Chapter 204 Servo Motors
Ian Donnelly was a little scared. As far as he knows, a large electrical group in the United States seems to have just successfully developed the fourth-generation IGBT.

He did not dare to underestimate the sensitivity of the business, and immediately fed back the news to his US headquarters, including the introduction materials of these IGBTs, the model list, and so on.

Soon, Ian Donnelly received a call from his boss from the US headquarters. This kind of IGBT had excellent performance and they needed it in large quantities. He ordered Ian Donnelly to go to Jiuzhou Industrial Co., Ltd. to order a large number of this IGBT.

So, Ian Donnelly took a plane to Jiangnan Province.

Before he came, he didn't forget to call Yang Chenglin to tell him that he and Yang Chenglin had a good personal relationship, and Yang Chenglin was also polite. He drove to the provincial capital 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 about some work matters with Wang Hailong, and Zhao Ke was sitting beside him.A professional electrical factory building is about to be completed, and it can be put into use before the end of the year. Tang Fei already has a plan for what this factory building will be used for.

Used to produce USB flash drives!
U disks have been mass-produced in the United States, and the supply is completely in short supply. They quickly began to replace [-]-inch floppy disks, and the market demand is huge.

In the European market, USB flash drives also began to appear, which were produced by American companies in European factories. According to the original agreement on authorized production, Jiuzhou Industrial Co., Ltd. would get a commission of one dollar for each USB flash drive produced.

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

U disks have also begun to appear in the domestic market. Basically, some people brought them from the United States or Europe, and they are very expensive.

But many people in China are still flocking to it, hoping to have such a U disk, because it is better than the 01-inch floppy disks currently widely used.

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

Hearing Tang Fei's decision, Wang Hailong said in his heart, I guessed right, this electrical factory building that is about to be completed is really used to produce USB flash drives.

From Wang Hailong's business point of view, once the production of USB flash drives starts, it will definitely bring a lot of income to the company.

Tang Fei talked about some matters related to the production of the USB flash drive. Tang Fei invented the USB flash drive, and no one knows its production better than Tang Fei.

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

Not long after talking about the production of the USB flash drive, Tang Fei's phone rang. This is Tang Fei's new phone. The previous Motorola has been honorably retired.

After entering 98, the domestic and international mobile phone market has developed rapidly, and the replacement is also very fast, and the price is getting cheaper and cheaper. It's getting more powerful, smaller, and cheaper.

Everyone in the middle and senior management of Jiuzhou Industrial Co., Ltd. has a mobile phone, and even some front-line workers have begun to have their own mobile phones. This was unimaginable two years ago.

Tang Fei said at the beginning that after two or three years, everyone will be able to afford a mobile phone. Now it seems that Tang Fei is not bragging at all.

On the one hand, mobile phones are getting cheaper and cheaper. On the other hand, the treatment of Jiuzhou Industrial Co., Ltd. is getting better and better. The treatment level of ordinary workers has definitely surpassed that of Red Star Factory, and the treatment of management personnel is even higher.

The mobile phone on the desk rang. Tang Fei picked it up and saw that it was Yang Chenglin calling. 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, when he heard the phone call, Yang Chenglin said, "Boss, I have already connected with Ian Donnelly. The two of them will return to the company in about half an hour."

Tang Fei reminded him to pay attention to safety on the road. After answering the call, Tang Fei said, "Ian Donnelly is here. He probably wants to order our IGBTs. They should be the fourth customer of our IGBT products."

After half an hour.

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, "I haven't been here for a long time, um, it may have been a year."

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

Ian Donnelly and Tang Fei are also relatively familiar with each other, and they have talked to each other many times. When the two sides met, they exchanged pleasantries and talked a lot with a smile.

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

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

This is no problem, hands up welcome!

Ma Shan talked about the ordering of IGBTs between the two parties. There is nothing to discuss about the price, and the price is clearly marked.The delivery date starts four months later, with pick-up from Jiuzhou Industrial Co., Ltd.

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

After talking about the IGBT order, Tang Fei thought that the business was over. How could he know that Ian Donnelly gave himself another surprise.

Ian Donnelly said directly: "Don, you are a motor company, and the performance and quality of the motor are still very good. We have a need for a motor. Are you sure you can 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 dimensions, as long as the performance parameter requirements and so on.

This is a servo motor!
Tang Fei could tell at a glance that this kind of motor is widely used in the field of CNC machine tools. With the development of the CNC machine tool industry, the market demand for this kind of motor will increase.

The manufacture of high-end servo motors has been monopolized and controlled by foreign companies for a long time, and it is relatively difficult for Chinese companies to import high-end servo motors.

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

Originally planned to start developing their first servo motor next year, unexpectedly, the opportunity came so suddenly, Ian Donnelly wanted to help them develop and produce this servo motor.

Then start now, don't have to wait until next year.

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

The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal 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, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal Converted to angular displacement or angular velocity output on the motor shaft.

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

The German company officially launched the first servo motor and drive system at the Hannover Trade Fair in 1978, which marked that the servo motor technology officially entered the practical stage.

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

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 for R&D and production. As far as he knew, Jiuzhou Industrial Co., Ltd. seemed to have no experience in R&D and manufacturing of servo motors, so the starting point should not be too high. .

Seeing Tang Fei finish reading the technical information, Ian Donnelly asked, "Don, do you have any questions?"

Tang Fei replied: "No problem, this kind of servo motor is not difficult for us."

With such an answer, Ian Donnelly was relieved.

Ian Donnelly began to talk with Tang Fei about the cooperation of servo motors, including the cost of trial production, the order price of future motors, the order quantity, delivery date and so on.

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

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

The first is a big contract. Ian Donnelly ordered a large number of IGBTs from Tang Fei, involving multiple models, and the total contract value exceeded 1000 million US dollars. This is another large order of nearly [-] million yuan.

The second contract is about servo motors. Although the value is not so great, the prospect is good. Jiuzhou Industrial Co., Ltd. can use this as an opportunity to enter the field of research and development and manufacturing of servo motors in one fell swoop.

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

Since the servo motor is going to be done, it needs to be researched and developed first. Tang Fei used the old method to get out the design outline, complete the frame, and then hand it over to Luo Dong and others for specific research and development.

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

Until several years later, with the application of microprocessors and new digital signal processors (DSP), digital control systems appeared, and these above-mentioned deficiencies and defects of servo motors were perfectly resolved.

Since it is going to be done, make the best servo motor.
