The motors of both sides are speed-regulating motors, and the speed regulation accuracy is one of the main indicators reflecting the performance of the motor, and the speed regulation accuracy is reflected in the frequency conversion speed regulation technology.

Hideo Tanaka was originally very confident in his motors, especially in the frequency conversion speed regulation technology, they used the current international mainstream frequency conversion speed regulation technology, which is very mature.

According to Hideo Tanaka's investigation, Huaxia's motor frequency conversion technology research started late, only a few large state-owned motor enterprises and research institutions began and tried to study frequency conversion technology, he believes that small enterprises like Tang Fei, must not have mastered the motor frequency conversion speed regulation technology.

Who would have thought that the test just now slapped Hideo Tanaka hard, and even Takeshita Lang next to him also changed his face.

It can be seen from the data on the comprehensive test bench instrument that the motor of Jiuzhou Industrial Co., Ltd. is significantly better in terms of speed regulation performance.

If the previous starting performance test is only a slight advantage, then the current speed regulation accuracy test is superior!

Some knowledgeable technicians from the Red Star Factory also shouted, "My God, my eyes are not wrong, the motor of Jiuzhou Industry is obviously much better in terms of speed regulation performance." ”

"Yes, this shows that they have mastered the advanced frequency conversion speed regulation technology, which is amazing!"

For the speed control motor, what is the core technology, there is no doubt that it is the frequency conversion speed regulation technology, who has mastered the advanced frequency conversion speed regulation technology, who will master the core technology of this motor.

With the development of industry, all walks of life have increased their requirements for motors, and they have required the use of speed-regulating motors with advanced performance.

In recent years, the most active and fastest-growing AC speed regulation technology is the frequency conversion speed regulation technology. Variable frequency speed regulation technology is suitable for both asynchronous and synchronous motors.

The use of frequency conversion speed regulation technology can not only achieve stepless speed regulation, but also according to the different loads, by appropriately adjusting the relationship between voltage and frequency, the motor can always run in the high-efficiency area and ensure good dynamic performance.

This motor was developed and designed by Luo Dong and his team, and Tang Fei also gave some good suggestions during the research and development process.

For example, Luo Dong was reminded that they focused on the topology and control method of the inverter for in-depth research, and even Tang Fei made an appropriate "reminder".

Sometimes, the core key technology is only separated by a layer of paper, and before it is broken, it feels very profound and remarkable, and after it is broken, it is just the same thing.

As a well-known motor expert, Luo Dong was reminded by Tang Fei and suddenly realized that some of the problems that had plagued him for many years were all solved, so there was this very high-tech motor, which used very advanced frequency conversion speed regulation technology.

Through the test just now, this motor is greatly amazing!

As a leader, Chang Jinlin understands some technology, but it is not his specialty, his expertise is in the management of enterprises.

Seeing that everyone's reaction was so big, especially some technicians' eyes lit up, as if they had discovered something unusual, Chang Jinlin was very curious and couldn't help asking.

"Lao Xie, what's wrong, Tang Fei's motor is very good, isn't it!"

Xie Zhenhua is a technical talent, the chief engineer of the Red Star Factory, and he has two brushes in technology, he nodded and said: "Tang Fei's motor is obviously better in frequency conversion speed regulation technology, and it is estimated that it uses more advanced frequency conversion speed regulation technology than RB motors. ”

What, more advanced frequency conversion speed regulation technology than RB motor!

Chang Jinlin was startled at first, and then almost gave Tang Fei a thumbs up, even if he is not very proficient in motor technology, Chang Jinlin also knows that for speed control motors, frequency conversion technology is the core technology, who has mastered more advanced frequency conversion technology, who has mastered the frequency conversion technology of speed control motors.

Cow!

Many people looked at Tang Fei with admiration, and everyone didn't expect that Jiuzhou Industrial Co., Ltd., such a small factory with only two or three hundred people, would have such a strong technical strength.

Xie Zhenhua thought in his heart that Tang Fei and his ability to master such advanced frequency conversion speed regulation technology may have something to do with Professor Luo Dong.

He only guessed half right, this advanced frequency conversion speed regulation technology is indeed from Professor Luo Dong, but if there is no Tang Fei's point break, Luo Dong is still hovering outside the door of this advanced technology, after Tang Fei broke it, he suddenly realized that he mastered this advanced frequency conversion speed regulation technology.

In this game, the RB people lost completely, and the faces of Hideo Tanaka and Takeshita, who were originally full of confidence, were very ugly and embarrassing.

As the leader of the review team, Chang Jinlin basically had his own judgment, but in order to convince RB people, he said loudly: "Mr. Tanaka, Mr. Takeshita, there is still a motor efficiency test, do you want to continue?"

In the face of so many people, Hideo Tanaka had no steps to go down, gritted his teeth and said: "Tested the efficiency of the motor, our motor will definitely win in this performance." ”

It can be heard from the tone that Hideo Tanaka no longer has the confidence he had before, but a little lack of confidence.

Generally speaking, the frequency conversion technology of the speed-regulating motor is more advanced, and correspondingly, its power utilization efficiency is also higher, and the next step is to carry out this aspect of the test.

In the industry, the motor energy consumption accounts for more than 60% of the total industrial power consumption, AC motor speed regulation, energy saving can reach more than 30%, or even 50%, the market needs this kind of motor, at this time, the domestic speed motor can be done, and do very little enterprises, imported speed motor is very expensive, such as these RB people's quotation is as high as 28,000 sky-high price.

The motor is energy-saving, and the power utilization efficiency is high, which is also an important indicator to reflect the excellent performance of the motor.

The test begins.

The two testers of the Red Star Factory were experienced in technology and skillful in their movements, and immediately started this performance test, and the two motors started at the same time.

The whole laboratory was quiet, only the sound of the comprehensive test bench and the operation of the two motors, everyone was engrossed in watching the two motors, or paying attention to the display data of the instrument on the test bench.

It didn't take long for Hideo Tanaka and Takeshita Lang's faces to look even more difficult to see, as long as they were knowledgeable people, they could see at a glance that Tang Fei's motor was obviously higher in terms of power utilization efficiency.

"It's amazing!"

"Unbelievable!"

"I didn't think that the motor of Jiuzhou Industrial Co., Ltd. is so good, it wins in speed regulation performance, and it obviously wins in power utilization efficiency. ”

"Yes, their opponent is an RB motor that claims to be of the world's first-class level, if I don't see it with my own eyes, I won't believe it if I am killed!"

“……”

Those technicians of the Red Star Factory raised their eyebrows one by one, as if they had won a big victory, and the pride in their hearts rose spontaneously.

They are also Chinese people, and they are happy and proud of Tang Fei when they see that the motor of Jiuzhou Industrial Co., Ltd. is so good.

Tang Fei also felt that his face was related, and he said in his heart, it is worthy of the motor developed by Luo Dong, and the performance is a cow, which is obviously a level better than the similar motor of RB people.

The electric energy utilization efficiency test of the motor has finally been completed, and the results have been very obvious, and everyone has looked at Chang Jinlin, waiting for his results to be announced.

Hideo Tanaka and Takeshiro had gloomy faces and were very ugly.
