What the electric fan needs is a motor.

In a common sense, it is to convert electrical energy into mechanical energy.

Although this thing sounds amazing, it is actually the level of physics in junior high school and high school.

Even ordinary people who are not very familiar with relevant theorems can slowly introduce a simple usable device model with the vague words "cutting magnetic lines", "stator" and "rotor".

Not to mention Chu Tianshu, who used to help old men and women repair common furniture such as electric fans and washing machines when they went to the countryside.

It is a bit difficult for Chu Tianshu to produce a qualified motor that can maintain high speeds and ensure that the circuit does not burn.

Because many small devices need to be done again.

But if you just debug a motor with a low speed, it will definitely not be difficult.

After drawing the drawings and calculating the relevant data, Chu Tianshu called the factory guard Old Man Liu to find a few smart workers, and called back the factory chefs.

Although the factory cannot resume work due to the assassination of King Chen, the trial production of several electric fans actually requires not much staff.

When Old Man Liu saw Chu Tianshu willing to call the tiny worker back, he was very grateful: "Mr. Chu is really kind-hearted."

"I'm not a good person." Chu Tianshu shook his head: "You go back. If you have any questions, I will call these little workers to do it."

"good."

Old Man Liu carried his hands on his back, hunched his back, and went back to the guard room.

What remains are the few workers who Old Man Liu called to help Chu Tianshu.

There are four small workers in total, one in the middle, who recognizes Chu Tianshu.

She greeted Chu Tianshu with restraint: "Mr. Chu."

"It's you." Chu Tianshu patted her head: "Have you been working these days?"

"Yeah, make some daily break."

"What day break are you doing?"

"The washing work of the tailor shop." said the worker.

Chu Tianshu glanced at her hand when he heard this.

The small palms were soaked in water that they were completely swollen, their skin wrinkled and turned white.

"How much does a tailor shop pay?"

"One cent to eight cents a day."

"It's so cruel." Chu Tianshu curled his lips: "What's your name?"

"vanilla."

"What's your last name?"

"The surname is Chen, Chen Xiangcao."

"Where are you three?"

Chu Tianshu looked at it and found that most of the remaining three workers were like Chen Xiangcao. The palms were soaked in water for a long time, soaked in soaking, and their hair was wrinkled.

My heart moved: "You four were working together in the tailor shop?"

"Yes, we are together." A boy nodded: "If you go back to Chu Gong, my name is Wang Huogou."

"My name is Wang Chengzi."

"My name is Zhou Zhu."

There are four small workers, three of them are girls.

"There are many girls who work together." Chu Tianshu invited four young workers to come and help him with his work.

It is said that it is working, but in fact, it is just a job like holding a rotor and winding a coil. It doesn’t take much effort and doesn’t have much work.

Most of the time, four young workers squatted in front of Chu Tianshu with their cheeks and watched him work.

"There are many girls." Wang Chengzi looked at Chu Tianshu's actions curiously: "Mr. Chu, these jobs are so strange."

"What distribution center do you have?" Chu Tianshu turned around the coil, compared the number of turns, fixed the brush, and then started to screw the screws.

Some materials are missing, but it doesn't matter. The first time I use it by hand-made AC motor, it is not very likely to be used normally in the actual electric fan, and it doesn't matter if it fails.

"Distribution Center?" Zhou Zheng couldn't quite understand: "What is that?"

"I mean, do you always gather together when you wait for work?"

"Yes, yes." Chen Xiangcao bent over and watched Chu Tianshu assembled the simple motor, her big eyes full of doubts.

"Why will a fixed person come over to where you gather and wait for work to assign work to you?"

"There will be." Wang Huogou nodded.

"How much can I get a job that I usually work as a small job, but I can get three cents a day?"

"Not many." The four children spoke in unison.

"This kind of work is often very tiring?"

"Yeah." Chen Xiangcao nodded.

"Where is at home?" Chu Tianshu carefully connected the wire.

The motor can rotate normally.

Once the electricity is turned on, the coils in the magnetic field are turning, causing a harsh noise.

It is normal for the motor to operate normally.

Most people make simple motors, but the probability of failure is not high.

The four workers stared at the motor with wide eyes.

The rotor was spinning, Wang Huogou licked his lips, swallowed, and stretched out his hand to touch the rotor that was spinning.

Chu Tianshu grabbed him, grabbed the back of his neck, and pulled him aside: "Don't reach out, this thing is still a bit dangerous."

As he said that, Chu Tianshu sat on the ground and watched the motor run with four small workers.

At this moment, the four small workers no longer remembered the questions Chu Tianshu had asked them.

So Chu Tianshu asked again: "Are there anyone else working in the family besides you?"

"Yes." Chen Xiangcao came back to her senses and answered Chu Tianshu: "My parents and brother are working and making money."

"The whole family is working." Chu Tianshu nodded: "Then after making money, life will be better, right? Where can I live?"

"Living in Ping'an Village." Chen Xiangcao thought for a while: "Life is very good, and I can eat very much almost every day."

Chu Tianshu glanced at her: "What do you like to eat?"

"I like to eat?" Chen Xiangcao was in a daze: "I like...I like to eat meat."

"It's pretty good." Chu Tianshu nodded: "What about you? Do you like spicy food or sweet food? Fish, shrimp, pork, dog meat, etc."

"I like to eat fish!" Wang Huogou said: "I like to eat fish! Fish is the best in the world and can't compare to anything!"

Zhou Zheng was confused: "I have never eaten fish. Can fish taste better than pork?"

"Fish is much better than pork!" Wang Huogou replied immediately: "You have never eaten fish meat. It tastes delicious. The meat is tied up in a slight way. When you eat fish, you have to be careful of the thorns in the meat and thighs."

"But remove the thorns, hehe, fish is the most delicious thing in the world!"

He said, and he couldn't help swallowing.

Chu Tianshu smiled and patted his head: "Our factory provides beef and crumbs, mutton and pigs, and fire dogs. It will be dinner time later, you can try it and see which one is better than the fish you have eaten."

I took a look at the pocket watch and the motor turned for half an hour and there was no problem.

Good.

The speed is not high.

If you install a fan blade, it will only be slower.
