After Liu Chi pressed the switch, he turned his gaze to the display of the balance instrument next to him.
0.5 grams!
Well......
Liu Chi scratched his head, it seemed a bit far from the target.
If you want to achieve 1UM, the spindle is only allowed to have a maximum of 0.2 grams of residual unbalance. Liu Chi looked at the motor that was still working for a long time, and then glanced at the value that was motionless like an old stubborn man.
It seems that this is caused by the unbalanced centrifugal force of the rotating body.
I don't know if it's a magnetic field problem or an unbalanced rotor mass. I'll have to test it slowly to find out.
It doesn’t matter. As long as the path is right, we can improve it slowly.
If you want to get it right the first time, that's basically impossible.
If the pressure generated by the bearings is the same, then the problem lies in the rotating body, which is balanced. However, when the rotating body rotates at high speed, the centrifugal force should be uniform...
Liu Chi touched his chin for a long time:
Is it a material problem? Is it causing uneven force?
Uneven material, or errors in blanks, processing and assembly make it impossible for the centrifugal inertia forces generated by each tiny particle on the rotating body to offset each other when it rotates.
That would result in obvious errors.
It may even cause vibration, generate noise, accelerate bearing wear and shorten mechanical life.
......
Five minutes later, Liu Chi turned off the motor switch, and after the motor stopped working, he disassembled the motor and took out the rotor.
Now that it works properly, let's test it one by one.
Find the problem and then modify it slowly.
There's no rush anyway.
Rotor balancing:
Liu Chi turned on the balancer SE008, put the rotor on it, and started...
Error 0.95!
It was 0.5 grams just now!
If the error is 0.95, it should be 0.3 grams! That means the force field in the stator is not uniform, and a residual force of 0.2 grams is added to the rotor.
......
At around five in the afternoon, Ye Yuxin saw Liu Chi stop his work and interrupted him: "Idiot, it's time to eat."
"Let's eat." Liu Chi replied honestly and checked the time.
Oh my god!
In the blink of an eye, half a day passed.
It seems like he doesn't do any work.
well! ! !
Time flies so fast, it passes in the blink of an eye.
"It's almost six o'clock. If it's not healed, we'll continue tomorrow."
"Okay." Liu Chi glanced at the pile of equipment on the workbench. It seemed that it would take a while to finish it. He decided to continue tomorrow and simply organized the equipment.
Clean up what needs to be cleaned up, save what needs to be saved.
Turn off the instrument.
Follow Ye Yuxin out of the laboratory.
go home!
"parking!!!"
Just after leaving the industrial park and passing a small path, Liu Chi suddenly spoke.
'Squeak...' The car stopped steadily.
"What's wrong with Liu Chi?" Ye Yuxin was startled.
"It's okay." Liu Chi waved his hand, looking at the beautiful figure outside the window, his eyes twitching uncontrollably.
Zhou Meng looked at the lowered glass window, walked a few steps forward, walked to the car door, glanced at Liu Chi in the window, blinked, waved his hand, and said with a little pride: "Brother Chi."
Written on his face: Surprised or not? Unexpected or not.
Upon hearing this, Ye Yuxin leaned forward curiously.
A slim girl about 1.65 meters tall, wearing a white coat and a black hat, appeared in Ye Yuxin's sight.
The jet-black hair covered half of her face and fell directly in front of her chest.
The four words (Elf Girl) jumped into Ye Yuxin’s mind.
"Sure, now you know how to surprise me. I think you deserve a beating." Liu Chi came to his senses after a few seconds and glared at the girl: "Get in the car."
"Hehe." Zhou Meng made a face and finally sat in the passenger seat obediently.
"Where's the luggage?"
"Chiba Hotel, not far from Huaqing." Zhou Meng fastened his seat belt obediently this time.
"Chen Fei, let's go to Qianye Hotel first." Liu Chi said to Chen Fei who was driving.
"......"
"Wife, let me introduce you to Zhou Meng, my half-disciple, a 'big shot' who just returned from Xbridge University in Europe." Liu Chi introduced Ye Yuxin, who had been silent, and emphasized the word "big shot" when he said it.
"Call me sister-in-law." He added three words to Zhou Meng.
"Hello, sister-in-law, you are so beautiful." Zhou Meng turned around and looked at Ye Yuxin enviously.
"Hello." Ye Yuxin nodded with a smile.
"What's wrong? You didn't even say hello when you came back? Can you change your personality? If something happens, how am I going to explain it to your parents?"
"This is my true nature." Zhou Meng retorted unconvincedly: "Besides, China is not Africa, what's there to be afraid of? Can anyone sell me out?"
"With your bad temper, you might not be able to find a boyfriend."
"Who knows? Although I don't have one now, there will be someone waiting for me in the future, waiting for me to meet him one day." Zhou Meng said proudly, with a look on her face saying: Heart, heart...
"King Yama." Liu Chi swung his knife in return.
"Pfft..." Ye Yuxin beside her couldn't help but burst into laughter.
"Damn Liu Chi, damn Liu Chi, you bully me." Zhou Meng was furious. If he hadn't been tied up with a safety belt, he would have rushed over. Seeing Ye Yuxin next to him, he said, "Sister-in-law, look, this guy is bullying me again."
"Liu Chi, you don't even know how to give in to sister Zhou Meng." Ye Yuxin now liked this straightforward little sister a little bit.
