1887 is most definely not "the early stages of The Industrial Revolution". Most scholars suggest that the Industrial Revolution was between 1750 and 1850. Mechanisation, steam engines and telegraphy played a part in the American Civil War which was 1861-1865. The "early stages" of the Industrial Revolution is categoriesed by water wheels, cotton mills and standardisations

[@aerohk]

1887+ is the beginning of the electrification era

[@nufosmatic]

The reason that Westinghouse succeeded with AC and Tesla over Edison and DC was that he had Steinmetz to make mathematical sense out of it. Charles Proteus Steinmetz (is that a kuel name, or what?) was able to understand the AC systems that Tesla intuitively built and create tools for the analysis of synchronous AC systems. AC analysis, also known as Steinmetz Analysis by people who don't care to repeat history, allows you to predict the losses through a network of connections and design transformers to lessen these losses in a large system.

[@HolographicThoughts]

Yikes, the comments section knows more about EM than the video script. While the oblivious are like "thanks for misinforming me so clearly". 😂

[@ChildSpaceMethod]

Great presentation. Years ago I translated sales materials about Mitsubishi Electric's traction motors for electric trains, elevators, etc. Now I understand them much better! Interestingly, the Japanese engineers calculated that for a new subway line in Osaka, it would be cheaper to "unroll" the electric motor, with a flat pad of coils on the train (the rotor) and, on the tracks, a thick flat horizontal steel plate called a "reaction plate" replacing the stator. Despite all the extra steel needed for the reaction plate, the lower riding cars from this design saved on tunneling costs.

[@TheTeslaSpace]

That’s really interesting. High tech electric trains are a subject I’d love to learn more about, they’re very cool

[@evaluateanalysis7974]

"Interestingly..." That's a linear induction motor. Aluminium would be better for the stationary plate.

[@MikkoRantalainen]

2:20 I think it would have been good to mention that you could transmit lots of power using DC transmission network, too. The problem with DC network is that when you need to step down the voltage, you cannot do it with a static pair of coils and some non-movable iron (which is all you need for AC transformer - zero moving parts, zero logic, zero computers) but you need active components which increase the cost a lot. Multiply that with all the transformers you can see around and you can quickly figure out why AC is used.

[@valentinsacco]

In asynchronous motors, the stator magnetic field and the rotor magnetic field rotate at the same speed, it is a mistake to say that the rotor magnetic field rotates at the speed of the rotor. The difference in speed between that of the magnetic field produced by the rotor and the rotor itself is called displacement speed.

@@kazedcat For one, the magnetic field generated by a current (of either + or - charge) has lines of force perpendicular to the current's direction.

Secondly, fields in an electric motor have no relation to the constant 60Hz frequency of power lines. This video shows a complete lack of technical knowledge. It's a puff piece.

[@brylozketrzyn]

AC motor was NOT invented by Tesla. It is popular myth that everyone keeps repeating. Two phase induction motor was invented by Galileo Ferraris. Tesla was hired by Westinghouse (who already was working on own AC system to avoid royalties) to invent distinct AC motor. Both mentioned were enought to get a patent but both had similar issues - low power output. Ferraris motor was refined by Dobrowolski (kinda successfully, because it had 100HP instead of a quarter) and two years later Westinghouse had his engineer refine Tesla wirewound one.

Much of the pleasure of driving a Tesla comes from the high torque and instant acceleration of its rare earth motors. These materials can of course be recycled as the number of EVs reaches its peak, just as can its aluminum body and internal aluminum castings, and the materials in its batteries, so "used" does not mean "consumed" like petroleum products burned as fuel. If Tesla, or any other manufacturer, wants to make EVs that are as slow and unresponsive and inefficient as today's 4-cyl ICE clunkers, then, no sale, for me.

[@TheTeslaSpace]

I imagine the usefulness of the motors will outlast the usefulness of the cars in many cases. Will be interesting to see how they go about recycling/repurposing this kind of thing.

[@eddiegardner8232]

Suppose you have for reason of slow sales, a reduced profit and reduced cash flow. IF you start making "robotaxis", whatever that turns out to be, you not only have the startup costs of producing a new kind of car, you also are wrapping $20-30,000 around each one you send out the door, because they are not being SOLD, they belong to the company. That is a very negative cash flow, that "might" eventually produce an income stream at some point in the future, if people want to ride around in taxis a lot more than they do already, in taxis, Ubers, and Lyfts.

[@kainhall]

rare earth magnets are not rare.... and are not special my 10 dollar remote control car from the late 90s had "rare earth" magnets.... . also... ICE cars are made of the exact same materials.... yet they dont get recycled as its very hard to separate the plastics, metals, ETC from each other this means... Telsa isnt going to recycle either . they are already loosing money and had to lay off like 40% of the staff.... so, again, their is NO DAMN WAY they will take that big of a hit just to recycle cars... . . also... electric motors DO have good off the line torque this is due to "field slip" . but at high speeds.... it looses HP/torque from 0-60 its fast AF from 60 to 120 is quite slow (my 160HP 99 buick century can keep up from 90 to 120) . and because of that lack of field slip.... the motor becomes less efficient to the point that a gas engine at speeds over ~90mph is actually producing LESS carbon emissions . yes... tesla has carbon emissions (its just at the power plant... instead of the exhaust pipe) but out of sight, out of mind..... keep saying your car has "zero emissions".... its GREAT marketing!!

[@barnowl6807]

Ferrite is a good possibility despite it's disadvantage of being brittle and of relatively low flux density. First, Tesla has developed the motor with a very tightly constrained rotor. That would take care of brittle. Flux density is pretty well fixed by the material, but the volume of material would make up for much of this problem. And all of it workable because of the constrained rotor. And -- it would cost a lot less than super magnets.

[@jimf2525]

You have the wrong orientation for the magnetic field. It’s circles a wire, it doesn’t go out the ends of the wire.

[@quantumleap359]

Another way to eliminate using rare earth magnetic materials is to use an externally powered wound rotor. The rotor is similar to the rotor in an automotive alternator, where the rotor coils are energized through a direct current sent to them via slip rings and brushes. Although the slip rings and brushes comprise a wear element, the efficiency of a wound rotor and its available torque overrides the effect of having a wearing part. We will see if this tech will prevail and become standardized.

[@gsmollin2]

I remember being surprised that Tesla used an induction motor in model X. Then it occurred to me that they couldn't afford rare-earth magnets in a consumer product, and I understood the choice of name for the car.

[@TheDavidlloydjones]

It was not Tesla's invention: Tesla, occupying a bar stool in a Fifth Avenue hotel, did press support for Westinghouse -- who also didn't invent AC. Westinghouse was a genuine, and technically correct, developer. Tesla was a pushy promoter. AC was invented by Faraday, among others, fifty years earlier than the Westinghouse-Edison wars -- in which Tesla was a trivial figure.

[@makeit2132]

@@TheDavidlloydjones Yes, Faraday is by far the true genius here. With the discovery of induction he gave birth to AC. However, the invention of the multiphase AC generator/motor is attributed to Tesla because he patent it (he likely stole the idea from another Italian). On the other hand, when it comes to AC vs DC, the battle was between Westinghouse (personal hero of that period) and Edison. He put the money and took the risk to buy Tesla's patent and increased the efficiency of its initial design (with massive help form his employees). This and his skill as a business man allowed him to win the Chicago fair and light up the world. My point was that out of this list of names... Tesla was the least relevant technologist and people only remember him because of his showmanship and mainly because JP Morgan used him in an attempt to erase Westinghouse out of history since they lost massively by backing Edison and DC.

Uhm... NO... the alternating of AC current is NOT directional. AC refers to the oscillation between a positive and negative extreme of a single direction sine wave of potential energy. IF AC referred to a DIRECTIONAL reversal you would get NOTHING as the directional flip would cancel out the previous state and NOTHING WOULD "FLOW"... and let us not forget that we have a HOT (black) wire and a NEUTRAL (white) wire, with an optional shunt to ground, in basic AC circuits rather than TWO HOT wires in single phase. Given the basics of AC current are grossly misunderstood here, I am bailing at this point as anything built on incorrect foundational information is, by default, going to be incorrect...

Permanent magnet motors and synchronous reluctance motors have been around for decades and therefore Tesla had nothing to "Re-Invent" they just took advantage of designs that had been developed for robotics and automation devices. Also you keep referring to induction motors as having a rotor made of aluminum bars formed into a cylindrical 'squirrel cage'. What you fail to mention is that the aluminum bars are pressure die cast into a 'laminated iron rotor' which is necessary since any 'air gap' will reduce the magnetic flux density which will cause lower power/torque and loss of efficiency in the motor. The laminations are electrically insulated from other laminations to prevent eddy current losses in iron rotor and stator. There are also 'Switched Reluctance' motors that have efficiencies similar to permanent magnet motors but SR motors don't need any magnets on the rotor. They do have vibration and noise issues however and more design improvements need to be made before they are usable in automobile power applications.

Actually, Tesla never invented the 3-phase induction motor or balanced long distance AC power transmission.

The invention of the balanced 3-phase induction motor and power transmission was done by AEG in Germany, but was patent trolled in the US. Tesla never invented the transformers either - that was done by his employer brilliant George Westinghouse who was introvert and didn't need the personal publicity that Tesla desired.

At 3:10, the animation is incorrect. If current flows left-to-right in the figure, the magnetic lines-of-force go in circles around the conductor. You don't get a N and S pole, as if the conductor were a bar magnet. I sure hope Tesla engineers didn't make this video.

[@educationlife9363]

Agreed 👍

[@spencerlarson9357]

His voice is normal again! Was it a different mic setting?

[@jnb8918]

At 9:55, this guy don't know (or at least can't explain correctly) what back EMF is... He talk about back EMF like it is a mechanical or electromagnetic force, but it is not. Back EMF is a reverse VOLTAGE. ElectroMotive Force is a force acting on electrons, this is indeed a VOLTAGE. Not a mechanical force in the motor... And there is many other errors everywhere in this video.

great video, thanks

[@NicholasNerios]

I can't wait until we get the Wardenclyffe Tesla Tower, wireless charged EV planes and electromagnetic cars.

[@garryclelland4481]

dont forget the rarely talked about "Nevergodone Wallet Mk1 "

[@jimf2525]

Look up iron nitride magnets for the answer.

[@bingosunnoon9341]

You talking about ferritic magnets?

[@adrianpbaxter4071]

Outstanding!

[@SerenityChamber]

I love your videos! Keep it up

[@timvlogtv512]

Would those ac motors be considered as a "brushless motor"?

[@Smartiezs]

hey look it's the second roadster, coming right from the factory. it is 2017 right?

[@elinys2843]

What would the world have looked like if this motor had beaten the ice engine.

[@TheTeslaSpace]

A lot easier to see without all the smog in the air, and a lot cleaner without the all the soot covering everything. Would be nice.

[@gmeister03]

Better thought is where would the world would be had energy storage tech not stalled

[@makeit2132]

The electric motor has beaten the ICE engine (I hope you are not using a kerosene fridge or washing machine)... but batteries are quite far from beating the fuel tank yet.

[@chrisb.travelin544]

Excellent content yet again.

[@kieronmarshall2658]

no because once something has been invented it can never be invented again. one can improve or adapt something that's been invented.

[@bikepacker9850]

An induction motor cannot be used in reverse to generate electricity...

[@bohicajohnson7203]

Early days of the Industrial Revolution? 1750?

[@ScottySkilz1]

couldn't you throw more alternators and use the access energy to power the car for longer distances?

[@momo79nono]

why we can use electric magnetic rotor like car alternator

[@manivardhan7588]

I didn't understand what they truly reinvented here? Everything is already invented before 😢

[@mcarrusa]

Y’all look like you haven’t seen the “Retro Encabulator” video, and it shows. 😂

[@mattdaddy_888]

Truth be told most tesla fan boys know nouthing about cars or engines or electric motors. There not not car guys. There tech enthusiasts.

[@ASDasdSDsadASD-nc7lf]

The conclusions at the end of the video are preposterous.

[@jmt979]

Industrial Revolution was from 1760 to 1840. You might want to update your info at the beginning. Otherwise great video but people don’t fact check anymore and being wrong in a video, especially a good one like this, is damaging. Also no such thing as centrifugal force. It is Centripetal force. What you are referring to is the Normal Force.

[@hurle0409]

You can't generate electricity using induction motor. You need permanent magnet motor.

wow superb
