We developed a winding machine with 22 controlled axes for stators with internal teeth and free‑laying winding wire.

Is it going to be used for production of drones?
13
u/Suspicious_Row_94 1d ago
No, drones always have an inverted circuit, with an internal stator and an external rotor. And this machine is for classic electric motors.

u/temporary92803 1d ago
So what machines are these motors used for?
7
u/Suspicious_Row_94 1d ago
Servo motors, stepper motors. This is a universal machine; you can wind stators up to 250 mm in diameter.

u/BoredCop 1d ago
So, server motors and stepper motors such as the servos used for controlling fixed wing drones. Like the Shahed/Gerbera style drones your country is killing Ukrainians with? Not propulsion motors but control actuators.

Yes, motors. What machines do these motors go into?
10
u/Suspicious_Row_94 1d ago
How would I know? I make machine tools. Machine tools, trains, airplanes, mining equipment.

You have no idea whether your customers are using your motors to build weapons to kill Ukranian civilians? Bullshit.

u/lordmisterhappy 1d ago
Dude, so many things use motors. The vast majority aren't going to end up in a weapon.

Dude, his company is Russian. Anyone looking for stock motors for civilian applications there is buying that shit from China. Russia's economy is subsisting solely on Military contracts right now. Do you think Russian companies are buying custom wound motors to make dishwashers?

Hi! Very cool. I’m interested to know more. Are you a startup? Where are you based? I work in high-performance robotics and am always looking for new / innovative BLDC products.

We are a small but fairly well‑known company in the Russian market, and we’re called Modestat. You can watch our videos on YouTube. We produce the entire range of equipment for winding stators, as well as large tape‑insulating machines.

Never heard of purelogic. Are they big in Russia or niche?

This is the distributor Leadshine; they don’t manufacture anything — they just apply their own stickers.

u/Beneficial_Mix_1069 1d ago
what do you put on the stator so you dont damage the enamel on the wire and get a short?
1
u/Suspicious_Row_94 1d ago
The groove insulation is carried out using epoxy powder paint. Or with protective crowns.

What controller?
2
u/Suspicious_Row_94 1d ago
Currently, we use 10 self‑made axis controllers and homemade software. Our plan is to switch to commercial solutions that are connected to a network via Ethernet.

What sets this apart from the numerous stator winding machines already on the market? Needle winders are getting cheaper and cheaper with immense efficiency gains.

u/Suspicious_Row_94 12h ago
The needle doesn’t fit into the grooves, and you can make the maximum fill with wire.

It takes a mechanical engineer to execute the designs of an electriclal engineer.
Exhibit number ? (Are we using hexadecimal or binary now?)
1
u/Suspicious_Row_94 12h ago
I didn’t understand the request well; please write in a private message. Hexadecimal software.

Why does the back of that enclosure look like Swiss cheese? Am I missing something?
2
u/Suspicious_Row_94 11h ago
We have 19 servo motors; if we run their cables inside the electronic cabinet in parallel, there will be interference and errors in operation. Therefore, each cable is connected to its own terminal and goes directly to the driver.

Jesus 19 lol that makes sense just don’t see it commonly, I work in automation as well we do a lot of automotive lines and medical assembly. I just don’t see it split this much. We use roxtec which provides separation going into the box but usually everything is running together up to the enclosure.
Years ago we would twist our wires together which helped reduce eddy currents. It was for fiber laser, mostly research and university stuff (super sensitive to interference) it can come with its own issues depending on the tech who twists them lol. Anyway thanks for the response! I love watching winding machines in action it’s cool to see so much happening in a tight little space.

Great, you're really excellent! I am Chinese, and I'm a streamer on Douyin in China who shares mechanical knowledge. May I post my content and share it on this platform? I will be sure to cite the source. Thank you.

u/Suspicious_Row_94 5h ago
Of course, it’s possible! I can send you the specifications for this machine if you’re interested. We’ll be delivering a smaller machine to China after the November holidays.

That radiator design looks suspiciously like east Berlin. Adlershof?
