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

The power tools we see every day, including drilling, polishing, grinding, grooving, cutting, reaming and other tools, all need to use motors.

Motors are also needed for all kinds of household appliances, such as washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.

It can be said that although we don't usually pay much attention to the motor, it exists all the time in our own lives.

Of course, the use of motors is so extensive, it is impossible for Nanshan to get all the types of motors as soon as they come up.

That's not realistic at all, and it's not necessary.

As the focus of the initial stage, it must be to get the motor used in the robot first, and at the same time, to get the machine tool used.

Of course, the generators and starters used in automobiles have already been developed, and they will definitely continue to be developed.

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

If the stall is too large and too scattered, it is also prone to problems.

"Mr. Cao, is it too radical to use flat wire directly for the winding of this motor?"

"This has high requirements for the production equipment of copper wire, and the quality requirements for copper wire are also very high, and a large number of waste products will appear if you are not careful."

Although Pan Jinxing is not a professional researcher of motors, as a machine tool expert, he naturally has studied motors.

During this time, Cao Yang soaked in the laboratory all day long, and he naturally had to study with him most of the time.

"Although the difficulty of making flat wire is a little higher, the advantages are too obvious."

"At the same power, because the flat wire occupies less space, the outer diameter and volume of the motor can be reduced, resulting in a smaller volume, less material and lower cost of the flat wire motor."

"Under the same volume, because the flat wire occupies a small space, under the condition that the entire space of the motor remains unchanged, more wires can be filled in the slot, that is, the slot filling rate of the motor will be increased, and the power density of the motor will also be increased. Generally, the slot filling rate of round wire motors is about 40%, while the slot filling rate of flat wire motors can reach 60%. ”

"Compared with round wire motors, flat wire motors can take a relatively small notch size, which can effectively reduce the cogging torque, thereby reducing the noise of the motor."

"Flat wire motors have better armature stiffness compared to round wire motors."

"The internal void of the flat wire motor winding is small, and the contact area between the wires and between the windings and the core groove is larger, so the heat dissipation and thermal conductivity are better, the temperature rise is lower, and the overall performance of the motor is better."

"Round wire motors, because of process problems, the end is generally left slightly longer to prevent damage to the copper wire in the process, while the flat wire motor, because the wire is a hard wire, so the end can be left shorter, saving copper, reducing costs and improving efficiency."

Cao Yang is very clear that most of the motors used in electric vehicles in later generations are flat wires.

This is the direction of the future.

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

Now lay out in advance, and then a bunch of patents can keep many competitors out.

So that Nanshan's motor has become the leader of the industry.

As for the difficulties encountered now, they can be solved.

Even if the defect rate is higher, it is acceptable.

"Mr. Cao, what you said is not wrong."

For example, in the case of the same number of cores and slots, but the length and number of coil turns are different, the round wire motor can easily design a series of motors, and the flat wire motor has a relatively large impact on the performance of the motor because the number of turns itself is small, and it is difficult to make a series of designs."

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

Flat line.

Which manufacturer now uses such winding for mass production motors?

Nanshan has to be different, is it really useful?

"It's not impossible to design."

"You see, these solutions are all using flat wire schemes, and I have designed the preliminary scheme with a few technicians."

"The next step is to directly consider introducing a batch of flat line trial production lines by yourself."

"In the future, when the technology is mature, a special factory will be built to produce it."

Cao Yang pointed to the drawings in 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's only been less than half a month, and the design of the motor has been completed?

It looks like it's presentable, and there's nothing obvious about it.

This......

How is this possible?

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

"But it doesn't look like there's any problem, it's more compact and lighter."

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

"Why should it be the same as Fanuco?"

"The motor on this Fanuc robot was at least five years old, and it was not the most advanced product at that time."

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

"It's going to be a lot behind in terms of technology alone, and that's certainly not what we want to see."

"From a round line to a flat line, in a way, we're overtaking in a corner."

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

"As long as we do it well, 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, so that the flat line only has the advantages."

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

"Then I will arrange someone to do the trial production line as soon as possible, there is no manufacturer of the flat line that can be produced, so we can only do it ourselves."

"The motor is nothing more than a stator, rotor and so many other key parts."

"Among them, the flat wire is made of copper, and the cost proportion is relatively high."

"Even if we don't engage in internal control now, sooner or later we will have to do it, otherwise the key point of cost will be in the hands of others."

"Anyway, it's just a trial production line now, the output is lower, the degree of automation is lower, it doesn't matter."

"The key is to compress time as much as possible, and we can't let Huaqiang Factory wait for us all the time."

"You can't let Fanuc and those robot manufacturers lie there all the time to make money."

In 2002, a welding robot cost 500,000 or 600,000 yuan, or even millions.

But in 2023, the price will directly become hundreds of thousands, or even less than 100,000.

And the performance of the product has been improved.

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

Various manufacturers have also maintained a certain tacit understanding and will not easily fight a price war.

Of course, once there are Chinese manufacturers in this field, prices will begin to fall.

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

Huaxia manufacturers have entered, and the price has dropped, which is a good thing for the user.

However, if the price is reduced to a certain extent and disorderly competition is engaged, then in fact, the damage to the industry is great.

Just like in recent years, motorcycles have been exported to Southeast Asia.

At the beginning, Huaxia's low-cost motorcycles were exported to Southeast Asia, and the market share rose rapidly in just a few years.

But soon, a bunch of motorcycle manufacturers in China swarmed to export motorcycles to Southeast Asia.

After a few years, motorcycles directly became the price of cabbage.

In order to compete for price, the quality is getting worse and worse, and slowly the reputation is gone.

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

Those domestic manufacturers, how crazy they were back then, how lost they were.

But when you first started, you have to compete with international giants for the market, and you can't do it without fighting for price.

You say that you are a technical cow, you have to sell it at the same price as others, and someone must be willing to buy it.

Just like the shoe factories in China, is the technical level really inferior to Adi and Nike?

You must know that Adi and Nike are also looking for these manufacturers to OEM.

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

Robots are similar, the same is a brand effect in it.

So it was inevitable to start fighting a price war.

It's just a question of whether to fight so hard.

The price has been reduced to a certain extent, and if you lower it, you will not necessarily get more orders.

The degree of this needs to be grasped well.

"No problem, the trial line of copper wire can be done soon."

Pan Jinxing did not question anything further.

The attitude of the boss is so obvious.

What are you still struggling with?

……

"Chen Sang, are you sure that the Yangcheng Huaqiang Stamping Factory didn't get robots from any manufacturer, right?"

Yoshida Yongmasa, as the head of the sales department of Fanuc Huaxia, is more ruthless to Nanshan than anyone else.

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

Nowadays, except for a small number of manufacturers who have received advance payments before, they are still looking for Fanuc to buy CNC systems, and eighty percent of customers have turned to Nanshan.

Originally, Fanuc's products were not as high-end as Siemens, and now Nanshan has come up with a CNC system that looks better and the price is cheaper.

What's even more depressing is that Nanshan's CNC system has also won the first prize of the Chinese National Science and Technology Progress Award.

This was like a bolt from the ground yesterday for Fanuc.

If it weren't for the support of the robot business, Fanuc's business team in Huaxia could consider disbanding.

"Minister, I have been in communication with the personnel of OTC, Kawasaki, Yaskawa, Fujikoshi and other manufacturers, and this time everyone's position is very consistent."

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

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

"Unless Nanshan can get better alternatives from other manufacturers, our position will not change."

When Chen Liang said this, he was full of confidence.

As one of Nanshan's victims, his enthusiasm for dealing with Nanshan is very high.

He knows very well that if he doesn't suppress Nanshan, he will probably lose this job with less money and more money in the future.

"This time, the head of Toyota's Purchasing Headquarters personally contacted the presidents of each company and asked them to act in unison."

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

"They have even started to grab orders for Aisin gearboxes and Aida presses in the international market."

"We Fanuc are not the only victims, and we certainly won't be the last."

"You have to make the sales leaders of Kawasaki and Yaskawa understand this truth."

"Otherwise, when the time comes, everyone will not have the same heart, and they will be broken by others, and it will be ugly."

Yoshida felt that this time he could see the dawn of victory, and there must be no surprises.

The robot is not only needed by Huaqiang Stamping Plant, but also by Nanshan if it wants to carry out the automation transformation of various parts in the future.

So the sooner you start restricting bot sales to Nanshan, the better the effect.

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

"Nanshan is a spoiler in the industry, just a grain of rat, always doing disgusting things for everyone."

"When the time comes, we will make people angry, and see how they develop."

"It's also fortunate that they provoked Aisin, causing Toyota to stand up and coordinate everyone to deal with them."

"Otherwise, relying on us alone, it is estimated that some robot manufacturers are reluctant to give up orders from Nanshan."

As soon as Chen Liang said this, Yoshida couldn't help but nodded.

Toyota's influence in the industrial industry is huge.

Although it is not a leading big brother, in the field of automobiles, the influence is absolutely unparalleled.

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

"If the company develops well, I will set up two separate sales departments under the sales department in the future, and I will reserve the position of the head of the first sales section for you."

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

Isn't it just for a promotion and a salary increase?

"Minister, I've been thinking about how to break the situation in terms of CNC systems during this time."

"Actually, I don't think there's nothing I can do at all."

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

"But we can find a few local state-owned enterprises to cooperate and produce CNC systems with them."

"When the time comes, we can use these state-owned enterprises to get orders."

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

"We can come up with some old systems and make some more money."

"Even if you can't make a lot of money, it's definitely no problem to disgust Nanshan and make their business difficult."

Chen Liang felt that he needed to show his loyalty to the company again in order to implement the position of section chief.

Soon, Yoshida was excited to discuss this plan with him.

They have been in China for many years, and they know that some companies are actually enthusiastic about the self-development of CNC systems.

If you can help them complete the task and come up with a win-win plan, the possibility is still very high.

It's the end of the month, ask for a monthly pass
