Ian Donnelly was indeed a little frightened, the fifth-generation IGBT, as far as he knew, a large electrical group in the United States, seemed to have just successfully developed the fourth-generation IGBT.

The commercial sensibilities made him dare not take it lightly, and immediately fed back the news back to his US headquarters, including the introduction materials of these IGBTs, the list of models, and so on.

Soon, Ian Donnelly received a call from his boss from the U.S. headquarters, this IGBT has excellent performance, they need it in large quantities, and instructed Ian Donnelly to go to Jiuzhou Industrial Co., Ltd. to order this IGBT in large quantities.

So, Ian Donnelly took a plane to Gangnam Province.

Before he came, he didn't forget to make a phone call to tell Yang Chenglin that he had a good personal relationship with Yang Chenglin, and Yang Chenglin was also polite, and personally drove to the provincial airport and picked up Ian Donnelly and his assistant.

After picking up the person, Yang Chenglin made a phone call to report to Tang Fei, and then drove back to Jiuzhou Industrial Co., Ltd.

In the office.

Tang Fei was talking to Wang Hailong about some work matters, and Zhao Ke was also sitting next to him. There is a professional electrical plant that is about to be built, and it can be put into use before the end of the year.

Used to make USB flash drives!

USB flash drives have been mass-produced in the United States, completely in short supply, and quickly began to replace 3.5-inch floppy disks, and the market demand is huge.

In the European market, USB flash drives have also begun to appear, which are manufactured by American companies in European factories, and according to the original authorized production agreement, Jiuzhou Industrial Co., Ltd. will receive a US dollar for each USB flash drive produced.

Don't underestimate this dollar, with the current production and manufacturing volume, this alone will bring a lot of income to Jiuzhou Industrial Co., Ltd.

U disks have also begun to appear in the domestic market, which are basically brought by people from the United States or from Europe, which are very expensive.

But many people in China are still flocking to it, hoping to have such a USB flash drive, because it is better than the 3.5-inch floppy disk that is currently widely used.

Seeing that the Chinese people were so eager to have a USB flash drive of their own, Tang Fei decided to manufacture it and then put it into the domestic market.

After listening to Tang Fei's decision, Wang Hailong said in his heart, I guessed correctly, this electrical plant that is about to be completed is really used to produce and manufacture USB flash drives.

From Wang Hailong's business point of view, once the production and manufacturing of USB flash drives begins, it will definitely bring very rich income to the company.

Tang Fei said some matters related to the production of USB flash drives, USB flash drives were invented by Tang Fei, and no one knows its production and manufacturing better than Tang Fei.

Zhao Ke carefully wrote down what Tang Fei said in the notebook, starting from today, he will start to prepare for the production and manufacturing of USB flash drives, such as process layout, selection of production equipment, preparation of production process technical data, etc.

Soon after talking about the production and manufacturing of the USB flash drive, Tang Fei's phone rang, this is a new phone from Tang Fei, and the previous Motorola has been honorably retired.

After entering 98 years, the domestic and international mobile phone market is developing rapidly, the replacement is also very fast, the price is getting cheaper and cheaper, compared with the previous mobile phone that can not move tens of thousands, or even 20,000 or 30,000 yuan, the mobile phone is now more and more powerful, the volume is getting smaller and smaller, and it is getting cheaper and cheaper.

The middle and senior managers of Jiuzhou Industrial Co., Ltd. each have mobile phones, and even some front-line workers have begun to have their own mobile phones, which is unimaginable two years ago.

Tang Fei said at the beginning that after two or three years, everyone can afford to buy a mobile phone, and now it seems that Tang Fei is not bragging at all.

On the one hand, mobile phones are getting cheaper and cheaper, and on the other hand, the treatment of Jiuzhou Industrial Co., Ltd. is getting better and better, and the treatment level of ordinary workers has definitely exceeded that of Hongxing Factory, and the treatment of management personnel is higher.

The mobile phone on the desk rang, Tang Fei picked it up and saw that it was Yang Chenglin calling, and before answering the phone, he said with a smile: "Chenglin should have picked up someone, and he is probably on his way back." ”

Sure enough, as soon as the phone was heard, Yang Chenglin said: "Boss, I have already picked up Ian Donnelly, and they are two of them, and they will return to the company in about half an hour." ”

Tang Fei told him to pay attention to safety on the road, and after answering the call, Tang Fei said: "Ian Donnelly is here, probably to order our IGBT, they should be the fourth customer of our IGBT products." ”

Half an hour later.

A small car drove into the gate of Jiuzhou Industrial Co., Ltd., and it was Yang Chenglin and Ian Donnelly who got out of the car.

Ian Donnelly looked at the familiar three-story building in front of him, and said slowly: "It's been a long time since I've been here, well, maybe it's been a year." ”

Yang Chenglin smiled slightly and invited: "Let's go, let's go upstairs, the boss should already be waiting for us upstairs." ”

Ian Donnelly and Tang Fei are also more familiar with each other, and they have confessed many times, and the two sides met, exchanged pleasantries, and said a lot with a smile.

Tang Fei invited Ian Donnelly to wait in the reception room, everyone sat down, drank tea or coffee first, chatted about some trivial matters like old friends, and there was hearty laughter from time to time.

After chatting for a while, Ian Donnelly said: "Don, we have carefully understood your IGBT, and I want to order your IGBT this time." ”

No problem with this, welcome with both hands raised!

Between the two sides, Ma Shan talked about the ordering of IGBT, and the price was nothing to talk about. The delivery date starts four months later, and the goods are picked up from Jiuzhou Industrial Co., Ltd.

Some details were negotiated quickly and showed a high level of efficiency. The contract is also being drawn up, and there should be no problem in signing a formal contract in the afternoon.

After talking about the IGBT order, Tang Fei thought that the business had been discussed, but who knew that Ian Donnelly gave himself another surprise.

Ian Donnelly said directly: "Don, you are a company that makes motors, and the performance and quality of the motor are still very good, we have a need for a motor, are you sure to make it." ”

"Oh. Tang Fei looked at Ian Donnelly.

Ian Donnelly waved his hand slightly, and his assistant took out a technical document and sent it to Tang Fei, which contained a series of technical requirements for this motor, including the main size, as long as the performance parameters were required, and so on.

It's a servo motor!

Tang Fei can see at a glance that this kind of motor is used a lot in the field of CNC machine tools, and with the development of the CNC machine tool industry, the market demand for this motor will be more and more large.

The production and manufacturing of high-end servo motors have been monopolized and controlled by foreign enterprises for a long time, and it is difficult for Chinese enterprises to import high-end servo motors.

Tang Fei was thinking that since his factory here is positioned as a motor manufacturing base, the servo motor must be developed and manufactured.

Originally, they planned to start developing their first servo motor next year, but they didn't expect that the opportunity came so suddenly, and Ian Donnelly wanted to help them develop and produce this servo motor.

Then let's start now, don't wait until next year.

Servo motor refers to a motor that controls the operation of mechanical components in a servo system.

The servo motor can make the control speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly, in the automatic control system, used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

It is divided into two categories: DC and AC servo motors, and its main feature is that there is no rotation phenomenon when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.

At the 1978 Hannover Trade Fair, the German company officially launched the first servo motor and drive system, which marked the official practical application of servo motor technology.

Naturally, since it is a motor, a servo motor is of course indispensable.

After reading the technical information provided by Ian Donnelly, Tang Fei knew that this is a servo motor with relatively high requirements, and its performance is quite advanced, but it has not reached the world's leading level.

Ian Donnelly did not dare to hand over the world's leading servo motor to Tang Fei to develop and manufacture, as far as he knew, Jiuzhou Industrial Co., Ltd. did not seem to have experience in developing and manufacturing servo motors, so the starting point could not be too high.

Seeing that Tang Fei finished reading this technical information, Ian Donnelly asked, "Don, is there a problem?"

Tang Fei replied: "There is no problem, this kind of servo motor, for us, there is no difficulty. ”

Ian Donnelly was relieved to receive such an answer.

Ian Donnelly began to talk to Tang Fei about the cooperation of servo motors, including trial production funds, future motor order price, order quantity, delivery date, etc.

After all this is negotiated, the contract is also being drawn up.

In the afternoon, a total of two contracts were successfully signed.

The first is a large contract, Ian Donnelly ordered a large number of IGBTs from Tang Fei, involving multiple models, and the total contract value is also more than 10 million US dollars, which is another large order of nearly 100 million yuan.

The second contract is about servo motors, although the value is not so big, but the prospects are good, Jiuzhou Industrial Co., Ltd. can take this opportunity to enter the field of servo motor research and development and manufacturing in one fell swoop.

After the contract was signed, Ian Donnelly went home happily that afternoon.

Since we want to make servo motors, we must first develop them, Tang Fei uses the old method to get the design outline out, do a good job of the framework, and then hand it over to Luo Dong and others for specific research and development.

Tang Fei remembered that although the servo motor at this time was technically mature, there were also some defects that could not be solved, such as deficiencies in zero drift, anti-interference, reliability, accuracy and flexibility, etc., which could not fully meet the requirements of motion control.

It was not until several years later, with the application of microprocessors and new digital signal processors DSP, that digital control systems appeared, and these above-mentioned deficiencies and defects of servo motors were perfectly solved.

Since you want to do it, then make the best servo motor.

………

Today's three watches, the second one is sent!
