EVs are always complex to understand. But u made it easy. Thanks ❤️

4 Motor Powertrain is Excellent in all conditions, and as per Driving Experience , Efficiency , power distribution . 👍👍👍👍

1. You can't break unity. When doing two or more motors, any motor doing regenerative braking would add more load to a motor pushing the car at the same time. With motors less than 100% efficient, this would drag down range and increase tire wear. Dual motor Teslas have reduced range for the same pack size due to increased mechanical drag from the extra components. 2. Teslas do torque vectoring on dual and tri motor cars by using the brakes independently on the wheels. Works pretty good. Of course a motor for each wheel is even more control and allows for things like tank turns. Mechanical brakes in EVs get relatively little wear, so using them to balance torque a little here and there is fine. 3. As mentioned elsewhere, you want the wheels to be as light as possible so they can be held to the ground when going over bumps and such. A heavy wheel because it has a big, heavy motor in it is going to fly up into the air when it hits a bump and not immediately come back down because of the mass in the wheel wanting to continue to go up after hitting the bump. This leads to terrible traction and loss of control of the vehicle. In addition a low RPM hub motor is going to be big and heavy because you need the motor area to generate max torque at wheel rotational speed. With a motor in the body of the car geared down, the max torque of the motor can be much less allowing the motor to be a lot smaller. For speed, the motor can just spin really fast when the car is going really fast when there is a gear reduction. You can only generate so much torque per unit of area of motor, but voltage to the windings can be varied for speed control. Because electric motors can spin a whole lot faster than an ICE engine before flying apart and the torque they can produce has a large factor in how physically large they are and because electronics can act as a variable transformer stepping the voltage down and such, only a single speed is needed. You just size the gearing so that the electric motor won't fly apart at top speed and size the motor to produce max desired torque considering the torque amplification factor of the gearing. Then the motor shrinks down as power is handled by speed of the motor and you can have a lot of speed before the motor flies apart. When you look at a Tesla or Prius, they take these lessons to heart and have very high power density electric motors that can spin at very high RPMs. When you look at the Chevy Volt for example, they did not understand this and so ended up with relatively large and bulky low power density motors that spun more slowly. 4. Leading on from #3, it would have been helpful to get more into the torque curves of these various electric motor types. When you get into the dual motor Tesla Model 3 and Model Y, they use two different motor types in part because they have different torque curves, so having one of each motor type allows them to distribute power during an acceleration to make better use of each torque curve. 5. As mentioned elsewhere, the motor descriptions you gave are not all completely accurate. I can't use this video as a reference due to the inaccuracies.

You have classified the Prius with the wrong type of motors! There are a lot inaccuracies in concepts. Newbies to EV technology beware with this video!

probably the best EV Motor Uses video review I have seen - keep up the good work and good luck with the channel !

This is a Good Tutorial on the different Electric Motors on EV we use! Thank You So Much for this useful tutorial! 🌷🌿

Good little review there, thanks. Two things I would like further explanation of 1) would not in-wheel motors not increase the turning moment of the vehicle by being further from the centre axis 2) and make the vehicle ride rougher due to the increased unsprung weight? Once more good job.

Thank you for such a video review, useful for all interested and beginners!

Lovely video. Your video clearly explained how electric motors in EVs work, even to someone like me without engineering background. Keep it up.

At about 12:25... "One of the motors can be used to power the car, while the other set of batteries can be recharging". Not unless you are plugged in while driving. 😁

Very clear explanation! I want 4motor because very strong and no overheat

Synrm also uses permanent magnets and Teslas are primarily RWDs.

There's also the twin motor front wheel drive configuration that many Chinese evs use. In most cases all wheel drive aren't available, as the frames were designed only with fwd in mind, and available space and weight was already used for battery. There's no transmission, no rear motors, only small passive generators integrated into rear break rotors for clawing back breaking power. The idea was to keep everything as simple, cheap, efficient, and reliable as possible. We may see this configuration more often as evs come down from the luxury market and become mainstream.

EV is a new concept we are to understand. You tried to make it easy. thanks.

Great explanation, very easy to understand especially for beginners.

Finally I conclude that its the end of differentials and other mechanical parts wich normally are equipped on the ICE cars. But I think that this permanent magnet engines are the best effective and efficient engines ever. But the problem still on the batteries the weight affects their own performance overall And this is a topic on that powertrain automakers need to solve!!! Finally, the future tells about the scopes about the evolution of the batteries.

Some corrections needed here. The SynRM you're talking about at 6:40 is what I've got in the back of my Tesla Model 3 RWD but it also has permanent magnets embedded in the rotor. As far as I'm concerned, you cannot improve on that provided the permanent magnets don't demagnetize over time or due to heat.

Superb! Thanking for sharing this video! greetings from Papua New Guinea!

This made my day

I came from Previous video about gears by searching for types of motors and find this video. Thanks for informative videos

I believe in the in-wheel motors for my EV concept.

Superbly explained 2 words for the video "Simply Awesome" Good bless you keep the good work going

Practical and natural progression suggest all EVs will be four motor drives. You get best of the both worlds. Efficiency (good for climate) and extremely responsive car (like a Ferrari!)

Relating to motor configuration I see two favorable set-ups. The single motor drive is the best for electric conversion of ICE cars. The best natural electric car configuration is the four hub motor concept based on AFS motors as the best fitting package to the wheels.

بہت محنت کی ہے اپ نے.

A motor for each wheel is the best!

I wished if there was 1 million like button for the excellent review ❤❤❤❤

I prefered the 4 all wheel motor. Its is perfect for vectoring and more power delivered for each wheel.

Thanks @ lot for information... According to me 4 motor will b good

I find that the dual motor system is the best for EVs power density and power control.

Wow, it was really nice to have this video here. By the way, I will research Charging stations' impact on smart grid power quality and stability, which is vital for power industries and governments to consider the increasing usage of EVs in grid power. It seems that up to many decades, the EVs will be fully having roads under there own wheels. Which makes this research really efficient. If you have any kind of research cooperation program, please let me know.

Nice content 👍👍❤️ Thanks for the information ❤️

I would prefer a 1 liter, 70HP triple cylinder engine, paired with a 40HP axial Flux motor/generator, to cruise the car at a fixed speed, and a 100hp rear motor, for acceleration.

Bro literally give this huge information in a nice way and shorter way 2 year ago

Electrolmotive diesel trains use double squirrel cage induction motors because they are very reliable motors. Its has high starting horsepower and torque set up but they’re large in size.

Very comprehensive video on EVs motor systems. I feel like going EV, like right now.

greattttt video, can you make a detailed vid on welding type since my 1st year of engineering is online :)

Using a poorly written script that is read by a computer text to speech app is resulting in some confusing wordage in places. But it is overall a useful video.

Good video, but wish in-hub (within wheel) motors had been more extensively discussed.

Sadly we are going to see a lot of single motor vehicles before manufacturers start bringing down the cost of true four motor AWD unless its done under a government regulatory mandate.

Excellent explanation. 4 Motor power

Make more videos @engineerspost.its very useful.. keep going so one day you will get one MILLION SUBSCRIBERS

Very good, Very informative. Congrats, wish to hear from you soon

Clarification of ev based on motors really appreciable.Thanks for your information.

I am a retired engineer, I worked in Medical Systems, Factory Automation and Robotics for 45 years. Now I own a 2104 Corvette and the 2024 E Ray looks very promising. BUT they did nothing for efficiency, MPG or emissions. Only Power and Speed. I hear you say "When In Wheel Motors arrive" . OK I want an In Wheel Motor for the front two wheels of my 2014 Corvette. I think Chevy Missed the opportunity for cake and eat it too in the E Ray. I think we need to focus on Retrofitting existing vehicles into AWD Hybrids with In Wheel Motors and Single Pedal controllers, Regen and Vector guidance. My goal is longer range, AWD, bid power when needed and power assisted Gas drives for Max MPG and Lowest Emissions such a E85 Conversion to Gas motor for emissions and power. Where can i go to get a Conversion engineered and practical in my remaining lifetime, I am 74. My 1st Vette was a 1964 now this 2014 may be my last one. I like the car and just need to make the best for the future in emissions and power. Front Engine rear Drive feels so good to me after owning 8 Corvettes 3 of them supercharged its a format I like. I have tried the known motor sources but they are all lined up to supply the Major Manufacturers NOT the After Market vehicles. Trucks and Cars need love too. I thought making the Corvette conversion first could open the AWD Hybrid conversion market up to all the other Gas Drive vehicles. Delivery, Pick Up and sedans why not? Any feedback or comment welcome. I learned good thinks in this video and will look for others on your channel. Dennis

Great explanation

meri Fast year ki pahli semister offline Hui thi aur ab third year ki last semister offline ho Rahi hai mechanical engineering ki

In the future they should make electric motors conversion for muscle cars to drive the transmission

Rivian looks soo good

Thanks for sharing this good info...

I will go for the 4 motor configuration since it has the most power combined with 4 motors. I like the idea you can run two motors while the other two are not running and the batteries will recharge while the car is running.

10:40 more efficient at a higher altitude ........... ?? Great breakdown of electric motors .

Thank you…

For any case: the toyota prius is not simply an electric٫ Comes with a I3 - I4 hybrid engine 📌

The future is gonna be great if the World doesn’t come to an end first! Constant improvements and innnovations!

Best video among all but explain further about it's electric components ✌🏻

BLDC and PMS is more or less the same for me. Also the axial flux machine is just another geometry of this principle, which allows for iron free systems.

MOTOR ; ALTERNADOR : GERADOR ; MOTOR - ELÉTRICOS ; WORLD ; MOTOR : ELÉTRICOS : DIVERSOS : UTILIDADES : INFINITOS : APLICAÇÃO : UTILIZAÇÃO !!! ; MUITOS PRODUTOS : SERVIÇOS !!! ; MOTORES : ELÉTRICOS !!! : FUTURO : GRANDE !!! .

Given all that's being said about electric Motor evolution , control systems, gyroscopes , robotics etc , looks like a single motor , single seater , single wheel system set up on a single pole provisioned with stabilized seat and self navigation controls for the commuter will be the next important development in the coming years.

Thank you so much for teaching

You aired to mention the inverter for AC motor to convert the battery DC. Only series wound motor does not require an inverter. Thyristor is required for speed and current control.

single TYPE motor, is my preference. For simplicity reason. 2 motor, front & back, is simple enough. Quad motor, 2 front & 2 back, only if it can turn to 3 / 2 / single motor, when 1 / 2 / 3 motor develops a problem.

This video explains how efficient electric motors are compared to an internal combustion motor. They have less moving parts and are smaller in size.

Thanks again for this wonderful video

I wonder how in-wheel motors can be considered the best when it adds considerable un-sprung weight which will adversely affect handling.

Well, single motor driving a diff is real popular. The heavy truck community seem to love that format as they are calling them e axles. I was hoping to rid myself of the diiff as it requires regular servicing which is the primary attraction of BEVs to me. No oil changes-no emissions testing-no transmission servicing-no driveline nor U joints to service-no cooling system...Win-Win-Win. If Tesla can make that $25K eco sedan happen they will have a monster on their hands & the conversion to EVs will accelerate to an unbelievable pace. !

Thank you for sharing

Another well-animated educational video, rife with factual errors, narrated by text-to-speech

Best video on the subject and very thorough, very informative. Description, comparision, and Pros and Cons are well explained. I liked your video. Thank you for sharing.

Excellent Information Presentation.

Dear brother you have done a great job by uploading such a highly useful and informative vedio. Best wishes Naeem ahmed bhatti From,, Islamabad, pakistan

The best improvement would be to eliminate the charge cycle entirely. Flying saucers ( some ) use Kohler converters. But what is the strength of the EMF field at ground level? There has to be magic in the mix.

My preferred configuration for a practical EV is to have two motors in front and parallel to the rear axle with a two speed gear box which would allow just one motor to be used around town in a low gear where maximum rpm might get up to any 60 - 70 km/h and and then high ratio could be used with two motors with maximum rpm allowing a top speed of something like 115km/h as 110km/h is the maximum speed limit where I live. The top speed limitation caused by the gear ratio allows the lowest possible torque motor to be used as torque is proportional to current draw, also the lower the torque the lighter the motor. I also have had a less practical design concept that I thought up in the early nineties before lithium iron batteries became an option. The idea was to have something like 10 small wheels about the size of the original mini minor wheels all with built in hub motors which would be all steerable except for the pair second from the rear. Suspension and steering may be similar to that of the front wheel of an aircraft to allow room for the less energy dense batteries such as nickel metal hydride batteries and/or a flat horizontally opposed engine and alternator so that it all could be hung under a higher than normal floor pan. This meant that it could easily be changed from hybrid to only batteries when battery technology improves. I’m not an engineer but was thinking that this design might reduce the need for localised high strength at the suspension points since there would be ten of them instead of four and I was hoping that this would make it much easier to design the body from aluminum which requires less energy to recycle and even better may not need to be painted but polished like aircraft. Also since it would be suspended at ten points the suspension could be fully extended without the suspension being too hard and the advantage of this is that it will not drop wheels into pot holes which makes it more tolerable on bad roads with the advantage of less unsprung weight that you get from small wheels. While it may be a bit expensive to manufacture there are two trade offs, 1) as already mentioned the possibility that it may not need to be painted and 2) solid state components that only need to carry one tenth of the current for each wheel would be far less than one tenth of the cost at least it was the case back in the nineties. It could look a bit like the chariot from the 1960s sci-fi show lost in space without the tracks. I think that the uniqueness and practical advantages would have attracted a lot of buyers.

Superbu explanation

alternator, compesor ,fan dual function, + smallest dynamo x + metal parts cast expert

One battery charging while the other is driving!! Sounds like you have invented a perpetual motion machine.

In a turn in any vehicle trailer or kids wagon the outside wheels travel further because they are going around a bigger circle, so they are rolling faster.

They missed the Permanent Magnet Synchronous Reluctance Motor (PM SynRM) used in the Tesla Model 3 as well as Raxial Flux Motor used by Koenigsegg.

What is the best car engine to make at home? What do you recommend for an engine?

Excellent video!

Nice video 👍 nice description

Thanks, Great Video.

The video was very informative. I wanted to know more on the Axial Flux Motors and their application in production(Specially One from the Koeinseg Regera)..

High quality Motor❤🪬💚🌏

second and third motors - actually same motors With this separation you should tell about all 3 tipes of brushed DC motors

In wheel is great

Excellent 👍👍👍

Good video useful for all about new technologies, for sugarcane juice making machine which motars is good 🙏

Thank you

Thanks alot good information

well, tbh i would be happy with all of them, maybe except for the brush motor. pretty much all options are better than ice engines regardless. its the how can you charge your vehicle, which creates the problems. especially in europe, where private housing is reserved mostly for the upper class.

Nice.

When cornering, how to independently measure which wheel the vehicle needs more torque, is a gravity sensor used here?

I have an 1994 Toyota pickup truck with a 2.4L 22RE 4-cylinder and while it has been extremely reliable, it is pretty underpowered. I had often wondered if it would have been possible to make it a gas/hybrid by having an electric motor going inline with the driveshaft. I would like to think of it as more of a helper motor that would help with faster acceleration and maybe a bit more power when I need it. All the while not drastically changing the engine or transmission. I saw a video of someone attaching an electric motor on a V8 engine setup similar to a belt driven supercharger. The power train remains the same but they added this motor which gave a bump in power while also increasing mpgs. That’s what I would want. It puzzles me why it never came to market because I feel like that would be perfect for many car enthusiasts who love old cars and old engines but also want to embrace in some new technology or to get more power.

perfect

Could you expand this discussion to include hub motors? I’ve been watching the development of the Aptera and Lordstown Endurance EVs both of which use hub motors. There seems to be a lot of advantages with these motors but what are the disadvantages?

Nice video!

thanks

Neither Tesla nor Polestar 2 offer FWD options as mentioned at around 9:08 . Only AWD and RWD are available.

I would love to see the cost of these engines, me and my brother has been thinkin about building our own ev.
