Rebirth 2008: I Can Make Money Reading Chapter 330

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

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

Cai Xiaokun and Mukun look a bit similar. When the personnel department recommended him the office director, this made Mu Yang pay more attention to him.

Of course, Cai Xiaokun's own ability is indeed very strong. With Mu Yang's approval, he decided to let him serve as the office director for a three-month trial.

"Hello, Chairman!"

When Cai Xiaokun and the two secretaries saw Mu Yang walking in, they quickly greeted him respectfully.

Mu Yang glanced at Cai Xiaokun, suddenly remembered Moukun, stood in front of his desk, and asked softly, intentionally or not, "Xiaokun, can you play basketball?"

Cai Xiaokun thought that the chairman asked him about his work. He felt a little surprised when he was asked about basketball. After a little thought, he 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, hehe, my level is too low, I can't play." Mu Yang laughed lightly.

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

Cai Xiaokun said modestly: "Xiao Luo has won the prize, so I'm just average. Besides, when it comes to playing, the level is not important, just have fun."

"Yes, if you don't compete, the level is not important, the focus is on entertainment." Mu Yang agreed with this statement, "You guys are busy."

Seeing the chairman leave, Cai Xiaokun couldn't understand the meaning of the chairman's question.

Test his amateur activity level by asking basketball? See if you have the ability to organize company events?

Or through words, to see how well he communicates?

Or through dialogue, to see how his emotional intelligence is?

Cai Xiaokun has many guesses. He feels that the chairman is a busy person, and he will never be bored to ask these things.

But he would never have thought that the chairman asked him, really unintentionally.

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 occasionally. The chairman asked you, maybe he suddenly became interested and wanted to invite you to play basketball together." Luo Zhize shook his head.

"It's not easy to play basketball with the chairman." 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, not too serious, but not too fake. The most important thing is to make the leader happy.

Muyang seldom patrols the staff's office, which will increase pressure on them for no reason, and their leaders will put pressure on them if they can't get it right.

But Muyang often patrols the workshop and laboratory. Now he doesn't ask about the specific work. He just looks at the general situation and sees how the site is being managed. Only in the laboratory, he will carefully watch the progress of the project.

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

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

The Internet's completely irrelevant work atmosphere management is not suitable for application in mechanical research. Muyang's management philosophy is that it will not be too strict and do not require overtime, but the work project must be determined by people, standards and time. The time point must be accepted, and the execution must have feedback.

He doesn't care about the process, but when it comes to the closing time, the leaders above will check the progress.

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

"Son, I heard that you have an appointment with Ma Yun from Ali?"

Hearing his mother's question, Mu Yang replied casually, "Yes, Mom, why are you paying attention to this?"

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

"Mom, this is a bit wrong. You listen to other people's nonsense, and strange people have strange appearances. Maybe one day, your son will be like an alien in the eyes of others." Mu Yang replied seriously, commenting on the evaluation. The appearance of others is a very unqualified manifestation, even if it is a mother, it is still criticized.

"Okay, 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 see you like an alien." Ma Lan laughed.

Mu Yang gave his mother a blank look and continued to eat.

After dinner, I walked around the neighborhood with my daughter-in-law.

At night, the temperature is relatively low, but it has not yet reached below zero. It is not bad to come out and get some stuffy air. After a walk around, come back for entertainment.

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

At ten o'clock in the evening, Mu Yang saw that his parents were staying in the bedroom watching TV and hadn't slept, so he told his parents that they should not be so polite to Song Xuelu, not to give her food to make up for it.

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

This is how young people and old people share a house. Living habits are different. Mother-in-law and daughter-in-law are prone to conflicts. Although Song Xuelu didn't say it, Song Xuelu felt a little embarrassed when Mu Yang saw her mother bring her fruit to eat.

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

"Mom, it's not good for you to be so polite to Xue Lu."

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

"Oh, my mother, if you go to someone else's house for dinner, and the host will give you a few pieces of meat, you will feel embarrassed. It's fine once. If it's like this every meal, do you feel annoyed?" Mu Yang thought. It's a little difficult to communicate with the elderly, and it's more tiring.

I can't say it directly, otherwise the old man will be sad.

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

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

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

"It's not that you understand it wrong." 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 went back to his mother's bedroom. With a smile: "Mom, have a drink."

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

"Oh, just drink it for you, you're welcome, don't be polite!" Mu Yang directly opened a box of drinks, inserted a straw, put it in his mother's hand, and then put it in his father's hand, who couldn't understand the situation. .

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

"What are you doing? I'm not drinking anymore. It's not good at all. Drink it yourself." After Ma Lan finished speaking, she looked at her son's crooked smile, "Why are you smiling?"

"Mom, what you are doing now is the same as what you are doing to Xuelu. Xuelu is not good at rejecting you, so whatever you give her to eat, she will finish it all in a sigh." Mu Yang sighed. He said in one breath, "You can take it slow."

Mu Yang didn't take the drink he brought, just 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.

Muyang feels more difficult than managing the company.

This is also something the system can't help him. Mu Yang is a past person and can detect his daughter-in-law's thoughts. Over time, she will be very depressed.

Malan looked at the drink he didn't want to drink in his hand, and then looked at the drink on the table, and fell into contemplation.

the next day,

Muyang returned to the company and focused his work on the motor.

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 the installed capacity.

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

An obvious disadvantage of permanent magnet synchronous motor is that the permanent magnet material is expensive, which often accounts 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 very high.

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

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

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

Not to mention, if Tesla Servo uses a large number of permanent magnet synchronous motors and rare earths are stuck, it will be really no fun.

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

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

According to the performance of technical difficulty~www.mtlnovel.com~, the order is demagnetization phenomenon, control technology, poor anti-black ability, limited high speed, difficult start and so on.

The key component in the permanent magnet motor is the magnetic steel, and the magnetic steel is most afraid of high temperature, which will gradually demagnetize under a long-term high temperature state. The higher the temperature, the greater the risk of demagnetization.

Once demagnetized, the speed is amazing, and after partial demagnetization, the current of the motor will continue to increase, and the energy consumption will increase, which will increase the user's electricity cost, and there is a possibility that the motor will "strike" at any time.

Therefore, an important indicator of the performance of a permanent magnet motor 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 main source of high temperature is the long-term operation of the motor will generate high temperature, high ambient temperature, heat accumulation, etc.

Xinghai Group's new motor technology solves the problem directly from the source, and develops new high heat resistance, high magnetic NdFeB permanent magnets. At the same time, the anti-magnetization technology is improved, and the cooling system is optimized.

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