It's interesting to see the difference in processes between brands. Goes to show there's not some meta-company making all the production equipment, they're all bespoke. So much T-slot aluminium!
Thank you for putting this video together and putting it here on RU-vid. I understand, how electric motors work, their components and how they were made in the past. A little bit of narration would help non engineers better understand what they are seeing, but this an amazing video!
actually, human manufacture EM motors since 150 years ago. So it is not a new thing, actually it is a very mature technology for manfucturing considering Audi uses the almost same EM design as industry EM motor design.
Safety protocols don't allow it. They have to shut down large parts of the factory on a daily basis to do maintenance and such, but they move quickly to get it back up asap.
Copper is cheaper than using permanent magnets on the rotor. Also, AC induction squirrel cage motors, while awesome, are too heavy for small vehicle applications.
to save money. Winding rotors is much cheaper than using magnet and rotor winding design has worse performance of course, so nowadays almost all OEM uses magnet, even Tesla.
Well my japanese made compact electric car costumes the same as the VW ID3..so... Not too sure about that.. maybe 15y ago.. but they let themselves go a long ago..
@@somethingsuitable Там же батареи были от тягачей вроде, и не индус, а афганец. У списанных батареек электрокаров ёмкости ещё хватает для поддержания простейших бытовых сетей, их и "перезаливать" не надо, те же Audi показывали пример где аккум запитывает азиатские рынки с местными шалманами.
At what point does that incredibly slow robot payoff? How many motors need to be made? There's an incredible amount of specialty robots. I can see some saving in motor windings but the tasks that have been automated last how long before upgrades need done to the machinery or even maintenamce plus they have to be coded...I don't see how this ever becomes profitable.
Robots are generally programmed to the meet the cycle time requirements of the line. No need to wear out the gearboxes early. Also they are a little more precise when moving slowly.
@@franciscoshi1968 also high acceleration means higher power consumption. And that means you building power needs to be build bigger as you have to meet peek current requirements
@@random0252 with this nonstop rising prices of crude why do you think car makers develop electric cars now? Because electricity is cheaper and no engine oil needed
@@ex-soldier4341 where do you think the electricity comes from? Can't charge the car at night with solar, can't charge the car with wind when the wind isn't blowing, most of the world's electricity comes from fossil fuels.
@@gwot I'm not sure if you actually thought I didn't know electric motors existed, but just to be clear... it was a joke about how complicated the process was... meaning even with a million dollars, you'd have a hard time replicating it. Make more sense now?
@@henmich like i stated, I knew you said it as a joke, so yeah, I knew exactly what you were talking about. And I'd be more surprised if you didn't know motors existed, so that was a given as well.
compared to fully assembling an engine? I'd say it's about the same, maybe quicker. There are many more parts and bolts in an engine. The motor is also way less complex, it's essentially winding copper, putting it in a case and bolting it tight, the whole process can be automated, an engine is still partially man assembled.
Prepare to be bored then...because this is the future When we'll have optimized sustainable electricity production, ICEs will cease to exist Electric engines are boring because they are way simpler than ICEs, but this also mean that they are less prone to breaking, plus they are almost twice as efficient A world without ICEs will be sad, but at least we'll be able to comfort ourselves by watching old cars
