What an electric fan needs is a motor.

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

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

Even the average person who is not familiar with the relevant theorems can slowly come up with a simple usable device model with the vague words "cutting magnetic lines", "stator" and "rotor".

Not to mention Chu Tianshu, an experienced person who once helped the old man and old lady repair common furniture such as electric fans and washing machines when he went to the countryside.

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

Because a lot of small equipment needs to be done all over again.

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

After drawing the drawings and calculating the relevant data, Chu Tianshu called the doorman Liu to find a few clever workers, and called all the cooks in the factory back.

Although the factory is currently unable to resume work because of the assassination of Chen Wang, the trial production of a few electric fans requires not many manpower.

Old man Liu was also very grateful when he saw that Chu Tianshu was willing to call Xiaogong back: "Chu Gong is really kind-hearted. ”

"I'm not a good person." Chu Tianshu shook his head: "You go back, if there is anything, I will call these small workers to do it." ”

"Okay."

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

The rest were a few small workers that Old Man Liu called to help Chu Tianshu.

There are four small workers, and there is one in the middle, who knows Chu Tianshu.

She greeted Chu Tianshu solemnly: "Chu Gong." ”

"It's you." Chu Tianshu patted her head: "Are you also working these days?" ”

"Well, do some daily settlement."

"What are you doing?"

"The laundry work of the tailor's shop." Xiao Gong said.

Chu Tianshu glanced at her hand when he heard this.

The small palms were completely swollen by the blisters at this time, and the skin was wrinkled and white.

"How much does the tailor shop?"

"One cent, eight cents a day."

"It's ruthless." Chu Tianshu pursed his lips: "What's your name?" ”

"Vanilla."

"What's the last name?"

"The surname is Chen, Chen Vanilla."

"What about you?"

Chu Tianshu took a look, and most of the remaining three small workers were the same as Chen Vanilla, their palms had been soaked in water for a long time, and they were soaked and swollen, white and wrinkled.

"You four used to work together in a tailor's shop?" ”

"Yes, we're in this 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 are girls.

"You work together, there are a lot of girls." Chu Tianshu beckoned four small workers to come over and help him with his work.

It is said that it is work, but in fact, it is also work such as taking rotors and winding coils, which does not require much effort and does not have much work.

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

"There are a lot of girls." Wang Chengzi looked at Chu Tianshu's movements curiously: "Chu Gong, these jobs are so strange." ”

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

There are some materials missing, but it doesn't matter, the first time to make an AC motor, apply it to the actual electric fan, the probability of being able to use normally is not high, and it doesn't matter if it fails.

"Hub?" Zhou Congee didn't understand well: "What is that?" ”

"I mean, do you all gather together when you wait for your work to be done?"

"yes, yes." Chen Xiangxiang bent down and watched Chu Tianshu assemble the rudimentary motor, her big eyes full of doubts.

"Will there be a fixed number of people who will come to the place where you gather and wait for work to send you work to?"

"Yes." Wang Huogou nodded.

"How much work can I get three cents a day as a small worker?"

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

"This kind of work is often tiring?"

"Uh-huh." Chen Xiangxiang nodded.

"Where's the family?" Chu Tianshu carefully took the wire.

The motor can rotate normally.

As soon as the electricity is applied, the coils in the magnetic field turn dripping, causing a harsh noise.

It's normal for the motor to work properly.

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

The four workers stared at the motor with wide eyes.

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

Chu Tianshu grabbed him, grabbed him by the collar at the back of his neck, and dragged him aside: "Don't reach out and touch it, this thing is still a bit dangerous." ”

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

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

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

"Yes." Chen Xiangxiang was the first to come back to her senses and replied to Chu Tianshu: "My parents, parents and brother are all working to make money. ”

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

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

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

"Like to eat?" Chen Vanilla was in a trance: "I like ...... Likes to eat meat. ”

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

"I love fish!" Wang Huogou said: "I like to eat fish! Fish are the best in the world, nothing can compare to them! ”

Zhou Congee was dazed: "I haven't eaten fish, can fish be as delicious as pork?" ”

"Fish is much better than pork!" Wang Huogou immediately replied: "You haven't eaten fish, that taste, take a bite and smell fragrant, the meat is a lock of meat, you have to be careful of the small thorns in the meat when you eat fish, and prick your teeth." ”

"But remove the little thorns, hehe, fish is the best thing in the world!"

As he spoke, he couldn't help but swallow.

Chu Tianshu smiled and patted his head: "Our factory provides beef offal, haggis, pig water, and fire dog water to eat, and when it comes to the meal, you can taste it and see which one is better than the fish you have eaten." ”

Looking at the pocket watch, the motor has been spinning for half an hour without any problems.

Very good.

It's just that the speed is not high.

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

In the afternoon, you can put it on and see if it can be used.
