Chapter 96 Servo Motors: The Heart of Machine Tools Leading the Way!

Red Star Technology, Large Conference Room.

Over fifty people were sitting together.

An enamel tea mug was placed in front of everyone.

Through unremitting efforts.

Out of more than 100 SSRs, everyone who could be recruited was here.

Among them was Zhao Qiang, the 'Clumsy Hand' poached from the machine tool factory.

There was Jiang Jun, who had just paid his daughter's hospital bills and shaved his beard clean.

There was Liu Xiaodong, who was lying on the table, boredly spinning a ballpoint pen.

There were also the original team members like General Manager He Zhenhua, Factory Director Lao from the motor factory, Master Niu, Li Jianguo, Big Cannon, and Wang Yu.

Lin Xi sat in the head seat, his gaze sweeping over everyone one by one.

If one could open a heavenly eye at this moment.

They could probably see a purple mist called 'National Fortune' surging above this roof.

This wasn't just a meeting; this was clearly an investiture of gods!

"Quiet down."

Lin Xi tapped on the table.

Although he was incredibly young.

After experiencing the storms of the past few months, he had already cultivated the aura of a leader.

The buzzing in the room vanished instantly.

"First, I'll announce the groups."

"Jiang Jun will be the leader of the Optical-Mechanical Group, responsible for the R&D of grating scales."

"Zhao Qiang will be the leader of the Precision Structure Group, responsible for the bed structure design."

"I will lead the CNC Group myself."

"Old He will coordinate the other parts."

"Sister Liu!" Lin Xi suddenly shouted toward the door.

"Aye! Manager Lin, at your service!" Big Sister Liu, who was in charge of logistics, pushed the door open and entered.

Lin Xi pointed to the crowd.

"The people in this room are all the precious treasures of Red Star."

"From today on, for the food standards, there must be meat every day and plenty of milk!"

"This group uses their brains. If anyone loses weight, I'll dock your performance pay!"

"You got it!"

Big Sister Liu's shout caused a warm current to instantly flow into the originally somewhat restrained and serious atmosphere.

In this era, drawing a big pie wasn't as good as giving big pieces of meat.

But this kind of 'protective' attitude that even cared about their weight was more effective than any mobilization slogan.

After a brief exchange of pleasantries, they got down to business.

"Engineer He, show everyone our motor."

Hearing this, He Zhenhua gently placed a motor on the table.

It was about the size of an ordinary thermos, with a silver-gray metal casing.

The surface had precision-turned cooling fins, and the tail trailed a complex plug.

Compared to other industrial motors, it looked too delicate, even a bit 'effeminate'.

"Is this our stepper motor?"

Someone from the audience asked.

"Manager Lin, this size doesn't seem right, does it?"

"I've seen some imported stepper motors, and they're three times larger than this."

"Can such a small thing drive a ball screw?"

"Don't let it stall as soon as a load is applied."

Industrial common sense in the 80s: big was good, heavy was strong.

"What's the step angle?"

Someone reached out to fiddle with the motor shaft.

"1.8 degrees or 0.9 degrees?"

This was asking about the parameters of a stepper motor.

In this era, CNC machine tools relied entirely on stepper motors to 'count steps' to move.

One step at a time; if you miscounted, it was all over.

He Zhenhua looked up, glanced at Lin Xi, and suddenly smiled.

"This isn't a stepper motor."

"This motor doesn't need to count steps."

"Not a stepper?"

The person was stunned. "Then is it a DC motor?"

"How do you control the precision then?"

"It rotates when powered on, and when powered off, inertia can still carry it half a turn. How do you manage positioning?"

"This isn't open-loop control."

Lin Xi stepped forward, his fingers gently stroking the black cylindrical protrusion at the tail of the motor.

The bullet chats in the streaming room were crazily scrolling across his retina.

[Holy crap! A permanent magnet synchronous servo!]

[The Streamer is going to bomb the fish in the 80s newbie village!]

[This is such a dimensional strike! It's like using a smartphone to smash a brick phone!]

[This structure is the mainstream after 2010, right? It's definitely black technology for that time!]

[These experts are going to doubt their lives, Hahaha!]

Lin Xi smiled.

"This is called a servo motor."

His voice wasn't loud, but it was like a depth charge thrown into a fish pond.

"What's carried on its rear isn't a counterweight; it's an encoder."

"It doesn't need you to tell it how many steps to turn."

"It will provide real-time feedback on where it has turned and how many degrees."

"If it's off, it will pull itself back."

The entire conference room became so quiet that one could hear a pin drop.

Zhao Qiang's mouth hung wide open.

As a mechanical genius, he instantly understood the terrifying nature of this.

A stepper motor is like 'a blind person walking'.

The main controller says to take a few steps, and it takes them. If it slips (loses a step), the main controller has no idea.

But a servo motor is 'running with eyes open', with its own positioning and navigation!

"But... what about the torque?"

Zhao Qiang was a bit skeptical.

"This volume is too small. The magnetic field strength won't be enough; it simply won't have any power!"

"neodymium iron boron."

Lin Xi calmly uttered those three words.

"The third generation of rare earth permanent magnet materials."

He held up three fingers, his tone calm.

"The torque of this motor..."

"Is three times that of similar foreign products!"

Boom!

This time it wasn't just shock; it was practically horror!

The expressions of the people in the audience were a sight to behold.

Except for the original core team, most of the people in the Red Star Laboratory were newcomers with different goals.

Some were there for the technology, some for their families, some to realize their ambitions, and some purely for the good benefits.

Originally, they all had a bit of arrogance.

They felt they were experts who had been begged to come by this 'youngster' Lin Xi.

As a result, before their seats were even warm.

The man had casually thrown out a motor.

The design concept was an era ahead.

The material parameters crushed foreign ones by three times.

At this moment, the arrogance in their hearts was crushed to dust.

Lin Xi looked at everyone's dumbfounded expressions and was satisfied.

This show of strength had achieved its effect.

"Now that we have the heart of the machine tool."

"Next is the brain of the machine tool."

Lin Xi gave Sun Erga a meaningful look.

"You got it!"

Sun Erga took out a box.

With a clatter, he poured the contents onto the center of the conference table.

Dozens of small black squares scattered, making a crisp clinking sound.

Everyone leaned in to look, and their expressions suddenly became strange.

"Z80?"

An engineer picked up a chip, his brow furrowed.

"Manager Lin, are we building game consoles?"

The Z80, an 8-bit microprocessor.

In this era, the most common places to find it were in simple calculators or electronic game consoles that children coveted.

"This is our main control chip," Lin Xi said calmly.

Boom—!

The conference room suddenly erupted.

"Manager Lin, don't joke around!"

The engineer stood up in a hurry.

"What we're building is a CNC machine tool!"

"This thing is 8-bit! The clock speed is only a few megahertz!"

"You want it to handle complex calculations?"

"This is like asking an ant to pull a train! It simply can't handle it!"
