Tesla has upped its standards once again with its revolutionary carbon-wrapped motor.
Coming with the Plaid version of the Tesla Model S, the carbon-wrapped motor is the most advanced
motor in the EV industry and intends to put electric cars on the same level with hyper-fast
cars from legacy automakers. But what exactly can this motor do and what does it mean for the
electric car industry? Is it something Tesla lovers can look forward to? Join us as we explore the
The Tesla Model S Plaid
When Tesla rolled out its Plaid version of the iconic Model S, it promised to introduce consumers
to a whole new experience. Its ability to produce 1020 horsepower and 1050 pound-feet of torque
sets it apart from other luxury sedans. Despite having a larger motor than any Model S variant,
the Plaid version weighs 4,828 pounds, making it over 100 pounds lighter than Tesla's Model S
performance. In September 2021, the production vehicle was put to the test on Germany's famous
13-mile Nürburgring racing track. The performance of the Plaid Model S succeeded in snatching the
Nürburgring record from Porsche with the previous time of 7 minutes, 42 seconds,
set by the Porsche Taycan Turbo S in 2019. The Plaid Edge is out with a little over 11 seconds.
As one of the fastest cars in the world, if not the fastest, the Plaid tops out at 200 mph
and can go from 0 to 60 mph in 1.99 seconds, making it the most powerful variation of Tesla's
Model S. Buyers who were able to test out their early releases were impressed by the car's speed,
which is largely due to its motor. Jason Kamisa, a renowned automotive writer,
was one of the first people to purchase the Plaid version when it rolled out,
and he commented on the vehicle, saying,
Judged as a Chiron-beating fast everyday luxury car, I must say with apologies to Rolls-Royce,
Bentley, Bugatti, Mercedes-Benz, and every automaker on the planet. Good luck catching
up. You'll need it. And at 130k, nobody stands a chance. He had high praise for the EV, calling it
The introduction of the Model S Plaid is a joy for people who want fast cars at an affordable price,
or serious environmentalists that need high-performance cars that do not have combustion
engines. It is practical as a sedan, as its interior and motor are more advanced compared
to the Tesla Model Y and Model 3. The Motor Behind the Speed
The carbon-wrapped motor is used in the Model S Plaid to take the EV's performance to ridiculous
heights. The car is equipped with three permanent magnet synchronous AC motors,
two at the rear end and another at the front axle. This is different from the typical dual
motor setup that other versions of Model S possess. The motor features a carbon-overwrapped
rotor that spins up to 20,000 RPM with a tight air gap. The carbon-sleeve rotor is one of the
shining points of the motor because it can achieve a higher RPM and produce a better
electromagnetic field than a rotor held together with a substance like metal. Creating carbon-sleeve
rotors is quite a difficult thing to do because carbon and copper have different thermal
characteristics, and to wrap a rotor with carbon fiber, the substance needs to be wound around the
rotor at very high tension. According to Elon Musk, making the rotor was challenging not only
because of the novelty of the task, but also due to the absence of adequate machinery. The first
thing Tesla needed to do was create the machine that would make the rotor because there wasn't one
on the market up till that point. The Model S Plaid motor's V-shaped permanent magnet setup
indicates that there is no iron connecting the magnets to the tip of the V-shape. There might
not be any iron bridge in the interpolar zone either, and this works fine for Tesla. In a normal
motor setup, having iron bridges at the tip of the V-shape in interpol area helps to provide
stability to the motor and provide a channel for leakage flux. In place of the iron bridges,
the Model S Plaid there is a fiber sleeve stabilizing the rotor, and the rotor can
achieve higher RPMs since there is no conduit for leakage flux. This also helps the motor to
withstand the frequent surges that will happen when speed lovers put the car to the test.
The fiber sleeves of the motor appear to be quite thick, thereby increasing the magnetic air gap of
the motor beyond the usual 1.5mm that a typical IPM rotor has. While the lamination in a regular
motor are in one piece, Tesla's carbon-wrapped motor makes use of them as a stack of pieces,
thereby increasing the power and performance of the car. The holes for the bearing, the part of
the machine that allows rotary motion, also has a remarkable mirror finish, probably done with the
roller burnishing process, something that is commonly used for brake components like the
cylinder. The same inverted package can be used for both the front and rear motors if need be,
and hitting the like and subscribe button is the best way to keep up with all the innovation Tesla
has in store for you. While the new carbon-wrapped motor is revolutionary in the electric car
industry, carbon fiber wrappings for equipment aren't entirely a new concept. It has been employed
in machinery like compressors and turbos. When carbon wrapping is used for high-speed machinery,
it can strengthen without added weight as it is 50% lighter than the typical alloys used for motors.
When used in other parts of the wheels, it results in a reduced gyroscopic force
and less steering effort while driving. The technology used in the new carbon fiber motor
gives the Model S Plaid 25% more peak power and torque without adding more mass to the car,
and it has received praise from engineers who got a chance to tear apart the car.
Most notable among them is Sandy Munro, who via his YouTube channel showed his appreciation for
the key features of the motor. Taking this direction with the motors makes the design
easy to build and maintain and leaves other vehicle manufacturers struggling to catch up with Tesla.
Issues with the Model S Plaid
Establishing the Plaid as a monster on the road doesn't come without issues.
Some of the deliveries so far come with obvious defects that have some buyers annoyed.
Buyers have noted issues like bad paint, rattling parts, and loose trims that most don't expect from
a Tesla product. On the flip side, Tesla is more than willing to deal with any issues brought
forward by a buyer in order to improve customer experience with the vehicle. Although speed lovers
would disagree, some would argue that 1220 horsepower is too much for a four-door road sedan.
Having that much speed in a street-legal car is a bit scary for some, and not needed even though
its ability to go 0-60mph in two seconds is the unique selling point of the vehicle.
Parker Neirstein, the owner of the YouTube channel Virgin Vehicles, also pointed out
some issues with the EV, even though he is generally thrilled with it. Despite Tesla's
claim of 348-390 miles range for the Plaid, in Neirstein's experience, the range was 150-170
miles. He does admit that he runs the car on Plaid mode, but the real-world range is still
a bit disappointing, considering what buyers expect from the car. The steering yoke of the
car is not an attractive feature of the car according to some buyers and have received
some scathing reviews, and there may be some truth to what is being said. The steering yoke
is good if you are driving high speed on the highway or trying to outrace a Bugatti or Porsche,
but when trying to do something simple like parking the car in tight spots,
it can be a bit difficult due to the unusual steering yoke. The Tesla Plaid owners also
spoke out about the placement of the horn button, which can be quite annoying to deal with when
trying to turn a corner. Some reviewers pointed out the braking issues their Plaid had, noting
the heat created by the brakes during testing. In some cases, the brakes got so hot that a warning
is displayed on the dashboard of the sedan, and the car tends to wander off the road, which is
unsettling. Testers like Cars and Drivers declared that the Plaid isn't just as good as the Porsche
Taycan, and reviewers like Edmunds straight-up called the car a waste of money. Much to the
of Tesla lovers. But no automobile is perfect, and despite the little issues with the car,
users are generally happy with its features and consider the EV worth every penny.
The car has many features that are worth noticing, and if there is anything we have
learned about Tesla over the years, it is that they will keep rolling out improvements on the
vehicle, and we can expect to see its motor take on a more complex design. The novelty of the
carbon fiber engine is setting up the stage for improving the torque and RPM of the current
Roadster's underproduction. The performance of the next-generation Roadster will be maximized
with SpaceX technology and a carbon fiber motor, and with a price tag of $200,000,
it is going to stand above Tesla's Model S Plaid in every possible way.
