Tesla upgrades model S / X with new, more efficient electric motors



Tesla is working on a new electric motor upgrade for Model S and Model X with a more efficient permanent magnet reluctance system based on the Tesla engine developed for model 3.

As we reported earlier this week, Tesla's model S and Model X sales were crashed during the first quarter.

We noted that the expectation of a hardware upgrade and a design update for these vehicles may affect today's needs.

Last year we reported that Tesla is planning an interior design update for the second half of 2019.

Now we have learned that Tesla is also planning a powertrain upgrade for Model S and Model X.

According to sources familiar with the case, Tesla began to include references to new engines for model S and model X in recent software updates.

The new electric motors, the codename & # 39; Raven & # 39 ;, are permanent magnet relay engines, such as those found in model 3.

With model S and model X, Tesla has used AC induction electric motors for years, but The company switched to permanent magnet electric motors when we introduced model 3 back in 201

7.

Tesla's main engine designer, Konstantinos Laskaris, explained the logic behind the flight in an interview with Charged last year:

"It is well known that permanent magnet machines have The advantage of pre-excitation from magnets, therefore you have a certain efficiency advantage for it. Induction machines have perfect flux control and therefore you can optimize efficiency. Both are sensible for one-speed variable speed gearbox as the car's drive units.

As you know, our model 3 now has a permanent magnet machine, because for the performance and efficiency specification, the permanent magnet machine solved our cost minimization and it was optimal for range and performance targets.

Quantitatively, the difference is what drives the future of the machine, and it is a switch between engine cost, range and battery cost that determines which technology will be used in the future. "

The more efficient electric motor contributes to Model 3's impressive range in a more significant way than anyone thinks.

According to people who are familiar with the case, the Model 3 engine can record an efficiency higher than 97% compared to around 93% for model S and model X engine.

The average discrepancy is even more significant in stops and -Go traffic where the model 3 electric motor is much more efficient than Tesla's AC induction motors.

Upgrading the engines with existing battery packs can add up to a few dozen additions

The timing of the electric motor upgrade for Model S and Model X is not quite clear, but it can happen relatively soon, according to people who are familiar with the case.

The upgrade can also come with others hardware upgrades to increase model S and model X charging rates.

Electrek's Take

The new engine-enabled specifications are still on the rise tea, but we expect a decent selection and power outage.

As we reported earlier this week, Tesla Model S / X sales dropped significantly over the last quarter.

This hardware upgrade could definitely help with the sale of the two models. It also comes just before a series of new and competing electric cars hit the market and can help Tesla maintain its competitive advantage against cars such as the Audi e-tron and Porsche Taycan.

We will keep an eye on this project Raven and will report back if we get more information. If you know anything about Tesla's new electric motors, you can reach out via the contact information below.
