Rebirth 08: Equipment God

Chapter 404 A Roar of 15,000 Turns (Bonus Chapter 1 to Pay Off Debt)

Only after the work was finished did the panic begin to surface.

Just like taking an exam, when you're busy doing the questions, you don't have time to think. Only after you've finished the questions do you start to wonder if you made a big mistake.

At this moment, the head coach Zhai Da stepped forward, clapped his hands and said, "Don't panic, everyone. This is only our first time developing this. Who can produce a prototype so easily? Even if it explodes today, we can collect data and make improvements."

The only one who was truly unperturbed was Zhai Da, because he had already used the [Pure Gold Secret Staff] and telekinesis to understand every detail of the prototype. If there were still any problems, he would be completely unfazed.

That's a big problem.

This means the problem is fundamentally flawed!

Zhai Da walked to the laboratory power supply, which could provide a maximum of 1500V DC power. Although it wasn't long enough, the prototype didn't need such a high voltage.

Looking at his watch, Zhai Da said, "I've done everything I needed to do, just this last bit of work. Let's finish this quickly and go to sleep."

The crowd nodded hesitantly, like students about to hand in their papers, always hoping to delay as long as possible.

However, when Zhai Da placed his hand on the power switch, he suddenly withdrew it and said to everyone, "Let's make it a little more ceremonial, everyone press the start button together!"

Apart from Cheng Mo, who was sitting in front of the computer, Xu Xuejun had no interest in joining in the fun. Everyone else gathered together, each holding up one finger.

The button wasn't large; it wasn't the kind used for rocket launches, but rather an ordinary square switch. Yet, at this moment, it carried the hopes of many young talents.

Zhai Da shouted loudly, "Countdown: 10, 9!"

Everyone joined in the countdown, their eyes filled with growing anticipation.

"87"

"65"

Just as the countdown reached "3", Zhai Da suddenly shouted, "Just kidding! This spot is the most dangerous! Even if it explodes, you won't be able to escape!"

Then, amidst the shock and disbelief of everyone, he firmly pressed the button.

At first, the power supply emitted a slight hum.

A surge of powerful electricity flowed into the cable, and the transient electromagnetic force caused it to shudder, as if one could actually see the energy surging within it.

Cheng Mo immediately said in a deep voice: "Power on, input voltage 400V."

"The silicon carbide MOSFET is operating normally, and the inverter output voltage is 1010V."

"FOC loading successful, sensor data feedback begins."

The equipment was running very fast, far exceeding Cheng Mo's speaking speed, but he still insisted on broadcasting the changes one by one so that everyone could perceive them.

"Gate drive activated, PWM modulator working normally."

"Rotor step acceleration complete, reaching the set target of 15000 revolutions, +82, in 242 milliseconds!"

"Power 349KW, frequency 80.1kHz, stable!"

Inside the laboratory, the only sound was the hum of the motors running, its unique timbre like the arrival of a spaceship in a science fiction movie.

But that was actually the roar generated by 15,000 revolutions!
The startup went exceptionally smoothly, but it wasn't time to pop the champagne yet! Everyone remained tense, staring intently at the prototype.

A motor won't just work for this short period of time. Even if it's not a reliability test of thousands of hours, it still takes some time before it can be considered a success.

Cheng Mo's eyes scanned the various readings on the screen. Most of them were changing rapidly, but as long as there were no major fluctuations, he didn't dwell on them and instead focused on another important issue.

"The silicon carbide device is detected to be heating up at a rate of 3.9°C per second, reaching the set temperature of 80°C. The cooling system is now activated."

"The temperature has reached 120°C and is still rising."

"150°, and it's still rising."

The series of new developments made Zhou Mo's heart tighten: "Is there a problem with the cooling system?"

Chemistry genius Sun Ting, however, remained calm: "Our silicon carbide devices can withstand temperatures above 200°C, but the ideal junction temperature is still around 150°C."

Sure enough, Cheng Mo breathed a sigh of relief and said, "The temperature has stabilized at 162°, so there shouldn't be any problems."

For all continuously operating equipment, temperature is a critical critical factor for survival. Equipment whose temperature cannot be controlled is like a person who cannot control their bladder or bowels—completely useless.

Fortunately, although it exceeded the initial expectations, it was far from reaching the theoretical limit.

Now, the laboratory was completely silent, except for the sound of motors that resembled the landing of a spaceship.

There was no further news for a while.

Qi Lin tilted his head: "The noise is still a bit loud."

Sun Ting stroked her chin: "It feels like the temperature is rising a bit too quickly. Is it because the device's thermal effect is too high, or is the cooling system inadequate?"

Xu Xuejun, with his hands behind his back, said, "I feel a slight wobble in the connector. We can consider optimizing it."

Ge Qiaoqiao rubbed her stomach: "I feel a little hungry."

Everyone waited anxiously, with nothing else to do but watch.

Only Zhai Da, through telekinesis, sensed the violent operation inside the motor—a direct feedback that no human engineer could obtain. He believed this would help him further improve himself. Five minutes passed, ten minutes passed, fifteen minutes passed.

Cheng Mo suddenly said, "Everyone, we're in big trouble."

"What trouble?"

"There's not enough electricity."

Zhai Da turned to look at the laboratory power supply behind him, and sure enough, the power level had dropped to 12%. His face darkened.

Damn it! It shouldn't have been this fast. I got ripped off during the procurement process; this is false labeling!
All I could do was order, "Prepare to shut down the power, otherwise the voltage input will become unstable."

Cheng Mo controlled the motor to gradually slow down and stop via electronic control, and Zhai Da also turned off the power to the laboratory.

After a long while, the laboratory fell silent.

Zhai Da quietly checked the manufacturer of the laboratory power supply and wrote it down in his notebook.

I'll remember this grudge.
When he turned around, he realized that everyone was staring at him without saying a word.

"Wow, that startled me! No wonder it was so quiet."

Sun Ting, hands behind her back, asked, "What did the president say?"

Qi Lin bit her lip, awaiting the verdict.

Cheng Mo's hands were rapidly typing on the keyboard, but his eyes kept glancing over out of the corner of his eye.

Everyone was waiting for Zhai Da's answer.

Zhai Da took a deep breath.

He put on his biggest smile:

"Congratulations, everyone! The prototype silicon carbide motor has been successfully developed!!"

"yeah!!!!"

"finished!"

"Awesome! We did it!"

"π! Unrivaled under heaven!"

------

In a private room at the General Hospital of the People's Liberation Army in northern Beijing, an elderly man with a ruddy complexion is reviewing documents.

Since waking up, he felt that he had much more energy than before, and was therefore more willing to consume more information.

What I have in my hand is a cutting-edge paper on photovoltaic technology.

Although I haven't systematically been exposed to cutting-edge technologies for many years, this content poses no obstacle whatsoever to the giant who dominates an era; in fact, it can be described as simple and easy to understand.

Just then, the ward door was knocked open, and the nurse complained, "Grandpa Qian, if you don't sleep soon, I'm going to tell the doctor!"

Old Qian turned his head and said innocently, "What can I do if I can't sleep? I've been lying here empty-handed for an hour already."

"That won't work either. You should close your eyes and rest. You're having major surgery tomorrow!"

Old Qian shook his head: "That's precisely why I don't want to waste even an hour. Perhaps this is my last."

Just as he was about to say something more, the cell phone that Zhai Da had given him rang. Old Qian raised his reading glasses, held the phone to his eyes, and unlocked it to open the MMS.

It's a photo.

Seven or eight young people gathered together and took a group photo with a piece of industrial-style equipment in the center from an overhead perspective.

Each person held a black card in their hand. Although the details were not clear, it was obvious that they shared the same identity and had a great sense of pride.

Oh. In the corner, there's an older "young man" holding up a card, but he looks completely uninterested.

The photo was accompanied by the following text:

"Teacher, the prototype has been successfully developed. It has a power density of 15000 rpm, 80 kHz, and 350 kW, which is 4 times that of traditional motors. The maximum speed is 5 times that of traditional motors, and energy loss is reduced by 60%. The silicon carbide devices and motor structure are all self-developed."

As Mr. Qian looked at those smiling, youthful faces, a smile unconsciously crept onto his own lips.

The slight unease I felt before the surgery has vanished.

There's nothing to worry about anymore; just hold your head high and set off again.

Mr. Qian, somewhat clumsily operating his phone, sent a brief message to Zhai Da, who was unaware that he was about to undergo surgery: "Congratulations."

Then he reached out and turned off the light.

Waiting for dawn, and waiting for tomorrow!

　This time it's half an hour earlier, and there's an extra update. More adjustments needed!
