Ah good thing the batteries are not the heavy part of the system otherwise this would be awkward.
Doomer comment
This motor weighs 12.7 kilograms and has 1000hp. How much does a comparable motor weigh?
There is a 1000 hp tesla with 3 motors that all together weights about 450 killograms, this seems to support your idea until you look at how much the batteries weigh…
The batteries are 550 kilograms to start, and are generally considered to not be big enough. So yeah, great they solved the issue that no EV had (EVs always had lighter motors, and very heavy batteries).
Edit: The 1000 hp telsa is 2200 Kg total, so yeah this would cut out 400 ish Kgs (assuming cooling and inverter and all that) from the total, not nothing but not really a game changer ether. Also 1000 Hp engine is stupid and not needed, maybe if it was a 200 Hp version but then also that would be diminishing returns as this motor would be what 4 kgs?
Put the big battery pack (and maybe an ICE powered generator + fuel) on a trailer for cruising, then have a “ditch trailer and escape” button for that 20 mile sprint at the end of the trip.
Ah, yes. I too enjoy staging my road tripping vehicle like an interplanetary rocket.
Bonus: you can always circle back and pick up the recharge pack, and if you put solar cells on top it can trickle in a (tiny) extra charge when you’re away. More practical: plug it into the grid for slow charging of your big batteries while you zip around town in your lightweight configuration.
Imagine if you called the trailer your ‘house’ and left it in the one place all the time!
A really small house can hold 50 gallons of diesel and a generator, be towed to a filling station, and follow you thousands of miles…
If you want a 200 mile round-trip limited EV that you always charge at home, you can buy those today from all kinds of sellers.
More boosters!
~20% weight reduction for a total vehicle weight isn’t small change. Plus batteries will continue to improve as well. Do you just get off on being negative?
Yeah, I’m not sure how they concluded in their edit that 400kg is not a lot to shed.
The gains compound a bit too, 20 percent less weight equals proportionally less battery capacity required to shift the now-lighter vehicle from point A to point B.
So then you can cut the size of the battery while maintaining the same range, and that’s where you start to get significant overall weight and cost savings.
Hell just replace the former motor weight with battery and you’ve almost doubled the range. If China ever mass produces solid state batteries, double it again.
Texas divorce.
Making the motor lighter gives weight allowance for the onboard BESS. This could allow more batteries to be installed on the same car, increasing range and power/torque, so long as the volume of the car allows that same BESS increase.
It’s still good progress. I don’t understand your POV where we must focus on the BESS first and make that more efficient, both in terms of weight, volume, power, and energy, then move on to other things.
We can do that in parallel and see faster improvements.
How much torque though? HP is nice but power is in the torque as much if not more than the voltage(HP)
Electrics produce maximum torque at 0 rpm …
The voltage/hp comparison there doesn’t really fit.
Power is in watts or horsepower. You multiply the torque with the RPM and a scaling factor to get power.
A higher voltage system could probably be expected to produce more torque and power from the same size motor, but a lot depends on the design of the motor.
Then to answer “how much torque though,” I haven’t looked into it but electric motors have a very nice torque curve across the RPM range. If a motor made all that power with low torque, then it must spin at super high RPM and need to be geared down.
That motor doesn’t look like it has enough mass to properly make enough torque to drive the weight of a car even if said car it made entirely of carbon fiber
Totally, and I think that’s why they thought it was worth a press release. In the article they go right to how they’re setting a new power density record with this design.
Electric motors are just really power dense. The article says they managed a short term peak of 1,000 hp with that little flat 12.7kg motor and the continuous output could still be half that.
Just the cooling must be crazy.
Out of curiosity I looked up something comparable. It looks like high-performance integrated drive units that have other stuff like the single-speed gearbox, differential, and inverter are still only in the dozens of kg.
I was going to shit all over this thing, but if it can do ~500hp continuously that’s awesome. Wonder what kind of efficiency it has and what the cooling requirements are. That low weight puts us back into unsprung wheel motor territory, especially if it scales down well.
Oh man, continuous 500hp, 1k short burst at each wheel. I think my car caught fire just thinking about it…
Every time I get a faster car I need better tyres so the wheels never spin… The fuck kind of tyres would I need to stop 1000hp at each wheel spinning?
Just have the marketing department call them “Full Self Sticking” and then they literally can’t lose grip.
Engineering explained did a video on something similar with the 3000hp Chinese hypercar, and his conclusion was that you’d need to be going something like 175mph (280kph) to be able to use full power without spinning the tires.
Thousands of horsepower in a car is a terrifying amount of power.
Once I figured out it was an axial flux prototype motor this whole article made sense.
Nerd
Until someone tests it independently, this should be considered BS.
I’ll give them some credence based on the cars their motors are already used in and the fact that their parent company is Mercedes-Benz. Doesn’t look like they’re a bunch of grifters seeking investment.
I suppose, but I’m skeptical of car manufacturer claims, too, until independent testing is done.
I hope this is real and think it’s awesome, but will wait to see if they exaggerated.
Well, the peak output is a useless number, that’s just record chasing. I think the continuous output is the number we should be looking at. That is a bit more believable and also started in the article that that number is an estimate for now.
So IMO they’re not making any wild claims. There’s “we measured this huge output for a short burst” and “we think that over a long period, it can do this slightly smaller, but still impressive number, but it needs to be verified”
Will be cool to find out if the continuous output is close to their estimate of course, but even if it’s lower, it’s still impressive by virtue of the super low weight.
28 pounds = 12.7kg, for those wondering.
But, how much is that in baby elephants?
Roughly a tenth of a baby elephant, or around two round trips of your neurons on a single line reaching the moon
Bro got that galaxy brain. Average is about 1.4 kgs, or roughly .5% of a giraffe for you standard pedants.
It’s the lead I eat every day. Helps keep my brain heavy and smooth
cant wait for corporations to crush the competition with some bullshit yet again and then complain that we’re at peak EV tech anyway
The previous version is already in the Temerario. This is more of an evolution of an existing design.
1000 hp = 0.75 MW. If 98% efficient that’s 15KW of heat dissipation Sounds like a subsystem bigger than the motor.
Yep, I noticed that, you’re right. And that’s near-miraculous efficiency. The maker’s website sez: “YASA also estimates that its all-important continuous power will be in the region of 350kW-400kW (469bhp-536bhp).” It also sez: "To achieve a 750kW short-term peak rating and a density of 59kW/kg … " Devi’ls in the details … The image on the ‘superblondie’ page shows A LOT of cooling built into whatever metal that is: https://supercarblondie.com/wp-content/uploads/YASA-tiny-electric-motor.webp
Sez. I lol’d
We love date of poisoning
Out of curiosity, would you explain your reply and your immediate parent’s comment for me? “Sez” - a bit old but didn’t seem too weird, but then: “date of poisoning” - are you implying an LLM wrote that and “sez” has something to do with pinpointing some poisoning of the model?
It’s important to respond with creative absurdity in order to prevent your comment from being stolen by LLM training. Almost as important as eating at least six rocks every day.
Ah, okay, I understand now. Rocks are nutritious—and whisker pants.
Sure!
I can’t speak for the original commenter, but many here on Lemmy will type in unconventional ways so that if the instance gets scooped up by bots and used to train AI the data is harmful instead of beneficial.
I don’t know if it actually has an impact, but it can be fun to participate in data poisoning as an act of subtle resistance.
I believe the OC might have typed sez not because he is a bot, but rather to sabotage bots down the line. Maybe he just did it to save a letter.
EV motors are already over 90% efficient. They don’t piss away evergy as heat like ICE, where about 40% of the gas is wasted as heat and noise.
300-400kW continuously should be the headline. Thats impressive. Lots of motors can try and make 1000hp if you feed them enough voltage but only for a split second before they overheat and burn out. I wonder how long it can do this 1000HP.
“YASA” sounds like a mashup between YMCA and NASA. Even their logo looks like the Y’s.
YMCA NASA colab would’ve been lit though
I’m gonna slap one on my fixie.
Having a powerful motor is nice, but you still have to power it.
Easy! Just make this:
With this:
I’m gonna slap two on my fixie.
Electric cars are already awesome but they’re just getting started. In a few years an ICE car will look like even more of a pathetic fossil (pun intended) than it does today.
Going to take more than a few years to turn this around. I highly doubt I will be able to afford a new EV to replace our 2002, 2004 and 2014 vehicles.
holy shit
This, in a folding, commuter e-bike.
*guns throttle* Tires and tube liquify, blast apart, rim rapidly grinds to nothing against the pavement, spokes rocket in all directions. Onlookers remark: “pretty cool way to go out…” And then give the 🤘 hand gesture
