Super industrial overlord

Chapter 134 Zhao Feng's Achievements

"Boss, I'm still not sure how many people are needed for this, just to design and develop all kinds of motors on the machine tool, at least five people in the electric power industry, and 3 to 4 junior and intermediate students in the mechanical industry are needed.

In addition, in terms of junior masters, we need at least one hundred junior masters in the early stage, and some junior masters in the mechanical industry. After all, the electric power industry and the mechanical industry are inseparable.

After the design is finished in the future, whether it is the electric power industry or the mechanical industry, at least a few hundred students are needed. Of course, boss, if you want to design more advanced motors, or cross-generational motors and other things in electricity, For example, batteries, etc., then more Xueba are needed. "Zhao Feng replied Zhang Yi's words.

"Okay, then I will appoint you as the director of the motor R&D department of our Colorful Stone Group, and you can go to the factory to choose a workshop for yourself as a temporary laboratory for your motor R&D department. After the experimental building is completed, go to Moved to the experimental building together with other laboratories."

When Zhang Yi said this, he thought for a while and said. "Wait a minute, I will give you some according to your requirements, elementary and intermediate students, but I hope that you can design and manufacture the motors and servo motors required for compound high-performance machine tools before April next year. No Do you know if you can finish it?"

"Boss is fine. I guarantee that I will be able to design and manufacture all the motors needed for machine tools before April next year. After all, in this regard, your country's foundation is not weak. In fact, what is lacking is the various components in the motor. At the same time, many motor patents have been applied by foreign manufacturers, which has led to the reason why many manufacturers in your country are controlled by others in this regard.

Since I came to this universe, until now, during this period of time, I have learned a lot about the theoretical knowledge of motors and electricity in your universe, and I even disassembled many motors in the factory to study them.

Then combined with my original theoretical knowledge of the universe, my technical level has been greatly improved.

And since this period of time, I have also designed a high-power micro DC high-speed motor.

However, due to the limitation of materials in your universe, especially the bearing materials, generally speaking, your motors rotate at a few thousand revolutions per minute, even if there are a few motors with tens of thousands of revolutions, it is already the limit.

If the speed is too high, the first thing you can't stand is the bearing. Even the high-speed miniature bearings can only turn tens of thousands per minute.

But our Qicaishi is different, because our Qicaishi bearings are very good, even the bearings of ordinary size can easily withstand the speed of tens of thousands of revolutions, if we use the bearing steel made by our Qicaishi to manufacture miniature bearings If it is, then hundreds of thousands of revolutions per minute are easy.

So in the past few months, in addition to maintaining the power safety in the factory, I also designed an ultra-high-speed micro-motor. The micro-motor I designed has a theoretical maximum speed of 12 to 24 volts. It can reach 50 revolutions, but considering materials and other issues, it can easily reach 40 revolutions per minute in practical applications. After finishing speaking, Zhao Feng looked at Zhang Yi expectantly.

"What! You have designed a miniature ultra-high-speed motor, and it can theoretically reach 50 revolutions per minute. I don't know how powerful this motor is, how long it lasts, and how big it is." Zhang After hearing this, Yi immediately asked back.

It's no wonder that Zhang Yi is anxious, after all, the use of micro high-speed motors in modern society is already very extensive.

Micro motors generally refer to motors with a diameter of less than 160 mm, or a rated power of less than 750 watts, or with special performance and special purposes.

Its application fields are very wide, such as food machinery, textile machinery, medical equipment, smart doors and windows, monitor pan/tilt, household appliances, cooling and heating air conditioner fan motors and so on.

Of course, like other mechanical equipment, there are many types of micro motors, but they can be roughly divided into DC motors, AC motors, self-angle motors, progressive motors, rotary transformer motors, shaft encoders, and AC and DC motors. , Tachogenerators, induction synchronous motors, linear motors, voltage motors, motor units, and other special motors 13 categories.

"Boss, the micro motor I developed is a brushless DC micro motor with a permanent magnet structure. The diameter of the motor is 10-30 mm. The maximum speed of 30 mm can theoretically reach 50 per minute, and the theoretical maximum power can reach 3000 watts. , The life of the micro motor is also very long. Theoretically, the trouble-free running time is at least 10 hours. In theory, it cannot be determined in the actual application process.

After all, after I designed and manufactured this motor, it has been less than two months now, and he can't test the mechanical life of the motor at all.

However, the boss's micro motor also has a very big defect, that is, its volume can only be within 10 to 30 mm. If the volume exceeds 30 mm, then even the bearings we made can withstand such a speed, but Other materials on the motor cannot withstand the centrifugal force generated by such a high rotational speed.

Due to the high speed and strong centrifugal force of this motor, the requirements for materials are also particularly high. Therefore, the cost of manufacturing this motor is also relatively high. The cost of materials required to manufacture each motor is more than 20000 yuan. , which is only the cost of materials.

In addition, this motor has very high requirements for the production process. The production of such a micro motor requires a total cost of at least 35000 yuan. "After listening to the translator, Zhao Feng thought for a while before seriously answering.

Of course, Zhang Yi knows about the permanent magnet miniature brushless DC motor. After all, when he was working in Hangzhou, he was engaged in the electric vehicle repair industry, and most of the motors used in electric vehicles are permanent magnet DC motors. Brushless Motor.

At the same time, I also understand the working principle of this motor. The permanent magnet brushless DC motor is a DC motor with one or more magnets to establish a magnetic field. Compared with other DC motors, this motor has small size, high efficiency, and simple structure. With the advantages of less copper, it is the most important type of low-power DC motor.

Most of the permanent magnet brushless DC motors are the same as electric vehicle motors, and the speed is relatively slow, but the permanent magnet DC motor developed by Zhao Feng has such a fast speed that it has overturned Zhang Yi's perception of permanent magnets. Knowledge of brushless DC motors.

But thinking of the manufacturing price of this motor, Zhang Yi felt relieved. Obviously, Zhao Feng must have added a lot of rare earths in the process of developing this motor, otherwise the manufacturing price of this motor must not be so high. Knowing that the manufacturing price of a general electric vehicle motor including raw materials is only 200 yuan, but the price of this motor is so high that the price of raw materials alone is far more than 100 times the price of the motor on an electric vehicle.
