in-law and daughter-in-law are prone to conflicts. Although Song Xuelu didn't say anything, Song Xuelu was a little embarrassed when Mu Yang saw her mother give her fruit to eat.

In fact, his daughter-in-law will get it herself if she wants to eat, or he will give it to her, and she will not be embarrassed.

"Mom, it's not nice of you to be so polite to Xuelu."

"Why not? I think it's pretty good."

"Oh, my god, if you go to someone else's house for dinner, and the host will give you a few pieces of meat, don't you feel embarrassed, it's okay once, if every meal is like this, do you feel annoying?" Mu Yang thought Communicating with the elderly is a bit difficult and tiring.

You can't say it directly, or the old man will be sad.

Malan smiled: "Your mother has never been treated so well."

"What I mean is, you should be as natural to Xuelu as you are to me and my sister. Of course, she didn't say anything. It's too polite, but it feels like an outsider."

"Well, I don't care that much."

"It's not that you don't care about that much, you misunderstood." Mu Yang felt that it was difficult to communicate. He left his mother's bedroom, took out some boxes of drinks that his mother didn't like to drink from the refrigerator, and returned to his mother's bedroom. Smiling: "Mom, let's have a drink."

"Your mother doesn't like these drinks." Malan directly refused.

"Oh, drink as soon as I give you a drink, don't be polite, don't be polite!" Mu Yang directly opened a box of drinks, inserted a straw, stuffed it into his mother's hand, and then stuffed it into his father's hand who couldn't figure out the situation .

The parents still finished drinking a box of drinks reluctantly, Mu Yang watched the parents finish drinking with a smile, and then continued to open a box: "Mom, drink another box."

"What are you doing? I won't drink it. It doesn't taste good at all. You can drink it yourself." After Ma Lan finished speaking, he looked at his son's crooked smile, "Why are you smiling?"

"Mom, what you do to me now is the same as what you did to Xuelu. It's not easy for Xuelu to refuse you, so she eats whatever you give her in a sullen breath." Mu Yang sighed He said in one breath, "You guys experience it slowly."

Mu Yang didn't take away the drink he brought, he put it on the table and left.

The most difficult problem in the world to solve is the relationship between mother-in-law and daughter-in-law.

Mu Yang felt that it was more difficult than managing the company.

This is also something that the system can't help him with. Mu Yang is someone who has experienced it, and he can perceive his wife's thoughts. After a long time, she will be very depressed.

Ma Lan looked at the drink he didn't want to drink in his hand, and then at the drink on the table, lost in thought.

the next day,

When Mu Yang returned to the company, he continued to focus on solving the motor issue.

The Hummer EV will be equipped with a permanent magnet synchronous motor instead of outsourcing.

It is also the most widely used motor for new energy vehicles in the future, accounting for more than 90% of installed capacity.

In the future, mainstream electric vehicles in Europe and the United States will use or plan to use asynchronous induction motors, while rejecting permanent magnet synchronous motors, such as Tesla.

An obvious disadvantage of permanent magnet synchronous motors is that the permanent magnet materials are expensive, often accounting for more than 50% of the overall material cost.

Permanent magnet materials need rare earth resources, and rare earth resources are extremely scarce in foreign countries, and the price is high and rare.

However, Huaguo owns more than 70% of the world's easy-to-mine rare earth resources, and is known as the "Kingdom of Rare Earths". Most of the world's rare earth materials are exported from my country, so this shortcoming does not exist in China.

However, due to cost reasons and some inexplicable reasons, European and American electric vehicles prefer to use asynchronous motors with large volume, heavy weight, and low overall energy efficiency, rather than permanent magnet synchronous motors.

Anyway, it's: I just don't need it, what can you do to me.

Not to mention, if Tesla uses a large number of permanent magnet synchronous motors and the rare earth gets stuck, it will really not be fun.

The layout method adopted by the Hummer EV dual motor is front + rear, and the three motors are front 1 + rear 2 layout.

The permanent magnet synchronous motor is not difficult to manufacture, but it is not easy to do it well.

According to the performance of technical difficulty, the following are demagnetization phenomenon, control technology, poor anti-black ability, limited high speed, and difficulty in starting.

The key component in the permanent magnet motor is the magnet, and the magnet is most afraid of high temperature. It will gradually demagnetize under the high temperature for a long time. The higher the temperature, the greater the risk of demagnetization.

Once the magnetization is demagnetized, the speed is astonishing, and the current of the motor will continue to increase after partial demagnetization, and the energy consumption will increase, which will increase the electricity cost of the user, and at the same time, there is the possibility of the motor "strike" at any time.

Therefore, an important indicator of the performance of permanent magnet motors is the high temperature resistance level. If it exceeds its temperature resistance level, its magnetic flux density will drop sharply, generally not exceeding 150 degrees Celsius.

The source of high temperature is mainly the high temperature generated by the motor running for a long time, the high temperature of the environment, and the accumulation of heat.

The new motor technology of Xinghai Group solves the problem directly from the source and develops new high heat resistance and high magnetic NdFeB permanent magnets. At the same time, improve the anti-magnetization technology, optimize the cooling system, etc.

Within two days, Mu Yang finally solved the demagnetization problem, and the progress of the motor project has taken a big step forward.
