@ManAnimal There is a sweet spot of efficiency in every electric motor, you are loosing energy before or past that point
read the greentext or whatever on the dude who jacked off at 90mph
yyup
Gears are also a power wasters though
well you are trading torqure for speed
best to run the motor at constant speed
tesla model 3 top speed is 263kmhr
batteries are mainly too heavy to run trucks as well
and change the ratio of rotation delivered to the axel
Fun fact: many huge robotic arms also have "gears"
Or rather two types of motors connected via common differential
One motor is an AC, another is DC
One starts moving an arm, another keeps it moving
yeah, that is one way to do it . another is usingg a capacitor
Called Motor-Generators
im not an electrical engineer but i study materials engineering
@Uksio keel.
almost certain teslas don't have gears that switch
These complicated setups are being replaced by a hybrid AC/DC motors that can do all that by themselves now
So differential coupling is a bit outdated now
did alot of retrofits of those type of units swapping the starter motor for a Variable Freq Drive
@Krisemann the only thing I remember is crystal structure and how the different ones form under different temps and pressures
@Jack of Trades yeah like iron FCC and BCC etc
and always 'better' in terms of efficency
but i'd take the drop in efficency to be able to 'drive' and EV
yeah it has a reduction gear
> one gear hahaha
> two gear hahaha
but it doesn't like go frmo gear 1 ro gear 2
differential
not a transmission
@Krisemann yeah plus some other stuff. I had the basic materials class, then a lot of stuff related to silicon in specific
Differential transmissions are also a thing
@Uksio so a mechanical part can do 1 million miles, but their argument is that they dont have a lot of mechanical parts so mmuh EV good
so not really a 'gear' in the sense we normally use it
@Jack of Trades yeah
electronics don't have that kind of reliability
you can only cycle a transistor so many times
well, they can
especaially an IGBT
@Vindi i. thinking of making some faces robotics for custom masks. Doesn't have to be great, but decent mimicking of face motion and mouth flapping would be a good start
@ManAnimal yeah but, it's a lot of times
