From knock-off old-man's electric vehicles to industrial giant

Chapter 24 Self-developed motor rolls off the production line
"tell me the story."

Zhou Tao squinted slightly.

He himself is not highly educated, but he made his fortune early, and many of the company's successful development strategies were formulated by the vice president, his strategist.

"Since Porsche doesn't intend to pursue this aspect and doesn't care about this small market, then whatever Mingxingchen Automotive can do, we can do too..."

"We can also create custom molds for Porsche's exterior for our new car. We can do an equally good job with the exterior design, and combined with the brand's advantages, consumers will have more choices."

I came up with this idea.

Liu Bin himself felt quite pleased with himself.

damn it--

I'm such a genius!

So what if it's plagiarism?

There's nothing shameful about this in business.

Moreover, there are successful precedents.

As established companies in the microcar industry, they should learn from this successful experience, summarize it in new ways, and then use their larger scale and richer industry experience to defeat small, newly established companies like Xingchen!

……

……

Star Headquarters.

The R&D department has been very busy lately.

The main change was the establishment of a new motor and electronic control department, which quickly integrated a new group of R&D personnel into the large team.

Also.

Under Xu Yi's leadership, the human resources department poached a technical director for three major electrical components at a high price last month.

Sun Pengfei was previously a research and development engineer at Huichuan, where he mainly led projects on the development and application of general-purpose servo motors and industrial permanent magnet synchronous motors.

His reason for leaving was simple.

First, the pay wasn't enough; second, Huichuan's overtime work was notoriously demanding in Suzhou Industrial Park, requiring employees to work overtime every day.

Another issue is that large companies have many talented people, and his technical ambitions cannot be realized. His previously designed 36-slot 8-pole motor was only used in a low-power model, which made him so angry that he couldn't sleep well for several days.

But there is nothing to do.

To be fair, his skills and industry experience are indeed quite good, but he's not among the top tier. In a highly competitive environment, he won't stand out.

In the past two years, with the development of the new energy vehicle industry, interdisciplinary fields involving the three core components of electric vehicles have seen a significant increase in the industry premium for talent.

Some top-tier senior professionals have been poached by offers that are almost double the salary.

With industry precedents, he also had the idea of ​​developing in this direction and changing his career path.

Originally, I wanted to look at newly established large new energy vehicle companies, or traditional big manufacturers like Geely and BYD in China. However, after a month of applying to various companies, the relevant conditions have not yet been agreed upon.

During that time, an unexpected incident occurred.

My mother, who lives in my hometown, has suddenly fallen seriously ill and needs to undergo heart bypass surgery. Someone at home needs to take care of her.

no way.

He had no choice but to return to Luzhou, where he planned to find a job temporarily to take care of his family.

I didn't have high expectations and planned to work there for about a year as a transition, but then a headhunter contacted me and I got in touch with Xingchen Technology. I heard that the boss was planning to invest a lot of money to enter the new energy vehicle manufacturing industry. Although he was currently making electric vehicles for the elderly, the future was limitless.

The offer was a base annual salary of 400,000 yuan, plus project bonuses and year-end bonuses, which was definitely more than what he had earned at Huichuan.

Faced with such a statement, Sun Pengfei didn't think much of it. He didn't care at all about the future development of this old man's car company. His only request was to receive an advance of six months' salary to alleviate the pressure on his family to pay for surgery and medical treatment.

in fact.

This request is a bit excessive. Even in traditional large companies, applying for an advance on salary is very troublesome.

Moreover, it will most likely require collateral, and Sun Pengfei is already prepared to apply for a bank loan.

Unexpectedly, the company's CEO only met with him once, had a detailed discussion, and then signed a long-term contract, which he readily agreed to. Once he officially started working, the projects were incredibly easy.

It was solely for the purpose of developing an industrial permanent magnet motor for use in microcars.

I received a six-month salary advance, which solved my immediate problem.

Sun Pengfei harbored a sense of loyalty and duty, a willingness to sacrifice himself for his country.

While it wasn't quite that exaggerated, it did increase my positive feelings towards the company and its CEO, Xu Yi.

Therefore, they spared no effort in developing motor and electronic control systems.

The self-developed motor, which was originally expected to take several months to develop, is now almost complete in just over a month.

This is mainly because Sun Pengfei also applied some of his previous research and development achievements within Huichuan that he had not yet used.

……

"Mr. Xu, in another half month, we can officially start pre-production of our internally developed V1 motor."

The sample being tested is now in the final inspection stage; you can take a look at it first.

In this generation of motors, following the original internal R&D plan, I made a rotor chamfering design, optimized the dq axis inductance ratio, and reduced high-frequency eddy current losses by 30%.

The internal components use neodymium iron boron, and the shell is made of ADC12 die-cast aluminum, which improves performance and heat dissipation efficiency compared to the original design.

The final peak power consumption can reach 5kW, but based on our current vehicle weight and operating conditions, it is sufficient to push the vehicle speed to 110km/h. After internal speed limiting, the power is locked at 3kW. At the rated vehicle speed of 80km/h, the power consumption is reduced by 30% year-on-year.

Of course, this is mainly an optimization of the electronic control and compressor. The motor itself is already very efficient, but the compressor's start-stop and internal electronic control are too crude. I optimized the electronic control strategy and some overheating circuits. After the overall optimization, the range can be increased by 20 kilometers without changing the cost.

The production cost of the first-generation self-developed motor, based on current sales volume estimates, can be reduced by at least 15% compared to purchasing it from external suppliers.

meeting room.

Sun Pengfei introduced the parameters of the internally developed motor to the crowd.

Ultimately, it's still based on a tricycle motor, but by applying the optimization scheme of new energy vehicle motors and further optimizing material costs, the results have exceeded expectations.

"Great, with reduced costs, the range can be increased by 20 kilometers. This is definitely more for the same price, which will make us more competitive offline."

Xu Yi revealed a slight smile.

Even without research, battery life has always been one of the most important factors for consumers.

Even ten years from now, people will still feel anxious about battery life and vehicle range.

The "Star 01" originally had a rated range of 80 kilometers, which was already an excellent standard.

However, if the motor is replaced and the electronic control is optimized, it can reach 100 kilometers, which is quite an extreme product.

After all, the costs are there.

"Another point is that the power output of the self-developed motor is more linear after optimization, and the noise is also much lower," Sun Pengfei added.

This can be considered an optimization at the level of user experience details.

He did it casually while he was researching and designing it.

"We will expedite the production of our self-developed motors so that our two models can be launched as updated versions."

It's only been on the market for a little over four months, and there's already an iteration.

It sounds exaggerated.

But in Xu Yi's view, they have truly created their own product, optimizing the overall vehicle experience through self-developed motors and a redesigned three-electric structure.

This is what is known as "core competitiveness".

Although they look the same.

However, once consumers experience it, they will find that the noise level, power response and linear feedback, as well as the steering feel, are significantly different from other similar models.

Instead of haphazardly piecing together products from the supply chain like other manufacturers.
