Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Anyone know what they do to remove the enamel to get good contacts when they crimp the ends? I didn't see them do anything there.
I can only dream of laying a bead of RTV that well. Also narration from the How it's Made guy would be sweet.
This still looks like a beta process. Or a late alpha. Maybe someone with more motor manufacturing experience can chime in, but these are bog standard 4 pole motors, no? I'm also very surprised that Audi would let Tesla and BMW beat the pants off of them in the motor dept. The i-motors are a lot more sophisticated, (and yes, costly), but the efficiency and torque advantages are there.
But I could be wrong. Please internet, tell me why I'm wrong. (I seriously want to learn)
Man that is a lot of shrieking VFDs. And looking at the wi-fi antennas on the transporter sleds, I'm really curious about all the back-end that goes into controlling a system like this. I presume the individual stations are run by their own controllers, and some sort of overmind is regulating the whole plant.
The other thing that struck me odd is the tethered tools. I figure this is to keep them from getting misplaced, and also limits how much they can be put down on something that might enter part of the automation's track, but it also feels a lot like they're tied off to keep people from stealing them.
Then again, given how many tools walk off in our workshop, they're probably onto something there.
This reminded me of that outer limits episode where the AI starships kept and bred human technicians to do internal maintenance.
4 pole 3 phase, Wye wiring. Hobbyking'd (using lots of small wires in parallel) instead of hairpin windings like BMW. Hairpin style uses solid copper busbars bent into shape, which is more efficient for a lot of motors but also obviously way more expensive.
Unfortunately they skipped the rotor, which is the most interesting part. It's an internal magnet, like everybody else is using. Pretty tight competition right now on that front. 4 pole means there probably isn't much salience (the magnets are too big), which isn't surprising given the wire windings. More of an economy-focused motor.
Neat video but boy is it missing a lot of steps that I would have liked to see.
It just kept getting bigger and bigger throughout the process. Do they really mount two of these on each axle?
I understand that it is because it is business secrets that some of the most interesting steps are omitted. It annoys me non the less.
