What an electric fan needs is a motor.

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

Although this stuff sounds amazing, in fact, it is only at the level of junior high and high school physics.

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

Not to mention an experienced person like Chu Tianshu, who used to help old men and old ladies repair common furniture such as electric fans and washing machines when he went to the countryside.

It is a little difficult for Chu Tianshu at this time to produce a qualified motor that can maintain a high speed and ensure that the circuit does not burn.

Because many small devices need to be done by themselves.

But if you just debug a motor with a not too high speed, it will definitely not be difficult at all.

After drawing the blueprints and calculating the relevant data, Chu Tianshu called old man Liu, the guard in the factory, to find some smarter workers, and called back all the cooks in the factory.

Although the factory is currently unable to resume work due to the assassination of King Chen, the trial production of a few electric fans does not require many manpower.

Seeing that Chu Tianshu was willing to call Xiao Gong back, old man Liu was also very grateful: "Chu Gong is really kind-hearted."

"I'm not a good person." Chu Tianshu shook his head: "You go back, if there is anything to do, I'll call these little workers to help me."

"it is good."

With his hands behind his back and his waist bent, Old Man Liu went back to the guard room.

What was left were a few small workers that old man Liu called to help Chu Tianshu.

There are four Xiaogongs in total, and one in the middle recognizes Chu Tianshu.

She greeted Chu Tianshu cautiously: "Chu Gong."

"It's you." Chu Tianshu patted her on the head: "Are you still working these days?"

"Well, do some daily closing."

"What are you doing?"

"The washing work of the tailor's shop." Xiaogong said.

Hearing this, Chu Tianshu glanced at her hand.

Those small palms were completely swollen with blisters, and the skin was wrinkled and white.

"How much does the tailor pay?"

"One cent and eight cents a day."

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

"vanilla."

"Last name?"

"Surname Chen, Chen Xiangcao."

"Where are you three?"

Chu Tianshu took a look, and found that most of the remaining three workers were the same as Chen Xiangcao. Their palms were soaked in water for a long time, and they were swollen, white and wrinkled.

My heart skipped a beat: "The four of you worked together in a tailor shop before?"

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

"My name is Wang Chengzi."

"My name is Zhou Congee."

Of the four small workers, three of them are girls.

"You work together, there are many girls." Chu Tianshu called four small workers to come over and help him work.

It is said to be work, but it is actually work such as holding the rotor and winding the coil. It does not require much strength and does not do much work.

Most of the time, the four workers squatted in front of Chu Tianshu with their chins on their hands, watching him work.

"There are a lot of girls." Wang Chengzi watched Chu Tianshu's movements curiously: "Mr. Chu, these jobs are so strange."

"Do you have a distribution center?" Chu Tianshu fixed the coil, compared the number of turns, fixed the brushes, and then started to screw the screws.

Some materials are missing, but it doesn’t matter. It’s the first time to make an AC motor by hand, and apply it to an actual electric fan. The probability of normal use is not high, and it doesn’t matter if it fails.

"Distribution center?" Zhou Porridge didn't quite understand: "What is that?"

"I mean, do you usually gather together when you're waiting for work?"

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

"Will there be regular people who go to the place where you gather and wait for work to send you work?"

"There will be." Wang Huogou nodded.

"I usually do small jobs, how much work can I get three cents a day?"

"Not much." The four children said in unison.

"This kind of work is often tiring?"

"Yeah." Chen Xiangcao nodded.

"What about at home?" Chu Tianshu carefully connected the wires.

The motor can turn normally.

Once the electricity was turned on, the coil in the magnetic field started to rotate, causing a harsh noise.

It is normal for the motor to run normally.

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

The four small workers stared at the motor with wide eyes.

The rotor was spinning, Wang Huogou licked his lips, swallowed a mouthful of saliva, and stretched out his hand to touch the spinning rotor.

Chu Tianshu grabbed him, tugged at the back of his neck, and dragged him aside: "Don't touch it, it's still a little dangerous."

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

At this moment, the four workers no longer remembered the question Chu Tianshu asked them.

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

"Yes." Chen Xiangcao was the first to recover and answered Chu Tianshu: "My parents, mother and brother are all working to make money."

"The whole family is working." Chu Tianshu nodded: "After earning money, life will be better, right? Where do you live?"

"Live in Ping'an Village." Chen Xiangcao thought for a while: "Life is very good, you can eat very full almost every day."

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

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

"Very good." Chu Tianshu nodded: "What about you? Do you like spicy food or sweet food? Fish and shrimp or pork or dog meat?"

"I like to eat fish!" Wang Huogou said, "I like to eat fish! Fish is the best in the world, nothing can compare to it!"

Zhou Congee was at a loss: "I've never eaten fish, can fish taste as good as pork?"

"Fish is much tastier than pork!" Wang Huogou replied immediately, "You have never eaten fish, it tastes delicious, and the meat is in strands. If you eat fish, you have to be careful of the small thorns in the meat." , teething."

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

As he spoke, he couldn't help swallowing his saliva.

Chu Tianshu smiled, and patted him on the head: "Our factory provides beef offal, sheep offal, pig offal, and fire dog offal. When it's time for dinner, you can try it and see if it compares with yours. Which one of the fish you've eaten is more delicious?"

Looking at the pocket watch, the motor has been running for half an hour and there is no problem.

Good.

It's just that the speed is not high.

If you install the fan blades, it will only be slower.

I can install it in the afternoon to see if it works.
