Totally agree. Drove a model 3 LR about four months ago and it was mind boggling. The torque and acceleration was unlike anything I’ve ever experienced! Unfortunately, I can’t afford any new car currently, but if I could, I’d be getting a Model 3 no doubt! It actually made up my mind to get a computer science degree to get into the EV field.

Your lawnmower can run at full power on its tank of gasoline longer than a Tesla can run at full power. That's the truth. I'm guessing that five minutes at FULL POWER will drain the battery of a Tesla car.

xd

@@philipmiller5036 the truth is electric appliances are the most efficient things in terms of energy comversion and usage WHEN THEY ARE CORDED to grid. Thats why electric lawnmover is superb and electric cars are very inefficient. Battery blocks them and since they still need to first convert energy from grid (1/3 phase, depending on charger) to DC and then from DC to 3phase, there is not only unnecessary level of electronics that are nightmare in maintenance, but also there are a lot of losses.

I assume the other motors smear feces onto the rotor magnet to coax the wheel into turning out of sheer disgust. Note that the feces must be continually lubricated which indicates that piss or vomit could be used in addition

My head hurts.

Basically reduce friction between the magnetic field lines increases efficiency. All achieved by interlocking them by changing the angle.

This is the easy part. Try understanding and improving battery chemistry if you want a real challenge.

apples to oranges to correctly compare would need to account for the efficiency in the production and distribution of the electricity to charge the car.

You have to consider the WTW efficiency to be honest. BEV can be better than ICE but not 94% vs 20%. The electricity to recharge the battery has to be produced in some ways, if it is produced through fossil fuel the WTW efficiency is much Lower. You comparison doesn't have sense because there are different boundary conditions.

@@federe6786 you mis-understood the point of my comment. It was simply to say that the efficiencies of the electric motor cannot be compared to an IC motor at the vehicle level.

@@markhgillett sorry, there is a misunderstanding, my comment was for vortifyne (the person who commented under the video), not for you. I agree with you 👍, we were pratically saying the same thing

@@JohnSmith-uy2jg of course that 70-80% losses include heat

Efficiency of our batteries. Its one thing when you have a AC/DC connection to the wall or some other power supply, and another entirely when you have to count on a battery to live for multiple years of discharging quickly. It was adopted sooner, just not in the "Mass produced" automobile sector.

Stop insinuating that you have intelligence

Yeah, something of the sort. Unfortunately, spark advance did not resolve the issue of Coil magnetic-saturation at high RPMs. That was resolved later with multiplexing multiple Ignition coils. (first it was 2 coils (50% duty cycle) now some cars have one coil per Cylinder.....)

Very good analogy.

@Robert Slackware They don't have 2 levels of CONTACTS. It's all electronic Commutation. and they don't fire on empty cylinders. the EIS simply monitors the firing sequence then triggers the proper coil. By sharing the duty cycle the Coils have time for proper saturation. which was a problem at HIGH Rpms.....

Not at all. Inverter motor simply take the electricity and adjust the frequency. The outlet in your home runs at 60hz. The inverter changes this HZ to whatever it needs. It goes from 1hz to 1khz (top limit would be the maximum rpm the motor can handle). The first DC brushless motor was the gas gauge in vehicles back from the middle 1900s. Yes that is a DC brushless motor.

Not at all like that. The old motor they had would run like that. They had timing advances. This is like running 2 ignition systems both at the same time and blending between them depending on RPM

That's exactly right... a simple yet effective solution which also reduces heat, increasing performance with less chance of demagnetization of the permanent magnets (your know the old adage "kill two birds with a stone").

@@BillAnt I wonder why other companies don’t do this. It’s such a simple way to take on heat but like stated in the video, Toyota doesn’t? Are there downsides to it?

​@@willg125 - Maybe Toyota hasn't watched this video yet to get a clue. lol jk Often decisions come down to cost or other factors.

Imagine what he could have done with access to today's computers, AI, laser cutters, 3d printers and other rapid prototyping tools.

Electric motors already are at the higher end of 9X% efficiency, which is already double the efficiency of combustion engines. It's cool if they get another %, but if you want EVs to get a jump in performance, the batteries, like QuantumScapes new Solid State Battery design, have the most potential.

@@carstekoch The competition for motor improvement doesn't stop at efficiency. Gains in motor power and rpm's will remain ongoing.

@@stevenhill3136 Yes and no. If you desperately want a Single gear EV, maybe with 4 motors one on each wheel, than this is a valid concern, otherwise you can just insert a gearbox and regulate your power and rpms through that. at the cost of weight and maybe space.

@@nextchannelnext8890 I believe you responded to the wrong comment.

@@soundtrancecloud5101 the key answer is that elektromagnetic fields can be split in the "electro" part and the "magnetic" part, the angle between them is 90 degrees, here pops up the translation of the rotor of 45 degrees, here you see the difference between zero-max - zero the 50 degree is just a result of the vector calculation. it is not rocket science, it is more difficult:)

That’s just because it wasn’t perfectly explained and skipped over a lot of key aspects. Even when explaining things to someone who has prior knowledge of a concept, it is extremely important to link the derived graphs, diagrams etc. with what is actually being observed. Starting with a re explanation of the root, in this example the poles of different atoms and how they are generated, and then building up to the bigger picture with their complex magnetic field diagrams. I’ve always found that a lot of education systems suffer from this same issue, where they teach theory that is simple to perform, but don’t delve into why it is that these things are true, meaning most students don’t actually develop understanding and rely on their memory of formulas etc.

You’re in good company; I have a bachelors degree in physics and had to pause and rewind SEVERAL times to wrap my head around this

I only graduated highschool and I understood it all from start to finish no rewinding needed. The concept is simple but the terminology is what most people are missing to understand what's going on here. They are reshaping the fields from the permanent magnets during high speeds to reduce Eddy currents that cause excessive heat. That's what they are demonstrating at 5:30 and 6:45 by placing permanent magnets within the slots in the rotor. Not saying this is cake work to design and build, only that the concept is simple to understand once you know the language.

It's electrical engineering bruh!!! Nothing to do with mechanical! Mechanical engineers don't even know the basics of electrical!! Wtf.

Correct, but a narrative and a hype has to be built. This is what matters nowadays, gossip over fact. One of the most interesting example of technological disinformation since a long time, together with the mighty Halbach Array and Switched Reluctance or any fancy word out-of-context fanboys like. Nothing against Tesla but I cannot understand why such disinformation exists. Regarding the Toyota Prius, that specific design was introduced in... 2004...For researcher/students in e-motors this is a well known study case and reference design, in the past used as benchmark also (can be found in a lot of research paper) . Report of ORNL of 2010 has a lot of info. Some interesting remarks of this design, from a real expert in the field, min. 8 : 20 ukposts.info/have/v-deo/inOGZmirsJ92mps.html

@@NRG1985 I'm really glad he mentioned the design was originated at Toyota (or elsewhere, before as a reference design?). Agree that Tesla (the company) deserves little credit, but gets it in this case anyway, just the opposite of the real Tesla (who got little credit at the time and deserves more now). Arguably, if Learn Engineering had wanted a more accurate, and clickbait-y title, that was still more representative of the linear of the design they could have said "Tesla Stole Toyota's motor????" . uhg.

​@@crashfactory The Toyota 2004 was the first mass market IPM synchronoys traction motor for xEV with such characteristic V-shape arrangement of the magnet. But the IPM V-shape arrangement and in general all the modern IPM designs are studied in academia since the 1980s (lot is deserved to Prof. Thomas Jahns) and used in the industry probably since the 1990s. Toyota was the first car manufacturer to introduce IPM designs in Prius already in the end of 1990s, with a I-shape arrangement which later evolved in 2004 in this particoular V-shape, which the video considers as magical or never seen before. www.icrepq.com/icrepq19/212-19-abad.pdf We are talking about more than 10-20 years ago, not yesterday...this should be mentioned because at the same time AC Propulsion was working with the motor tehcnology which was available and well known at the time, the induction motor: this technology ended up in the GM EV1, their Tzero and licensed for the development of Tesla Roadster. Since Toyota Prius, IPM became a reference design in the "growing" xEV industry and the Toyota IPM V-shape was considered a reference for their motor development. Example of EV IPM designs: Nissan Leaf, GM Volt, BMW i3, Tesla itself, Jaguar i-Pace...basically the majority of players. www.researchgate.net/profile/Di_Han2/publication/300415557/figure/fig2/AS:396982737752065@1471659468515/Torque-speed-curve-of-the-induction-motor-used-in-TESLA-Roadster-Sport-Electric-Motor-5.png Also I have never heard of the specific term IPMSynR, in the field is just called IPM synchronous motor: intrinsically all IPM exploit, with different proportions (it depends by many factors), reluctance mechanism for the torque production. Some design are specifically called PM Assisted SynR when the significantly exploit the reluctance torque (multiple flux barrier layout). These are facts, no engineering gossip.
