How Tesla Reinvented The Electric Motor

When Tesla displayed the motor for the Model S plaid, I was blown away at its complexity. Tesla has truly talented engineers.

Bro’s voice is back 😎

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

The depiction of magnetic lines of force that are generated by electrical current (and vice versa) are consistently wrong in all the renderings/animations in this video. Thus, none of the conclusions are correctly led to by them. IOW, this is just marketing talk, not an engineering explanation. Fluff!

He says that a magnetic field is induced in the wire -- err no! You can't have a magnetic field in a conductor. The magnetic field is surrounding the wire.

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

It’s just not Tesla Space without the voice 🙂… welcome back

Wow, so many inaccuracies in this video. You're clearly drunk on the Nikola Tesla Kool-Aid.

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.

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.

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.

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.

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.

"Modern inventors like Elon Musk" LLOOOOOOOOOLLLLL

Did you say that Elon Musk is a modern inventor! Can you give me a list of what he invented?

Those wires and field lines going in the same direction at 3:08 make me uncomfortable, it’s supposed to be perpendicular

Tesla was NOT started by Elon Musk. He bought himself in at a time when Tesla already had a product. The Tesla Roadster.

Well done to Toyota for the development and introduction of the IPM-synRM motor back during 1997.

Explains AC: Video: shows DC electro train power lines Um yes, makes sense

i'm so glad i invested in those robotaxis you spoke of, totally got my money back in a year
