Let’s look at a simplified explanation of a three phase, permanent magnet AC motor. It’s really comprised of two main parts, the stator, which has copper coils and is stationary, and the rotor, which has magnets on it and rotates.
In order to force the rotor to rotate, the stator has three sets of magnets, though in reality it could be many more. The magnetic force for each magnet is created by a wound copper coil. If you pass current through a copper coil, it creates a magnetic field, with a north and south pole, based on which direction the current is passing through the copper wires. These six magnets make up our stator, which remains stationary. In the center, we have our rotor, in this case a simplified rotor which is simply a magnet that rotates about its center, with a north and south pole.
As you pass a current through the copper wires, supplied from the electric car’s battery, that current creates a magnetic field in a pair of electromagnets. The north pole of the magnet in the center is attracted to the south pole of the electromagnet, and the south pole of the magnet is attracted to the north pole of the other electromagnet. Similarly, the north and south poles of a separate winding will repel the magnetic rotor, and in combination the magnetic forces will cause the rotor to spin.
Another important thing to note is that if you reverse the current in one of the sets of electro magnets, you will reverse the poles for that magnet. As the the rotor spins, a controller will manipulate the current in the electromagnets, making sure the rotor never fully lines up with a magnetic pole and is forced to rotate. As you can see, the stator creates a rotating magnetic field, and the rotor spins with it. The stator rotates the magnetic field faster and faster, forcing the magnet to rotate faster and faster as well, accelerating the vehicle.
Since power is a function of both torque and RPM, how much power this motor produces is dependent on a couple factors. First, how much current and voltage is supplied, which will increase the strength of the electromagnets, which will in turn increase the torque on the rotor. And also how quickly the current can rotate around the stator, which will ultimately play a part in the peak RPM of the motor.

Car guys of the future: I used liquid nitrogen to get my Tesla to 5GHz.

Luca Della Bonzana my Tesla has triple 4k monitors and 4 GTX1080s in SLI
Mine has RGB, that's like... 42 more hp I'm told
First electric car manufacturer with open-source engine mapping will win the future of car culture.
Torkild Kahrs You are absolutely correct. I will wait till there is an open-source friendly electric car. Ideally it would be the last one you would need to buy.
Torkild Kahrs You just hit the nail. Electric cars are appliances rather than the dream cars.
See those custom built PCs? Just like them.
Tesla opened up years ago
And a nice little side line in supplying new motors, inverters and batteries to all the people who'd blown them up by changing critical values without knowing what they are doing.... ;-)
Even if it was open-source, there is not much you can do unless the stator is going to handle the increase in voltage applied to it..as well as everything else in line with the motor. I am sure it wouldn't be too hard to get larger cables to the motor, for instance, but I think the real modification would be a complete motor swap with an open source inverter allowing for changes to the vehicle as well as the ability to output voltages and amperage above stock levels. It would be super complicated to program considering that the motors in an electric vehicle are also tied into the ABS/traction/regen braking/stability management system onboard, within the inverter programming. At least this is in the case of all electric forklifts/machinery that utilize most of the same technologies today, but obviously not as powerful in most cases. If you increase voltage to a 3-phase stator past its operating voltage peak, the coils become saturated and end up just draining your source of power faster. No increase in actual power happens after a certain point, only saturation and smelly wires.

So basically electric cars are like electric rc cars. If you want to go faster get a better, bigger motor or change the gearing, and also get a better big battery with more discharge.
This simplicity is what makes electric cars great.
Except simplicity is not the problem here.
I learned about the basic dynamics for myself...I took a junk toy RC car that barely did 5mph, upgraded everything with (cheap) hobby grade hardware like a Lipo and brushless motor and it goes 30+ MPH now. I even had to get an ESC tuner to make it driveable, the default setting on the drag brake made it flip over violently, so I had to turn it off. It felt like I was building and tuning on a real car.
@@ElektronikArzt "change the whole motor and battery to gain power" "simplicity"
@@whcwcjecjecuecuw6654 thats because changing a EV engine is far easier and less complex than changing a IC engine.
In fact, a EV engine is far less complex than a IC engine will ever be.

Great video, as always! This video was jam packed with useful information, and this video ultimately gave me a clearer insight on Electric Vehicles.
I hope to be an Automotive Engineer/Designer in the future... So, thank you for all of the time and effort you put into your videos. Keep it up! 👍🏽
this guy is perfect for keeping up to date on new tech, learning how new tech works, and also learning fundamentals of the past... all in an informative and extremely understandable way... this channel is bloody perfect lol
Hudson Stronck, I have to agree with you! 👌🏽
This isn't " new tech " as you call it.....and the explaination was very ......very basic !
+pol1250 Yes it is basic, and that is why it is easy to understand for the broad audience. What point were you trying to make though?
Dunno, Im an electrical engineer, and theres not a huge amount more to an electric motor. Theres kv, the timing of the motor(which is somewhat equivalent to ignition timing), the winding type which has a bearing on torque output at low RPM's and not much else. Thats the beauty of electric, theres so little to them mechanically compared to petrol- with intake, exhaust, NA vs forced induction, injection+ignition timing etc. getting the most out of the motor itself is relatively straightforward. Getting the most out of the system: the batteries, the motor driver and so on is where you make the gains in weight and efficency+heat output, and that would be a much more in depth discussion.

I'm writing a research paper on the future of electric cars and how they will effect the combustion engine. Really sucks that TH-cam and blog posts are not considered as "credible" sources for research. Would make the project so much easier
Andrew
I've learned more from TH-cam than I have from all the classes I've taken... it's kinda sad. Check out ave if you're into engineering outside of cars... and good ol entertainment.
check out @fullychargedshow, they are the best source of EV and renewable engery news. You will find everyting you need there. Chears
Seems like a good excuse to speak with industry experts as he does in these videos.
Could always contact EE himself, and ask him for contacts :)
Or just use the sources in the descriptions of the videos if they managed to add them. You will eventually find the papers, reports etc if you constantly search the sources of each article, video, etc.
electric cars are fun as hell! the only downside is the lack off WHROOOOOOOOOM
Nice motor graphics. That alone already gets a big thumbs up.
As you have explained, you can power up an electric motor depending on how strong the power current or on how strong the magnets the electric motor has. In this case, we can modify (or create) an electric motor with stronger magnets to provide more torque with a lower power source.
I think that's gonna work on electric cars for more power efficiency (just like modern engines for normal cars for fuel efficiency).
I've learned a lot from your videos.
You really simplified this for me thank you!!
you mean i CAN'T turbo a tesla???? what?????
a turbo needs fuel so no
KyoKyoM99 of course you can't, you need to supercharge it
Tesla's dont have exhausts though xD
Split Shockwave I see what you did there
kaposvári bando dude idk what you're talking about. my civic's turbo is fuel injected and it runs like a charm. (sounds like a supercar too ngl)
Easy, duck tape a 9 volt and you got an extra 20000 hp
Finally the magnetic field and current changes N&S poles thus rotor spins explained. So many videos never get this point explained so simple as yours. Thanks
Nice video, as always. Some solar cars at WSC and FSGP/NASC used the opposite feature: tune to get less power (but higher speed) using variable air gap.
Fantastic explanation of how these motors work. Thank you!
VERY educational! Thank you for the upload!
Awesome breakdown! Up there with some of the best EE videos!
Awesome video! Great series with Formula E!
thankyou ..... very detailed video and your explained everything in a simple way .... good luck ..... eagerly waiting for the next part of this series
I kinda learned this stuff while using RC trucks, boats, and planes. But this video has now made it all clear, thanks. :D
What about those stickers on the windshield? Do they add power to EVs?
The animation was so helpful. Good video
Great Video, I've really enjoyed the electric car series.
Nice explanation!
finally. this is the type of video i have been waiting for. this is almost nonexistant on youtube
awesome video!
As a recent semi-electric vehicle owner, I appreciate this insight into the tech in my driveway!!
(I say semi because it's a Volt. Electric-only for the first 35-40 miles, then it goes to hybrid mode)
Thanks for the explanation of how an electric motor works!!
I love this series
THIS WAS A GOOD ONE
Very nice!
Could you please make a video about the different types of brake fluids , their pros and cons , and in what type of vehicle they're used? 🤘🏾
Great video, thanks for sharing. I'm not a specialist, but what I understand is that the engine in a Tesla (the brand) is a based on the Tesla (the inventor) engine or induction motor. This kind of engine is not using magnets, but it is using only electromagnetic fields to create the rotation. In your video the rotor consists of magnets, while in an induction motor the rotor contains a set of metal parts that become magnetic by the induction of the magnetic fields of the stator.
Excellent video.
Could you make a liquid cooled electric motor by adding cooling pipes into the stators.and having a separate liquid pump and a battery cooler.
Also Gold wire wrapped around the stator for lower resistance.
Modern electrics already have liquid cooled motors, and gold is not that great of a conductor. Silver is the champion of basic metals, and even then it's only a 7% difference.
@@MsSomeonenew gold is the best conductor of electricity wdym
great video, i like the detail explanation
recently i read about decarbonation the piston and valve using water
can you make the video of proofing this things works and not just an urban myth and explain why?
Awesome videos man. Any chance we could get an Evo IX review?
We tune electric RC cars for RC racing all the time (1/10 scale touring cars). We have speed controllers ("inverter") onboard that can control the motor timing and boost power by almost 50%. The speed controllers advance the timing of the motor based on motor RPM so it dosen't have the torque drop when the motor is at higher RPM. We had these type of speed controllers introduced to us around 8 years ago and when they were, it was a huge improvement to have the tuneability of electric motors. The increase in speed was almost like adding a turbo to an real car's forced induction motor, so the programming was actually called "boost timing" and "turbo timing" for different levels of RPM/throttle position when racing.
The really interesting part is, can I tune it to get better lap times? Especially with multiple eletric motors you can really increase the performance. A lot of stuff can be improved for track racing, just changing the software.
This actually makes a lot of sense. There's a ton of info on the internet on engines and how they work and how to tune them, from basic to advanced subjects, but I don't understand why there's barely any info on how exactly electric motors work. They'll give basic overviews on how motors work, but they're so poor on the details that if they were explaining how engines work they would say, "Fuel goes in, and exhaust comes out. The end."
Also, AC motors now look like piston engines to me. The magnets in the stator being "pistons" and them switching poles is analogous to pistons moving up and down, while the rotor is the crankshaft. This was very informative. EVs still don't hold a candle to ICEs when it comes excitement and user engagement, but you've made them a little more interesting. Forget Elon Musk - you just might be the person to get me interested in EVs.
Yes. But that is overclocking, not tuning.
Hello. I love your videos :) I think, that I have interesting topic for you to make a video. Could you do video about turbocompound technology used for example in Scania trucks? It was also used in some World War II aircrafts. It uses normal turbo and secon one, which does not spin compressor, but transfers power directly to engine shaft.
Why is so rarely found in engines? If it's also regaining power from exhaust gases, why we use turbo rather for compressing air than for spinning engine directly?
Do Aurora AFX slot cars next! Principle is the same and I had great fun taking them apart as a kid.
Switching the windings to a better conductor like platinum would decrease heat generation but then of course the much higher density would increase weight a lot.
Great explanation of the electric drive train, but how does the software complexity and tuning work with additional systems like LSD, traction control, ABS, etc.?
Very good explanation. However, for a motor used in electric car, it is typically not a permanent magnet rotor. It is an induction motor(rotor is just metal bars). The motor produces maximum torque theoretically at its breakdown torque. However, by using invertor (aka VFD Variable frequency drive), an induction motor can run more efficiently and deliver more power at different AC frequency input while save energy.
My heart hurts when i look at electric cars... Turbo and super chargers and sexy car noises are gone... Everyone will be a great drag racer 💔
Hey man.. would be awesome if you did a video on what to look for when converting to electric
I think the main limiting factor of an electric motors output are the insulation properties of the varnish used on the copper cable and the resistance of the copper cable. Class h insulation ( varnish) is good for about 180 degrees. Increase this and more power is possible.
Even though electric motors (or what I'm now gonna call E-Engines) are the most efficient design, they still follow the 2nd law of thermodynamics as do batteries and anything that produces heat wether directly or indirectly. However I'm keen to see what car modding will look like in the next 5-10 yrs or so.
Hi Jason, this is not related to electric cars but I am interested to know the difference in strength and application between 4 lugs and 5 lugs wheels/hubs. The only thing I found from researching is 5 lugs' torque spreads more evenly throughout its surface.
Hopefully you can help shed some light on this.
Thank you!
hey good job :-) could you explain how crdi works?
It's going to be interesting to see how manufactures decide to limit the power tiers up depending on the package u pay for on the model. Like is a Camaro SS going to have a better inverter than an RS? Or will they adjust the rotor stater gap to limit customers from turning up the power
Do a video on the new Mercedes AMG Project One prototype!
The aerodynamic game of the hypercars means they are all starting to look like eachother, explain why car manufacturers eventually hit the limits of design when it comes to pure aerodynamics =)
Can you make a video on setting up a drift car? I know you have made a video like that, but there seems like FD and D1GP set their cars up differently
Doesn't the permanent magnet rotor also limit the torque based on it's field strength and materials used ?
I have weight issues with a 72volt lead acid battery on my bike, should I try to integrate lithos ?
can we modified the electric motor by changing the magnet with the stronger one, the wire, and electric motor swap with the bigger one?
Well this changes my perception of electrics, nice
I think for certain applications, such as drag racing, we will, indeed, see some very exotic electric motors built. BUT.. don't get your hopes up. They will more than likely, be very short term use as they will get hot enough to fuse the windings after a run or two... and may take over an hour to cool between runs. But... it's a start. Soon, very soon we will see 300mph electric drag cars. (pssst... there are a few out there right now)
Make a video about turbo flutter and if its bad for the engine/turbo please
Are there any materials more conductive for copper wires or use more chemicals on battery? Probably this will affect cost and many others but in a theoretical level
Crazy question.....would it be possible to submerge the engine in a conductive fluid that could be used to control the temperature and therefore narrow the gap between the stator and rotor?
This is why I like physics, because I can actually understand some of the stuff.
So is an inverter the electric car version of a rc cars speed controller?
In some of the rc cars you will need to tune the motor if it is a performance racing motor you can adjust the timing to get more rpm or more torque depending on the situation and a cooler running motor will have more power
In the graphic at the beginning the electromagnets remind me of cylinders/pistons. Would that be an appropriate comparison?
Very interesting video! Thanks EE!
Torille!
By the way ordinarily a 1 mm copper cable insulated with pvc is ok for about 10 amps. In an MRI magnet the super conductor cables are 1 mm and cooled by liquid helium ( pretty close to absolute zero) they can carry 1000 amps. Current flow is limited by resistance, so if the motor is close to zero ohms the current is only limited by the internal resistance of the battery.
I expected a bit more from EE. There are a LOT of parameters when it comes to controlling the brushless 3/5/whatever phase motors (power limits, timings, PWM frequency and many more). And tinkering with these parameters can change the power output, efficiency and torque of a motor. Fairly similar to tuning a regular car. Along with battery upgrades (more voltage = more power) you could probably get 50-100% power increase if the thermals allow it
So upgrades would be possible through added cooling units, aftermarket ecu, and better batteries/electrical motors? With this line of thinking I can't help, but think of possibilities of upgrading an electric car much like an R/C Car.
Please do a video explaining hydro pneumatic clutch
Hey what up Jason!
Investing in better stators or rotors couldn't result in best current flow? (e.g. gold or platinum covered stators?)
I don't think that I heard the most important thing - you can pump as much energy in electric motor as you want, provided that you can take away excess heat (LOTS OF IT). And magnets really dislike heat.
With BLDC motors you can tune the voltage supply wave to the nanoseconds, which can certainly help.
How we can select the motor based on the requirement of the vehicle? And how to calculate the the how much distance it can travel with full charge of battery?
Do you know how they improved the Cadillac ELR over the Volt and then again increased the power for the 2016 model? I am really wanting to upgrade my ELR so it's at least as fast as the 2016 model lol.
To the guys that want to know, yeas you could increase the power of a Tesla if you found a way to program the Inverter (or Electronic Speed Controller (ESC) like we call it) to have a higher amperage limit, yes this will produce additional heat and much like the Ludicrous mode reduces the lifespan, this will go even further. Also depending on how the controller is programmed this may cause the wheels to spin from a launch, however it might not increase high speed performance, since at that point the motor may be limited by voltage.
Hello EE, I know this isn't your main topic but, could you make a video "how can motorcycle engines be so small and achieve so much power?" or something like that? Unless you already made some kind of video on "small but powerful" engines that would have similar explanations.
What is the advantage of cooling the batteries before a race
Jason, wondering what your thoughts are regarding EVs, Hybrids and IC given the evacuation from Hurricane IRMA. Folks had hard time finding gasoline. But obviously EVs wouldn't work well either given the lack of range, so Hybrids the way to go?
Only thing that concerns me about EVs and natural disasters is what if an area gets hit hard enough it effects the supercharging stations. How fast can they get those back up and running?
Hybrids and IC are the same. They both need gas, and if the gas station is sold out a day in advance, you're out of luck. With EV, electricity is available even to few minutes before things get bad, so you can charge the night before. Once you're hundred miles out, electricity for fast chargers are available to take you further, but gas may still be sold out.
Gas stations operate using electricity, so if there's no electricity for superchargers, chances are that gas stations won't be dispensing fuel, either.
Fast chargers can charge even if electricity is out? Irma affected more than one area, millions of people were out, hell still are. So if electricity is out, you're not able to charge.
Seems to me a hybrid is the best way to go in this case because you have multiple powering sources. Car in your garage is certainly not sitting on E. Even if it's only half a tank you can drive in order to charge the battery, right? Then the battery takes over and reduces gas demand, thus gives you more range than either an EV or just IC.
Never owned a hybrid but I think that's how it works.
Of course, if people stored some gas to begin with that would be helpful. Some 2 or 5 gallon cans with PRI in there can go a long way to getting out of danger.
Chevy SparkEV ok but what if you're not in a tesla and dont have access to the supercharger network or if you're in an area with little or no charging stations of any sort accessible? At least you can carry extra gas on you in your car... and gas is more readily available generally, though I agree that it selling out during an emergency is a big problem
You should check out the videos on the channel Sweet Project Cars. He does a lot of videos making wear parts on a vehicle last a lifetime. Most of them seem I'm sceptical on, like using 303 aerospace protectant to supposedly make a serpentine belt last "forever." He even told someone it was ok to use the stuff on a timing belt. I think it would make for an interesting video.
I'm no electrical engineer, but would it be possible to use a turbine to produce power at speed? Even though they don't need intakes for a combustion engine, they still need cooling. Would they be able to make use of cooling ducts by putting small wind turbines in them that create some more energy to put back into the drivetrain?
Vidéo about inverter will be cool
I don't know about you guys, but I know can put engine and turbo upgrades for my coil voltic.

Add some timing. i do it to my associated b6 all the time. in fact my advance timing setting are always changing the timing based on rpm to maximize power in any rpm range.
I know alot about combustion engines, but not so much about electric engines. Guess it's a good idea to start learning about them now since i'm becoming a mechanic...
My works too. Used Avasva handbooks and build it with no problems.
How do you compaire the power of an electric motor to an ice motor? I'm thinking of converting a diesel powered 30" boat to elecrtic, but I don't quite know how big an elecrtic motor I should look for...

Question: Can you tune electric cars?
Answer: You can tune them if you can tune them.

Tesla model S uses an induction motor. The motor you explained was a permanent magnet BLDC motor. Can you explain why formula E cars use BLDC while production cars like Model S use induction motors??
The stator coils can be silver instead of copper since silver has more electrical conductivity than copper does. Just replace all the wires with silver and you're good
