Chapter 115 Frequency Control Technology

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

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

According to Hideo Tanaka's investigation, China's motor frequency conversion technology research started relatively late, and only a few large state-owned motor companies and research institutions have started and tried research on frequency conversion technology. He believes that small companies like Tang Fei must not have mastered it. Motor frequency conversion speed regulation technology.

Unexpectedly, in the experiment just now, Hideo Tanaka was slapped severely, and even Takeshitarou next to him also changed his face drastically.

It can be seen from the various data on the instruments of the comprehensive test bench that the motor of Jiuzhou Industrial Co., Ltd. is obviously superior in speed regulation performance.

If the previous starting performance test is only slightly advantageous, then the current speed control accuracy test is a decisive judgment!

Some knowledgeable technicians of the Red Star Factory also shouted, "My God, my eyes are not mistaken, Jiuzhou Industrial's motors are obviously much better in terms of speed regulation performance."

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

For speed-adjustable motors, what is the core technology? There is no doubt that it is frequency conversion speed regulation technology. Whoever masters the advanced frequency conversion speed regulation technology will master the core technology of this motor.

For motors, the development of frequency conversion motors will be a very important development direction. With the development of industry, all walks of life have higher requirements for motors, and they are demanding the use of speed-adjustable motors with advanced performance.

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

Using frequency conversion speed regulation technology, not only can realize stepless speed regulation, but also according to different loads, by properly 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. During the development process, Tang Fei also gave some good suggestions.

For example, reminding Luo Dong that they focused on the topology and control method of the frequency converter for in-depth research, and even Tang Fei made a proper "reminder".

Sometimes, the core key technology is only separated by a layer of paper. Before it is revealed, it feels very profound and remarkable. After being revealed, it is just the same thing.

As a well-known motor expert, Luo Dong was reminded by Tang Fei, and suddenly realized that some problems that had troubled him for many years were all solved, so he got this very high-tech motor, which uses very advanced frequency control technology.

Through the test just now, this motor is greatly surprised!
As the top leader, Chang Jinlin knows some technologies, but it is not his expertise. His expertise lies in enterprise management.

He saw everyone's reaction was so great, especially some technicians' eyes lit up, as if they had discovered something strange, Chang Jinlin was very curious and couldn't help asking.

"Old Xie, what's the matter, Tang Fei's motor is very good, isn't it!"

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

What, more advanced frequency control technology than RB motor!
Chang Jinlin was surprised 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-adjustable motors, frequency conversion technology is the core technology, and whoever masters it is more advanced. Whoever has mastered the frequency conversion technology of speed-regulating motors.

Cow!

Many people looked at Tang Fei with admiration. No one thought that Jiuzhou Industrial Co., Ltd., a small factory with only 300 to [-] employees, would have such incredible technical strength.

Xie Zhenhua thought in his heart that Tang Fei's ability to master such advanced frequency control technology may have something to do with Professor Luo Dong.

He was only half right in guessing that this advanced variable frequency speed regulation technology really came from Professor Luo Dong, but without Tang Fei's breakthrough, Luo Dong would still be wandering outside the gate of this advanced technology. After Tang Fei's breakthrough, he suddenly realized, This advanced frequency conversion speed regulation technology was mastered.

In this round, the RB people lost completely. The faces of Hideo Tanaka and Takeshitaro who were full of confidence were very ugly and embarrassed.

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

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

From the tone of his voice, it could be heard that Hideo Tanaka no longer had the confidence he had before, but rather lacked confidence.

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

In the industry, the energy consumption of motors accounts for more than 60% of the total industrial power consumption. AC motors realize speed regulation, and energy saving can reach more than 30%, or even 50%. The market needs this kind of motor. At this time, domestic speed regulation can be done. Motors, and there are very few companies that do a good job, and imported speed-adjustable motors are very expensive. For example, the price quoted by these RB people is as high as [-] for one.

The energy saving of the motor and the high efficiency of electric energy utilization are also an important indicator of the excellent performance of the motor. The next thing to do is to detect the efficiency of the motor.

The test begins.

The two testers from the Red Star Factory were skilled and skilled in their movements. They immediately started this performance test, and the two motors started up at the same time.

The entire laboratory was quiet, only the comprehensive test bench and the sound of the two motors running, and everyone was engrossed in looking at the two motors, or paying attention to the display data of a meter on the test bench.

It didn't take long for Hideo Tanaka and Takeshitarou to look even more ugly. Anyone who is knowledgeable can tell at a glance that Tang Fei's motor is obviously better in terms of energy utilization efficiency.

"It's amazing!"

"incredible!"

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

"Yeah, their opponent is RB Motor, which claims to be world-class. I wouldn't believe it if I didn't see it with my own eyes!"

"..."

The technicians of the Red Star Factory were all elated, as if they had won a big victory, and a sense of pride rose in their hearts.

As Chinese people, they saw that the motors of Jiuzhou Industrial Co., Ltd. were so good, and they felt happy and proud for Tang Fei and the others.

Tang Fei also felt the concern on his face, and said in his heart, it is indeed the motor developed by Luo Dong and the others.

The detection of the electric energy utilization efficiency of the motor was finally completed, and the results were very obvious. Everyone looked at Chang Jinlin, waiting for his results to be announced.

Hideo Tanaka and Takeshitarou had gloomy faces, very ugly.
