However, the super-hard alloy steel developed by Feng Lin and the others is much stronger than ordinary tungsten alloy. At a high temperature of 1200°C, its performance will not change much, even at 1500°C.

At temperatures, this super-hard alloy steel also has a certain hardness.

You know, at a temperature of 1500℃, if it is ordinary steel, it will have melted, but this super-hard alloy steel can still maintain a very high hardness at 1500℃, and even the internal structure is not

How much change will there be?

After seeing these data, Zhang Yi was very happy, because with these super-hard alloy steels, the various machine tools produced by their group no longer need to go to the market to buy tools produced by other factories.

Originally, Zhang Yi was afraid that their materials laboratory would develop super-hard alloy steel and planned to use bearing steel to replace it. After all, the previous bearing steel had excellent performance and could be used as ordinary props in the airport.

However, if you are processing ordinary steel, the previous bearing steel is enough. However, if you want to process some hard materials, the hardness of the previous bearing steel is not enough, and you must use other props.

For example, diamond tools.

And now with this kind of super-hard alloy steel, the previous glass with properties comparable to diamond, and the high-performance bearing steel developed before, then the various machine tools produced by their Colorful Stone Group can

It comes with three sets of knives. The first set of knives is made of high-performance bearing steel and is mainly used to process relatively common materials, such as aluminum alloy, ordinary steel, etc., while the second set of knives is made of this kind of tool.

Made of super-hard alloy steel, it is mainly used to process materials with relatively high hardness. The last set of tools is used to process materials that cannot be processed by ordinary tools.

Of course, if the material to be processed reaches or exceeds the level of diamond in terms of hardness, then the current Colorful Stone Group has no solution for the time being, and at the current level of earth's technology, there is currently no tool that can process materials with a hardness exceeding diamond.

Currently, the most common methods on earth for processing materials that are harder than diamond are laser cutting and grinding.

Later, Zhang Yi chatted with Feng Ming for a while, and during the chat with him, he also invited the top students in their materials laboratory to go to the third floor of the cafeteria for dinner in the evening.

After walking out of the materials laboratory, Zhang Yi came to the electromechanical laboratory again.

However, just when Zhang Yi walked to the door of the electromechanical laboratory, there was a screaming sound in the laboratory that can only be made when the motor rotates at high speed. According to Zhang Yi's judgment, the speed of the motor that made this sound was

It requires at least 100,000 revolutions to achieve this.

Sure enough, when Zhang Yi walked into the laboratory, he found that Zhao Feng and the others were testing a micro motor, and the size of this motor was obviously much larger than the previous motors in their factory.

At least one hundred millimeters.

It was obvious that Zhao Feng and the others had made new achievements in the electromechanical laboratory. Seeing that Zhao Feng and the others were paying full attention to the motor being tested, they did not notice Zhang Yi's arrival. He did not speak, but walked silently.

Next to Zhao Feng, pay attention to the test data on the side.

As he had guessed before, the speed of this motor was very high at this time, reaching the level of 100,000 per minute, and even so, the speed of this motor was still increasing rapidly. In less than half a minute, the speed of this motor

The speed reached 150,000 rpm.

However, when the speed reached this level, the increase in speed began to slow down, and finally the speed finally stayed at the level of 180,000 per minute, and it seemed that the motor was rotating very smoothly at this time, and there was no abnormality.

After the motor maintained this speed for more than ten minutes, Zhao Feng finally discovered Zhang Yi's presence, so he said, "Boss! When did you come here."

"Not long after I came here, I saw that you were testing this motor, so I didn't bother you. I think this motor is different from the previous two. Is it a new product just completed by your laboratory?" Zhang Yi asked.

"Yes, boss, this motor is a micro motor that has just been successfully developed by our electromechanical laboratory. Compared with the previous micro motors, the size of this motor is much larger, reaching one hundred millimeters. However, due to the material

As well as the increase in motor size, the speed of this motor is much slower than that of the No. 2 motor, and can only be maintained at about 180,000 rpm.

At the same time, due to the increase in motor size, the power and torque of this motor are much larger than the previous two models. Of course, in terms of power consumption, this motor is also several times that of the previous models, reaching

It consumes 11 kilowatts of electricity per hour.

Although this motor is already very good in other aspects of performance, I feel it is still a bit high in terms of power consumption, so we are now looking for ways to reduce the power consumption of this motor!

However, it is not easy to reduce power consumption. It has been nearly a month since we successfully developed this motor. During this period of more than a month, we have thought of many ways.

It is impossible to reduce power consumption to a standard we can bear.

After all, such high power consumption is not suitable for current flying cars at all, unless we develop a larger-capacity battery." Zhao Feng said a little depressed.

"Gong Zhao! Don't be anxious, we still have plenty of time. After all, our Qicaishi Group's manned aircraft production qualifications have not been approved yet, and we don't know when they will be approved.

And even if the production qualifications for manned aircraft are now approved, we will not be able to produce and sell flying cars immediately," Zhang Yi told him.

In fact, Zhang Yi is very satisfied with this motor. After all, its size is only a hundred millimeters, but its power has reached ten kilowatts. This is already an excellent job.

Although this motor cannot be used in flying cars for the time being due to power consumption, such a motor does not necessarily have to be used in flying cars. This motor can be used in many other places. For example, they

on various machine tools, as well as on future products developed based on this motor.

And even if it is to be used on a flying car, the size of the flying car can also be increased to increase the battery capacity of the flying car. After all, the previous flying car was a small flying car, and its maximum take-off weight was only

It only weighs less than 2,000 kilograms, and the battery it carries is of course very limited.

For example, the flying car that the military asked them to develop was very suitable for using this kind of motor to make ducted fans.

If the previous No. 2 motor is used, then due to the size and power of the motor, the number of suspended fans can only be increased. According to Zhang Yi's personal judgment, if the military standards are to be met, the number of suspended fans must be increased at least

More than double, that is to say, the number of floating fans alone is 16.

In this case, the safety of the flying car will be greatly reduced. At the same time, the power consumption will be very large, and it will not be able to achieve the three-hour cruising range required by the military.

If this motor is used to make a ducted fan, then the number of suspended fans on the flying car required by the military can be greatly reduced. Although it is still not possible to determine the specific performance of using this motor to make a ducted fan.

How much thrust can it achieve?

However, one thing that is certain is that the thrust of the channel fans manufactured based on this motor in the future will definitely be much greater than that of the No. 2 motor.

"Gong Zhao, the performance of this motor in terms of power consumption has been reduced to the limit. It will take a huge amount of time to continue to modify it. Even if the power consumption and performance can be reduced, there is not much room for improvement.

I don't think it's better to do this. We don't need to make any modifications to the power consumption of this high-speed motor. To spend such a huge effort to reduce that little bit of power consumption, I think it's better to find a way on the battery.

After all, it is much easier to increase the battery's capacity than to work on the motor. Moreover, once a breakthrough is made in the battery, many of our future products can also be used." Zhang Yi thought for a while, and then continued to talk about it.

Zhao Feng said.

"Boss, I'm over the top. The power consumption of this motor has indeed reached its limit. If you want to reduce the power consumption of this motor, you have to reduce the power of this motor or use a better super

Conductive materials, but we currently don’t have these, so we might as well work on batteries.

You know, we now have a high-performance superconducting material, so it is not difficult to develop high-performance batteries based on this high-performance superconducting material. If we don't get into trouble and just work on the motor, then it is very possible,

We have already developed high-performance batteries, there is no need to wait until now, boss, why didn't you remind me earlier?" After hearing Zhang Yi's words, Zhao Feng suddenly realized, and at the same time, he also complained a little about Zhang Yi not reminding him earlier!

You must know that they had successfully developed this motor more than a month ago. At that time, this motor had higher power and faster speed. The power had reached 12 kilowatts, and the speed could reach up to 185,000 rpm.

But the power consumption is naturally higher.

For more than a month, they have thought of many ways to reduce the power consumption of this motor. Although the current power consumption of the motor is from about 13 kilowatts per hour, it is about 10.5 to 11 kilowatts per hour.

, but the motor speed and motor power are also greatly reduced.

It can be said that in the past month or so, they have actually been doing useless work, which can even be described as regressing. If Zhang Yi could remind him earlier, then he would not have to waste so much time and effort in the past month or so.
