Tesla declared at its investor Day event for 2024 that it would offer an electric motor without the
use of rare Earth elements there are reasons why it matters even if this might not seem
like a major concern to most people following Tesla's announcement companies that produce
Rare Earth elements may experience pressure but for the vast majority of people this is
the next step toward a less expensive EV and so let's investigate further how is Tesla going to
make this happen hello everyone welcome back to Elon Musk Evolution where we bring you the most
recent news about Elon Musk and his multi-billion dollar companies space news and the latest science
and technology but before we begin make sure you subscribe to our Channel and click the Bell icon
so you don't miss any of our amazing videos Rare Earth elements are probably something that the
majority of EV buyers never even consider much less are aware of or understand their
significance on the other hand as EVS become more popular those who are opposed to them will go to
tremendous links to point out their flaws there have been a variety of myths and horror stories
over the years many of which were founded on untrue assertions but were spread by those with
a bias against the new technology it would be preferable to avoid using Rare Earth elements
in this scenario they are frequently pricey hard to get and sourced and produced in Nations
like China Rare Earth elements are undoubtedly a matter for concern as the U.S attempts to reduce
its Reliance on other nations for the sourcing and processing of materials there is already a
lot of false information out there regarding the use of rare earth materials in EVS the lithium-ion
battery its potential for fire the materials it is built of how and where they are mined and an
endless list of other factors are the primary issues of contention against electric vehicles
reports claim that although modern EV batteries include essential minerals Rare Earth elements
are often absent from them as the West strives to compete with China's Supremacy in the production
of rare Earth elements including neodymium prasidinium erbium and dysprosium the two largest
manufacturers in North America are MP materials based in California and Energy Fuels based in
Colorado the magnets in electric vehicle Motors employ ndpr Tesla however asserted on Wednesday
that a subsequent generation of vehicles won't require the components but it made no mention
of the specifics of the anticipated technology including when it would be available and the
scope of its application current producers would still have a market according to analysts at Bank
of America Global Research any transition to new technology will likely take a significant amount
of time and it is unclear if this will be adopted in all Tesla models or by other EV producers Bank
of America said in the study published Thursday while we do acknowledge the downside risks posed
by current or future technological developments the strong long-term growth outlook for permanent
magnet use in EVS wind turbines expected to grow two to three times by 2035 suggests there may be
enough room for multiple Technologies to co-exist in recent years Western governments have invested
billions of dollars in critical mining policies funding businesses and initiatives at the Vanguard
of the transition to Green Technology sparked by worries about global warming they aim to protect
the sources of the rare Earths Cobalt nickel and Hopper that are utilized in the majority
of contemporary Technologies including defense and cell phones approximately 80 percent of the
rare Earth's Market according to analysts is controlled by China last month MP materials
decided to supply ndpr from its Mountain Pass mine in California refined by businesses in
Vietnam and the Philippines rather than China as it had previously done to tokyo-based magnet
manufacturer Sumitomo Energy Fuels which has development projects and Manufacturing facilities
all across the U.S Southwest last month ventured into Brazil by spending 22 million dollars to
acquire a rare Earths project in the state of Bahia neocore development said last month that
its demonstration plant in trois Riviera Quebec generated a high Purity mixed concentration of
rare Earth elements in Southeast Nebraska it is getting ready to spend 1.2 billion dollars
developing its Elk Creek critical minerals project australia-based vital Metals seeks to accomplish
an initial Economic Review by June of its nicolaco Venture 110 kilometers southeast of Yellowknife
Northwest Territories it's improving a 55 million dollar processing plant in Saskatoon Saskatchewan
though its off take associate in Norway isn't anticipated to be geared up until next year
The Wider stock markets rose on Friday as a result of information suggesting that the U.S
Services sector expanded last month in hopes of a recovery in China shares in rare Earth's producers
and developers were mainly up throughout this period after falling on the news from Tesla's
investor day some producers rose again Bank of America argued that the sell-off was excessive
and pointed out that manufacturers had been working for years to develop Motors without
rare Earths Toyota announced in 2018 that it would keep working on ndpr for at least 10 years
despite developing a new magnet that could not completely replace ndpr this shows how long it
takes to switch to a new technology according to Bank of America there may be other efforts being
made in the field of Material Sciences that could ultimately endanger the use of ndpr-based magnets
in either case these advancements typically have lengthy lead times for development the researchers
also identified a possibly far-fetched solution in studies on space rocks being conducted by cam
Bridge University in the UK and Northeastern University in Boston tetrotainite and iron
nickel alloy found in meteorites will be created synthetically in order to replace rare Earths
tetrotainite is a cosmic magnet that naturally develops over millions of years but researchers
have proposed a way to create it artificially according to a statement from Bank of America
however the researchers also noted that additional research is necessary to establish whether it will
be appropriate for high performance magnets and whether it can be produced at scale in the
commercial sector and now let's get to the bottom of this let's check how a Tesla car works since
1835 there have been electric vehicles on the road this is an important period of time but you cannot
compare them to the pace of modern electric bikes let alone that of regular cars however in the last
two decades electric automobiles with futuristic Sleek forms with killer horsepower and torque have
become more common the automotive industry is experiencing rapid growth due to electric
vehicles by 2025 it is anticipated that these high performance noiseless and pollution-free vehicles
would surpass those with internal combustion engines since its founding in 2003 Tesla has led
the industry in producing cutting-edge electric vehicles but how do electric vehicles work is
there an engine inside a Tesla what is the process of a Tesla engine in this video we'll discuss
them in more detail however let's first check to verify if Tesla automobiles actually have engines
does Tesla have an engine it is astounding how Tesla constructs their vehicles you'll
wonder where's the engine as soon as you lift the hood where is the engine of the Tesla Model 3 you
might wonder if you own one or do they possess an engine no to put it simply the internal combustion
engines used by Tesla are electric they are powered by rechargeable battery-powered electric
motors instead the electric motor is mounted on the back axle of Tesla vehicles with rear-wheel
drive the front and rear axles of all-wheel drive Tesla cars are equipped with electric motors too
these electric motors work using rechargeable batteries so as opposed to purchasing gasoline
or diesel at a gas station you occasionally need to recharge the battery your electric vehicle can
be charged much more quickly by installing a wall charger or by plugging in into a regular outlet
Tesla manufacturers constructed their vehicles similarly to other automobiles on the road they
do however employ a distinct configuration how do Tesla engines work what kind of engine does an
electric car have since they don't have internal combustion ones you should be aware that strictly
speaking electric motors are what are used as the engine's in electric cars you will discover how
Tesla electric cars produce more power in this phase by studying the science of the induction
motor inverter lithium-ion battery power source and most importantly the synchronized vehicle
mechanism in a usual step-by-step fashion around a century ago the famous scientist Nikola Tesla
created the induction motor the engine of Tesla automobiles induction motor the rotor and the
stator are the two parts that make up an induction motor there are conducting bars in the Rotor at
each Edge the bars are normally short-circuited the coil of the stator receives three-phase AC
power a revolving magnetic field results from this Tesla's induction motor produces a 4-pole magnetic
field the electric flow on the rotor bars is then induced by this RMF causing it to turn
in an inductor motor the rotor lags behind the rotating magnetic field as a result the induction
motor is without brushes or a permanent magnetic field despite this it is strong and powerful and
induction motor's main benefit is that its speed matches the alternating current power
source the speed of the vehicle can therefore be changed simply by changing the frequency of
the alternating current Supply Tesla and other electric vehicles are now faster more dependable
and simpler to drive thanks to this technology the induction motor speed has a range from 0 to 18
000 RPM this is one of The Cutting Edge advantages of electric vehicles over traditional gasoline
and diesel engines ice-powered Vehicles do without a doubt create usable horsepower
and torque but only within a specific speed range however the induction motor where does
the induction motor get its power the battery pack all of the induction Motors usable power
is generated by the battery pack the battery produces direct current but it is necessary to
convert it to alternating current the inverter is used in this situation small lithium ion cells
similar to those found in laptops and cell phones are used in the production of Tesla's battery pack
create the necessary power to run every system function they connect these tiny Lithium-ion
batteries in parallel and series in order to keep these tiny battery cells from overheating Tesla
also installs a glycol coolant that flows via the inner metallic tubes between the gaps instead of
using a few large cells many small cells ensure effective Cooling and this contributes to a longer
battery life the tiny cells are put in modules by the makers the majority of Tesla vehicles
have 16 modules each made up of seven thousand tiny lithium-ion battery cells the inverter
the inverter regulates the frequency of the alternating current which regulates the induction
motor speed the amplitude of the alternating current can also be delayed by the inverter
this implies that the motor output can be managed by the inverter inverters serve as the brains of
Tesla and other electric vehicles in this way the glycol coolant returns to the radiator in front
of the car to cool it down after absorbing Heat the drivetrain let's look at Tesla's
Drive trains and how they interact with the Tesla engine which is actually a Tesla electric motor a
transmission transfers the power produced by the Tesla Motor to the wheels the Tesla transmission
uses a single speed transmission algorithm it is imperative to note this is very dissimilar to a
traditional transmission how many gears does an electric car have electric automobiles will seem
unusual to you if you first learn to drive in a car with a manual transmission the majority of it
not only has single speed gear but also lacks in a gear shifter when you first get into an electric
car you'll notice there isn't a gear stick or gear lever to allow you to change between gears ranges
when you stomp on it there won't be any noticeable gear shifting because the builders constructed
it with an accelerator rather than a gas pedal having said that do electric cars actually have
gearboxes how many gears are there in an electric car it all depends on who you ask about what they
have to say to these questions if you explore Authority Automotive websites you'll get diverse
responses like no transmission two-speed gearbox and electric vehicles to one gear in this episode
we'll get straight to the point and straighten out what drives electric automobiles the electric
vehicle transmission system let's define a transmission before moving on a mechanical device
called a transmission can base power or multiple torques therefore every car has a transmission in
this engineering mechanical sense instantaneous quiet and smooth acceleration is one of an ev's
most distinctive qualities this is so because the way electric vehicles propulsion functions differs
from how ice Vehicles do their fuel source is the main distinction between EVs and Ice cars when you
push the accelerator pedal on an EV the electric motor spins quickly since the battery's electric
current was transferred to it a single alternating current motor is typically fixed to a gearbox in
electric vehicles electric vehicle Transmissions are more appropriately referred to as single speed
gear reduction units because all the gears are connected and rotate at the same time in contrast
to ice Transmissions that have several gear sets that spin at various intervals the motor's RPM is
decreased by the single speed gear reduction unit to a more manageable rate which will drive the
wheels at a ratio of around 10 to 1. that being said depending on the pace you're moving at there
is no clutch no clutch engaging and disengaging and no shifting of different gear ranges
ev's AC motors have a maximum speed of 18 000 or more RPM this enables EVS to produce enough torque
at high speed with a craving sweet spot of 30 to 40 mph range they equip the beast's 2021 Tesla S
plaid model with an AC motor that turns as fast as 23 308 RPM Little Wonder it speeds up to 200 miles
per hour smooth acceleration is achieved because rotational forces are transmitted instantly and
directly from the gearbox to the wheels and since there is no need to change gears to move from one
range to another the friction wear and tear of engaging and disengaging clutches is stopped in
the absence of several gear sets overall EVS efficiently use 77 percent of the electric
current stored in the battery to power the vehicle whereas gasoline-powered cars use 12 to 30 percent
of the energy stored in the gas tank to propel the vehicle forward in addition it uses a lot of the
gasoline for heating manufacturers set a limit for the efficiency of the motor that transmit power to
the wheels of electric cars at 89 to 96 percent compared to ice Vehicles transmission efficiency
of just 14 to 26 percent four different types of transmission systems are categorized by experts
for use in electric vehicles at Transmissions AMT CVT and DCT DHT Transmissions how many gears
do electric cars have electric vehicles lack both clutches and gears contrary to typical gasoline or
diesel-powered automobiles electric vehicles lack multi-speed gearboxes as a result of producing
more RPM than typical ice Vehicles they have a single speed gear instead also known as a gear
reduction unit in contrast to ice Vehicles which can reach speeds of four to six thousand RPM per
minute EVS can travel up to 18 000 miles within a small range of gear ratios or engine speeds
internal combustion engines provide Power and torque that are employed to accelerate the vehicle
the engine must sustain the appropriate torque and power for the ice vehicles to accelerate with the
help of the transmission gears the driver is able to maintain the necessary level of energy so that
he or she can efficiently accelerate or decelerate without sacrificing the necessary torque prior to
the RPM increasing significantly and necessitating a shift to second gear the first gear can only
maintain a driver's modest speed EVS on the other hand produce all of their torque at low
speeds even under a thousand RPM it is preferable to keep your RPM low at or below 2000 since as you
increase your RPM your torque diminishes electric vehicles can still have numerous
gears despite this to boost the car's power or Torque though they are not required how many
gears are there in a Tesla car compared to ice automobiles which have more than 200 moving Parts
Tesla cars have just 17. in contrast a typical gasoline-powered automobiles which have various
gears and different speed ranges that are mounted on the back of the crankshaft Tesla vehicles have
a single speed transmission without revolving gears Tesla vehicles don't require numerous
gears to enhance torque and power which is one reason why they have single speed transmissions
two Teslas have gearboxes a single speed gear reduction mechanism with a fixed ratio of nine
to one is standard equipment on all Tesla vehicles no transmission is required because the motor can
rotate backward and at low speed achieving up to 20 000 RPM and a maximum torque at 0 RPM
do electric trucks have a transmission you might be wondering according to our
definition of transmission every vehicle has one thus referring to the gear reduction unit as a
single speed transmission is acceptable why do electric cars only have one gear
s are not necessary in electric cars because they don't need a clutch most manufacturers
do not include multi-speed transmissions in most electric vehicles unlike those that are powered
by conventional gasoline and diesel engines instead they have a single speed transmission
with only one gear why is that exactly this is due to the fact that they can generate both high
RPM and low torque are there transmission fluids for electric cars the only three fluids that EV
manufacturers include in electric vehicles are coolant windshield washers and Brake
fluids only the majority of EVS use these some use something else meanwhile that ends today's episode
