Chapter 179 Rare Earth Permanent Magnets (Subscribe)
"Mr. Ozawa, what do you mean by that? I don't seem to understand!"

Cao Guohua looked in surprise at Ichiro Ozawa, who was not tall but had a dignified face, and Cao Mao beside him was also full of puzzlement. As if there was something wrong with his ears, he just stared straight at Ichiro Ozawa, whom they hired from Japan at a high price, as if saying, what you said just now, old boy, is nonsense, right?

"What I said just now is very clear, you can't do this!" Ichiro Ozawa had no intention of taking care of the many high-level executives of Fengmao Company, so he said it bluntly.

Cao Guohua couldn't hold back immediately: "How is it possible? Why can't we Fengmao produce a low-quality product produced by a mainland manufacturer? We spent so much money on machinery and raw materials from Japan, and some of them hired other workers including your little one. A dozen or so Japanese technicians, including Mr. Ze, couldn't do it..."

Before he finished speaking, Cao Guohua stepped forward and grabbed Ozawa Ichiro by the collar, and shouted loudly: "Say, why can't you do it?"

Fortunately, the people next to him stopped him in time, otherwise the tall Cao Guohua would have almost swallowed the short Ichiro Ozawa alive.

In fact, it is no wonder that Cao Guohua is so excited. During this time, Swire Pacific has already filed a lawsuit against Fengmao Company in the Hong Kong Island Court. At the same time, HSBC’s move to shrink money has caused a chain reaction. Several banks have asked Fengmao Company to repay the loan in advance.

However, as the news that Fengmao hydrofoil surfboards in the European and American markets were largely unsalable spread to Hong Kong Island, several local consortiums in Hong Kong Island that were closely connected with Fengmao also chose to watch from the sidelines.

There is no way, it is because Fengmao Company produced a large number of hydrofoil surfboards after several rounds of capacity expansion some time ago, and these products were naturally highly valued by all walks of life because of the popularity of the European and American markets.

But now, a large area is unsalable, and these things piled up in the warehouse have become junk goods that everyone can't avoid.

The problem is that capital can leave as soon as it is said, without leaving nostalgia, but Fengmao Company can't, so Fengmao Company puts their hopes on their own upgrade suits.

Since the mainland manufacturers can do it, Fengmao can only do better.

The result can be...

"Mr. Ozawa, please forgive me, Guohua is also a little impatient. After all, the upgrade of the suit is related to the life and death of our Fengmao company, so please explain clearly why we can't do this kind of suit?" At this time, Cao Mao finally opened the door. He asked the housekeeper behind him to pull Cao Guohua down, and at the same time, stepped forward to hold Ichiro Ozawa's hand, and said earnestly, "Mr. Ozawa, please tell me the truth!"

I have to say that although Ozawa Ichiro is a bit rigid, he is very professional. Although he was very angry with Cao Guohua's actions just now, when facing Cao Mao, the real boss, Ozawa Ichiro nodded solemnly , and immediately turned over and took a palm-sized motor from the workbench, and brought it to Cao Mao: "Mr. Cao, this is one of the key components of the 'Houlang' pro upgrade kit, a brushless DC motor with permanent magnets! "

"The motor is very common. Even if we Fengmao can't do it, we can also purchase other manufacturers. Isn't Japan very good in this regard?"

Mr. Cao Mao looked at Ichiro Ozawa with a little expectation and a lot of confusion in his eyes, but Ichiro Ozawa shook his head helplessly: "Even in Japan, there are only one or two top manufacturers of this kind of motor. It can only be manufactured, and the output is not large. The most important thing is that even if this kind of motor is produced, it will not be used in the most common sports equipment.

It is usually used for launch vehicles, fighter jets, civil aviation airliners, and at worst high-end precision manufacturing equipment, so...Mr. Cao, with all due respect, you should give up the idea of ​​imitation, after all, one of the materials inside is too rare , whether you buy finished products or self-processing is not cost-effective! "

When Cao Mao heard this, his heart skipped a beat: "What kind of material is that?"

"Rare earth permanent magnet!" Ozawa Ichiro looked at the motor in his hand and sighed: "And it is the most expensive rare earth cobalt permanent magnet in this category!"

Cao Mao and others were confused after hearing what Ozawa Ichiro said.

They are a sports equipment company. They are very clear about stainless steel and aluminum alloys. They really don't understand what rare earth permanent magnets are.

No way, Ichiro Ozawa has to popularize science again.

In fact, the rare earth permanent magnet is a kind of permanent magnet material. Compared with the traditional permanent magnet, the magnetic force of the rare earth permanent magnet will not disappear, so it can make the motor have a longer service life and a smaller volume.

Because of this, rare earth permanent magnets have been widely used in aviation, aerospace, precision machinery and semiconductor fields.

It’s just that the output of rare earth permanent magnets is too rare. As of 1984, the output of rare earth permanent magnets accounted for only 13.8% of the total output of permanent magnets, and the most stable rare earth cobalt permanent magnets accounted for less than 2%. .

Therefore, this kind of rare earth cobalt permanent magnet is basically monopolized by developed countries, so that it can lead the world in aerospace, precision manufacturing and other fields.

"This kind of rare earth cobalt permanent magnet material is basically monopolized by several manufacturers in the United States at present, and basically only supplies high-end manufacturers in the United States. We can get a small part in Japan, but they can only be used within the scope set by American manufacturers. ..."

After some popular science, Ichiro Ozawa looked at the motor in his hand that was not as big as a palm and shook his head with a wry smile: "So, in Japan, we don't dare to waste such a good thing on a piece of sports equipment. And the dosage is so large…”

Speaking of this, Ichiro Ozawa sighed again: "It can only mean that the manufacturers who produce this thing have a lot of rare earth permanent magnets in their hands, and they don't care about such a waste at all, so Mr. Cao, you should think about other ways!"

"Can't it be replaced by other motors?" Cao Mao's face was ugly, but he still insisted stubbornly.

"It's not irreplaceable, but you need to double the overall size of your hydrofoil surfboard. Only in this way can you ensure that a motor the size of a kettle can be placed in the transmission compartment below.

Because the traditional permanent magnet materials, whether it is AlNiCo permanent magnet or ferrite permanent magnet, cannot reduce the volume to a satisfactory level. The residual magnetic flux density of the body permanent magnet is low, so the service life of the motor made by the two is very unsatisfactory. In addition, the structure cannot get rid of the collector ring and the brush, and the structural weight cannot be reduced.

If you really adopt this alternative plan, the overall structure of the Fengmao hydrofoil surfboard must exceed 100 kg. By then, will your hydrofoil surfboard be water sports equipment or a small yacht? "

"Would it be so heavy to replace the motor?" Cao Mao was puzzled, but Ozawa Ichiro smiled bitterly: "It's not just the motor, but also the battery!"
