Chapter 188 A bold plan, Nanshan Electric wants to overtake in a corner

A motor is essentially an electromagnetic device that uses the law of electromagnetic induction to convert or transmit electrical energy.

The power tools you see every day, including drilling, polishing, grinding, grooving, cutting, reaming and other tools, all require the use of motors.

Various home appliances, including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc., also need to use motors.

It can be said that although people don’t pay much attention to motors, they exist all the time in their lives.

Of course, motors are used so widely, it is impossible for Nanshan to deal with all types of motors right away.

That is simply unrealistic and unnecessary.

As the initial focus, we must first develop the motors used on the robot, and at the same time, develop the ones used on the machine tools.

Of course, generators and starters used in cars are already under development and will definitely continue to be developed.

As for other products, they will be developed slowly in the future.

If the stall is too big and too scattered, problems may arise.

"Mr. Cao, would it be too radical to directly use flat wires for the winding of this motor?"

"This requires very high production equipment for copper wires, as well as high quality requirements for copper wires. If you are not careful, a large number of scraps will appear."

Although Pan Jinxing is not a professional in motor research, as a machine tool expert, he naturally also studies motors.

During this period, Cao Yang spent all day in the laboratory, and naturally he spent most of his time researching with him.

"Although the production of flat wires is a bit more difficult, the advantages are too obvious."

"Under the same power, because the flat wire takes up less space, the outer diameter and volume of the motor can be reduced, resulting in a smaller size, less material, and lower cost for the flat wire motor."

"Under the same volume, because the flat wire takes up less space, more wires can be filled in the slot while the entire space of the motor remains unchanged. That is, the slot fullness rate of the motor will increase, and the power density of the motor will also increase. Generally The slot full rate of round wire motors is about 40%, while you can achieve 60% slot full rate of flat wire motors.”

"Compared with round wire motors, flat wire motors can have a relatively smaller notch size, which can effectively reduce cogging torque, thereby reducing motor noise."

“Flat wire motors have better armature stiffness compared to round wire motors.”

"The internal gaps in the flat wire motor windings are small, and the contact area between the wires and the windings and the core slots is larger. Therefore, the heat dissipation and thermal conductivity are better, the temperature rise is lower, and the overall performance of the motor is better."

"For round wire motors, due to process problems, the ends are generally left slightly longer to prevent damage to the copper wire during the process, while for flat wire motors, because the wires are hard wires, the ends can be left shorter to save money. Copper materials, reduce costs and improve efficiency.”

Cao Yang knew very well that most of the motors used in electric vehicles in later generations were flat wires.

This is the way forward.

Since Nanshan wants to develop motors, it must develop in the right direction.

By planning ahead now, a bunch of patents will be able to keep out many competitors.

As a result, Nanshan's motors have become the industry leader.

As for the difficulties we are encountering now, they can definitely be solved.

Even if the defective rate is higher, it is still acceptable.

"Mr. Cao, you are right."

"But with flat wires, serial design is difficult. For example, when the core and the number of slots are the same, but the length and number of coil turns are different, a series of motors can be easily designed for round wire motors, while for flat wire motors because The number of turns itself is small, and reducing or adding a few will have a relatively large impact on the performance of the motor, so it is difficult to design a series.”

Pan Jinxing obviously still felt that Cao Yang's steps were too big.

Flat line.

Which manufacturer's mass-produced motors use windings like this?

If Nanshan has to be new and different, is it really useful?

“Design is hard to come back from, but it’s not impossible.”

"Look at the current plans, they all use flat wires. I have already designed the preliminary plans with several technicians."

“The next step is to consider introducing a batch of flat wire trial production lines yourself.”

"In the future, when the technology matures, special factories will be built for production."

Cao Yang pointed to the drawings on his computer and motioned to Pan Jinxing to take a look.

At the beginning, Pan Jinxing just glanced at it casually.

But soon, his eyes stopped moving.

It has only been less than half a month, and the design of the motor has been completed?

It looks decent, no obvious problems.

This……

How can this be?

"Mr. Cao, the structure of this motor seems to be completely different from the disassembled Fanuc motor."

"But there doesn't seem to be any problem. The structure is more compact and the weight is lighter."

Although Pan Jinxing was not a professional motor designer, he could still see the situation of the drawings in front of him at a glance.

"Why should it be the same as Fanuc's?"

"The motor on this FANUC robot was produced at least five years ago, and it was not the most advanced product at the time."

"If we design the structure the same as the other party, let's not talk about whether there is a problem with the patent."

"Technology alone will lag a lot, which is certainly not what we want to see."

"From a round line to a flat line, to a certain extent, we are overtaking on a curve."

"Although some manufacturers in the industry are doing research in this area, overall the progress is not particularly great."

"As long as we get it right, it can be used on many motor products in the future."

"Even with the increase in output, the problems in the flat wire processing process can be gradually solved, leaving only the advantages of flat wire."

When Cao Yang said this, Pan Jinxing naturally had no way to refute.

"Then I will arrange for people to build a trial production line as soon as possible. There is no manufacturer that can produce flat lines, so we can only do it ourselves."

"A motor is nothing more than a few key parts such as the stator and rotor."

“Among them, flat wires account for a relatively high cost because they are made of copper.”

"Even if we don't engage in in-house production now, we will do it sooner or later, otherwise the key points of cost will be in the hands of others."

"Anyway, we are just setting up a trial production line now. The output will be lower and the degree of automation will be lower. It doesn't matter."

"The key is to compress the time as much as possible. We can't keep Huaqiang Factory waiting for us."

"We can't let FANUC and the robot manufacturers just sit there and make money."

In 2002, a welding robot easily cost 60 yuan, or even millions.

But by 2023, the price will directly become 10,000+, or even less than 10.

On the contrary, the performance of the product has been improved.

It is conceivable that today's welding robots, even if they cannot be said to be huge profits, are definitely high-profit products.

Various manufacturers have also maintained a certain tacit understanding and will not easily engage in price wars.

Of course, once Chinese manufacturers enter this field, prices will start to drop.

Sometimes, Cao Yang didn't know how to evaluate this matter.

Chinese manufacturers have entered and prices have dropped, which is a good thing for users.

But if prices are reduced to a certain extent and disorderly competition occurs, it will actually do great harm to the industry.

Just like the export of motorcycles to Southeast Asia in recent years.

At the beginning, China's low-priced motorcycles were exported to Southeast Asia. In just a few years, the market share increased rapidly, leaving Japanese car companies in the dust.

But soon, a bunch of motorcycle manufacturers in China were swarming in exporting motorcycles to Southeast Asia.

After a few years, motorcycles will become cheap.

In order to compete on price, the quality became worse and worse, and the reputation gradually disappeared.

So by 2023, the motorcycle market in Southeast Asia will almost completely return to the hands of Japanese car companies.

Those domestic manufacturers, as crazy as they were back then, were disappointed later on.

But when you first start, you have to compete with international giants for the market, and it won’t work if you don’t compete on price.

You said that your technology is great, so you have to sell it at the same price as others, so that someone is willing to buy it.

Just like various shoe factories in China, are their technical levels really inferior to those of Adidas and Nike?

You must know that Adidas and Nike also use these manufacturers to manufacture their products.

But if you sell it yourself, you won't be able to sell it unless you sell it at a low price.

Robots are similar, and they also have brand effects.

So a price war is inevitable at the beginning.

It's just a matter of whether or not to fight so hard.

Once the price has been reduced to a certain level, if you lower it further, you may not be able to get more orders.

The degree here needs to be grasped well.

"No problem, the copper wire trial line will be ready soon."

Pan Jinxing did not question anything.

The boss's attitude is so obvious.

What are you still worried about?

……

"Chen Sang, are you sure that the Yangcheng Huaqiang Stamping Factory did not obtain robots from any manufacturer?"

As the head of the sales department of Fanuc China, Yoshida Nagamasa was more cruel to Nanshan than anyone else.

Because of the emergence of Nanshan CNC system, Fanuc's business in China plummeted.

Nowadays, except for a small number of manufacturers who have received advance payments before, they are still looking to FANUC to purchase CNC systems, and [-]% of customers have turned to Nanshan.

Originally, the products made by Fanuc were not as high-end as those of Siemens. Now Nanshan has come up with a CNC system that looks better in technology and cheaper. How can Fanuc still succeed?

What’s even more depressing is that Nanshan’s CNC system actually won the first prize of the China National Science and Technology Progress Award.

For FANUC, this was like a bolt from the sky.

If it weren't for the support of the robot business, FANUC's business team in China might consider disbanding.

"Minister, I have maintained communication with personnel from OTC, Kawasaki, Yaskawa, Fujikoshi and other manufacturers. This time everyone's position is very consistent."

"In the future, no matter what conditions Nanshan or Nanshan's related manufacturers offer, our robots will not be sold."

"Even other products, if Nanshan wants to buy them, try not to sell them as much as possible."

"Unless Nanshan can obtain better substitutes from other manufacturers, our position will not change."

When Chen Liang said this, he was very confident.

As one of Nanshan's victims, he is very motivated to deal with Nanshan.

He knew very well that if Nanshan was not suppressed, he would probably lose his job with less work and more money in the future.

“This time, the head of Toyota Motor Purchasing Headquarters personally contacted the presidents of each company and asked everyone to act in unison.”

"So far, Nanshan has caused huge losses to Aisin Seiki, and Aida has also lost most of the Chinese market."

"The other party has even begun to grab orders for Aisin gearboxes and Aida presses in the international market."

"We at FANUC are not the only victims, and we certainly will not be the last victims."

"You have to make the sales managers at Kawasaki and Yaskawa understand this truth."

"Otherwise, it will be ugly if everyone is not of the same mind and is defeated by others."

Yoshida feels that this time he can see the dawn of victory and there must be no surprises.

Robots are not only needed by Huaqiang Stamping Factory, but also by Nanshan if they want to automate various parts in the future.

Therefore, the earlier we start to restrict the sales of robots to Nanshan, the better the effect will be.

"Minister, don't worry, everyone understands this."

"Nanshan is a disruptor in the industry. He is just a piece of rat shit. He always does things that disgust everyone."

"We'll see how they develop if they make people angry."

"Fortunately, they provoked Aisin, which caused Toyota to step up and coordinate everyone to deal with them."

"Otherwise, if FANUC alone relies on us, some robot manufacturers may be reluctant to give up orders from Nanshan."

When Chen Liang said this, Yoshida couldn't help but nodded.

Toyota's influence in Japan's industrial industry is huge.

Although he can't be said to be the leading brother, his influence in the automotive-related fields is definitely unparalleled.

"After China's accession to the WTO, all walks of life have developed rapidly, and the demand for robots has also increased."

"If the company develops well, we will establish two separate sales departments under the sales department in the future. I have reserved the position of the chief of the first sales department for you."

When Yoshida said this, the smile on Chen Liang's face immediately became brighter.

I work so hard just for promotion and salary increase.

"Minister, during this time I have been thinking about how to break the situation in the CNC system."

"Actually, I don't think there is anything we can do."

"Nanshan has a cost advantage, is a local supplier, and is supported by policies."

"But we can definitely find cooperation with several local state-owned enterprises and produce CNC systems with them."

"At that time, we can use these state-owned enterprises to get orders."

"As for costs, for the CNC system, most of the R&D costs for us have been amortized."

"We can definitely take out some old systems and make some money again."

"Even if you can't make a lot of money, it will definitely make Nanshan disgusting and make their business difficult."

Chen Liang felt that he needed to show his loyalty to the company again before he could confirm the position of section chief.

Soon, Yoshida discussed this plan with him enthusiastically.

They have all been in China for many years and know that some companies are actually very enthusiastic about self-research on CNC systems.

If we can help them complete their tasks and come up with a win-win solution, the possibility is still very high.
