New electric car motor
Electric car manufacturer, Magna, have revealed their new E-Motor. It is more power dense, it is more efficient. Its previous motor was 91% efficient.
This is now 93% efficient. It produces 3.3 kilowatts, so around four and a half horsepower per kilogram.
The old motor made only 2 kilowatts per kilogram. In other words, it’s nearly twice as powerful per kilogram of motor weight.
Power Output and RPM
Part of that increase comes from the new motor spinning at 20,000 RPM, rather than the old motor’s 16,000 RPM limit.
Peak power, 250 kilowatt, which is 335 horsepower in a very small size. Compared to an internal combustion engine vehicle, EVs are incredibly efficient.
In fact, they’re about three times more efficient than a gasoline or diesel vehicle. A lot of people think, Well, EVs are so efficient, they can’t really get any better. But actually, that’s not true.
Understanding the Efficiency Gap
There is a new electric motor that weighs only 75 kilograms or just over 150 pounds, but it boasts the best efficiency of any electric motor that has so far been seen.
Now, yes, it’s actually not a huge change in terms of efficiency, but it shows you that actually electric cars, even though they’re amazing today, are continually getting better.
Almost every single year, well, actually not almost, but every single year, we are seeing efficiency improvements.
That’s not just coming from things like new tires or better batteries. It’s coming in ways like changing the way that the electric motor actually functions.
Magna 800 V eDrive Unveiled
The new electric motor has arrived on the market with incredible efficiency, the Magna 800 V eDrive, a lighter and more compact option which has pretty staggering power.
Magna unvalled its new generation 800 V eDrive motors at CES Las Vegas 2024, incorporating several advanced technologies that result in a significant reduction in weight and in size, enhanced performance, and increased autonomy and sustainability.
Size Reduction and Interior Space
Its greater flexibility due to its lightweight design represents a 20% reduction in size compared to Magna’s previous generation Drive.
Now, what this means, you’re going to see electric car interiors continue to get bigger.
The size of the outside of the car won’t change.
Basically, you’ll be looking at a BYD Dolphin or a Tesla Model 3, the outside will be the same, but the interior space will continue to grow and expand.
Battery packs get smaller, motors get smaller, and provide the same power and more efficiency.
This is a huge change, something that the internal combustion world, the motor world, it doesn’t really understand what is actually possible in an electric car.
Advanced Technologies
The Magna 800 eDrive is a key technology and a pioneering advancement in the industry, say a number of experts.
It allows for the eDrive to rotate 90 degrees around the transmission axis , enabling better integration of the system into both the front and rear of the vehicle.
Now, you’re probably thinking, transmission, EVs? They don’t have a transmission well, they do.
Magnathermal Operation Strategy
Another new technology is Magnus High Voltage SIC Power Module, which comes with fewer parts and interfaces, making it much more efficient and effective.
Its efficiency is further enhanced by the new Active Fluid Control AFC System, a reversible electric pump unit for 100% active fluid management.
Magnus electric motor is combined with intelligent functional software called Magnathermal operation strategy.
Benefits of the New E-Drive
This enables on-demand distribution of cooling lubricating oil to the mechanical and electrical components in the motor itself.
This improves the motor’s performance, especially in situations where it’s hot outside or the motor is being accelerated over and over and over.
This motor weighs only 75 kilograms, and it has reduced its dimensions by 20%, which means that you can put them in smaller cars.
Previously, some motors, some electric motors, it was hard to package them. You see your electric car and you think, why exactly is that electric car? Why does it have a long bonnet? It doesn’t make sense, right? Why is the front of that car long? It should be able to be a frunk in there, there’s no frunk it’s filled up with stuff.
Some of these, you see that, right? You think, Hang on a minute. I mean, electric motors are relatively small, aren’t they? But that’s one of the reasons that this is an improvement.
It’s smaller and it allows, therefore, more space in terms of storage capacity, or it allows us to be installed in smaller cars.
It achieves an efficiency exceeding 93.5% in real-world driving, including WLTC and highway.
Internal combustion engine vehicles It’s basically reach a maximum efficiency of around 30%, so it’s three times as efficient as petrol or gasoline or diesel.
It also optimizes its efficient toolbox, significantly improving the car’s speeds and versatility. It’s a single-speed toolbox, of course, like most EVs.
Now, to increase flexibility, ED coupling and parking lock can be incorporated, say, Magna. Now, Magna, of course, they are a contract manufacturer.
They’ve manufactured vehicles for all kinds of German brands. They contract manufacture for Fisca, and for Jaguar, and for BMW.
They’re well known as being a car company that you don’t buy from directly. They basically re-badge the car for you to whatever brand you want it to be.
Great Wall Motors Unveils the New Aura
We remain committed to creating exceptional driving experiences with a supporting and sustainable future, they said.
Our next generation eDrive is the embodiment of that commitment.
Through the seamless integration of our systems, we have managed to reduce our dependence on aluminum and heavy rare earth materials, resulting a significant reduction in CO₂.
Potential Applications Across C, D, and E Segments
During production, by approximately 20% compared to the previous generation E-Drives, Magnus’ new generation E-Drive can be seen as a viable primary or complementary secondary propulsion option with an optional E-D coupling unit for C, D, and E segment cars.
It provides a maximum power of 250 kilowatts, so it’s pretty powerful. That’s probably around about 340 horsepower.
Maximum torque at the shaft is 5,000 newton meters. Of course, to the wheels, that will change With maximum efficiency being more compact and it weighing only 25 kilograms, this electric motor is on another level and promises to significantly change the automotive landscape.
Performance Metrics of the Magna 800 V eDrive
The biggest difference is here, the power to rate weight.
The power to weight ratio for this E-Motor has significantly improved over previous generations.
Future of Electric Motors
In the future, what I think we are going to see is this very small electric motors, probably around about this big, which will provide enormous amounts of power.
It won’t be necessary to have two motors. I mean, now it is for a lot of applications, or will drive, etc.
But there may be a You go single motor and still have a lot of power, even in small cars.
You don’t have to use that power if you don’t want to, but it does enable you to merge quite quickly into traffic if you need to.
And the other option is very small dual electric motors, which will provide huge amounts of power.
Conclusion
As each generation comes, as each new year comes, these electric motors will become more efficient and more powerful.
The future, my friends, is truly staggering. I don’t think anyone can really see where we’re going to end up with this.
But either way, yes, these electric motors will unquestionably kill internal combustion, which just can’t compete on efficiency.
