also literally everyone here has a tesla so theyre fucking gay

2019-07-15 16:39:39 UTC  

EV needs one gear to start from a dead stop and another to cruise

2019-07-15 16:39:58 UTC  

they're direct drive

2019-07-15 16:40:03 UTC  

but they aren't 'gears' per se

2019-07-15 16:40:04 UTC  

yup

2019-07-15 16:40:13 UTC  

they are just circuits

2019-07-15 16:40:14 UTC  

last thing EV needs is help from a dead stop, that's their most powerful state

2019-07-15 16:40:20 UTC  

And in high performance vehicles it makes sense to have a third gear because of diminishing returns at high revs of the electric motor

2019-07-15 16:40:27 UTC  

read on /o/ about it and one guy had an interesting theory

2019-07-15 16:40:39 UTC  

well actually I guess that graph contradicts that, but they're aren't piss weak like an ICE car

2019-07-15 16:40:42 UTC  

but they aren't 'gears' they just make them look t hat way

2019-07-15 16:40:44 UTC  

that they removed manual more and more because theyre easy to repair

2019-07-15 16:40:53 UTC  

Tesla has 2 gears

2019-07-15 16:41:05 UTC  

Like classical mechanical clutch things

2019-07-15 16:41:16 UTC  

@ManAnimal I'm from an entire planet of gears

2019-07-15 16:41:38 UTC  

motor speed control is just about how muchh current and how you choose to turn on the poles of the motor

2019-07-15 16:41:44 UTC  

You'd need some crazy complicated AC/DC motor to have a capacity to start from a dead stop easily

2019-07-15 16:41:47 UTC  

"The Tesla Model S, for example, is equipped with a single-speed 9.73:1 step-down transmission, not even a two-speed transmission"

2019-07-15 16:41:53 UTC  

You see, the thing about gear wars is that they weren't about the gears

2019-07-15 16:41:59 UTC  

How am I supposed to masturbate and drive in a manual? Asking for a friend.

2019-07-15 16:42:01 UTC  

it's called inrush current

2019-07-15 16:42:22 UTC  

any motor draws up to 10x the inrush current to break the inertia of a dead stop

2019-07-15 16:42:37 UTC  

once the motor is spinning, it only needs alittle current

2019-07-15 16:42:41 UTC  

@Grok you cant do that even when driving auto, lol

2019-07-15 16:42:45 UTC  

@ManAnimal There is a sweet spot of efficiency in every electric motor, you are loosing energy before or past that point

2019-07-15 16:42:55 UTC  

read the greentext or whatever on the dude who jacked off at 90mph

2019-07-15 16:42:55 UTC  

yyup

2019-07-15 16:43:04 UTC  

Gears are also a power wasters though

2019-07-15 16:43:19 UTC  

well you are trading torqure for speed

2019-07-15 16:43:30 UTC  

best to run the motor at constant speed

2019-07-15 16:43:43 UTC  

tesla model 3 top speed is 263kmhr

2019-07-15 16:43:53 UTC  

batteries are mainly too heavy to run trucks as well

2019-07-15 16:43:56 UTC  

and change the ratio of rotation delivered to the axel

2019-07-15 16:44:16 UTC  

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

2019-07-15 16:44:36 UTC  

yeah, that is one way to do it . another is usingg a capacitor

2019-07-15 16:44:47 UTC  

Called Motor-Generators

2019-07-15 16:44:47 UTC  

im not an electrical engineer but i study materials engineering

2019-07-15 16:44:50 UTC  

@Uksio keel.

2019-07-15 16:44:51 UTC  

almost certain teslas don't have gears that switch

2019-07-15 16:45:02 UTC  

These complicated setups are being replaced by a hybrid AC/DC motors that can do all that by themselves now
