Elon Musk Devises On Tesla’s New Electric Motor, Teases Even Crazier Motor For New Roadster – –


Elon Musk gave details on Tesla’s new electric motor, the carbon-wrapped Plaid motor, and even showcased an even crazier higher-revving version for the new Roadster.

One thing we were hoping for when showing the new Model S at the delivery event last week was more details on the new powertrain technology Tesla developed as part of its Palladium program for the refreshed version. of the electric sedan.

Interestingly, the CEO didn’t dive too deep into the new technology. For example, he only mentioned a brand new battery without going into any new details.

However, he unveiled Tesla’s new carbon-wrapped Plaid motor and discussed some details about the new technology, which allows for smaller, more powerful and more efficient motors:

The motors are small enough to be picked up by one person while still being able to hit insane RPMs:

During the presentation, Musk briefly touched on the fact that this new motor is only possible thanks to a new machine that Tesla has developed to be able to build it.

Yesterday, in a new round of tweets, the CEO explained this machine:

“The fiber is wound on the rotor at high tension. The machine for doing this was manufactured by Tesla Automation. The carbon sleeve must compress the copper rotor or it loosens at low temperature due to differential thermal expansion. Preload is also useful in maintaining precise deviation from the stator.

Musk also developed the advantages of the new engine over its predecessors:

“The main advantage of this is a much stronger EM field compared to a rotor held together by metal (usually high strength steel). Another advantage is that the rotor can reach higher rpm, as the carbon sleeve (most of the time) prevents the copper rotor from expanding due to radial acceleration.

In short, the new carbon-wrapped rotor allows Tesla to push its new engines to the next level of performance.

Also in the same series of tweets, Musk claimed that Tesla’s new engine is “arguably the most advanced engine on Earth,” but he teased that the automaker was working on something even more powerful for the new one. Roadster:

“The carbon-wrapped Plaid engine is arguably the most advanced engine on Earth outside of maybe a lab somewhere. We need to keep some secrets! We have some ideas for further increasing torque and maximum rpm for the new Roadster. Really fun and exciting engineering to come! ”

Previously, Musk had discussed Tesla using the same three-motor powertrain found in the new Model S for the new Roadster, which could achieve better performance based on the smaller form factor, but now it looks like Tesla could improve. powertrain technology. too much.

The CEO recently indicated that the engineering of the new Tesla Roadster will be completed this year in order to go into production in 2022.

Tesla is expected to have new engineered prototypes of the new electric hypercar this summer.
