Tier-one auto parts supplier Mahle has announced a groundbreaking "superior continuous torque" (SCT) motor for electric vehicles, capable of continuously pounding out more than 90 percent of its peak power without overheating – and it'll work without magnets.
Electric motors, unlike combustion engines, are often specified with separate peak and continuous (or nominal) power ratings. That's because running them flat-out for long periods can generate enough heat to damage components, so manufacturers build in thermal limiting systems that reduce power output down to the continuous level when they start overheating. The difference between the peak and continuous figures reflects the performance of the motor cooling system.
Here are a couple of examples. At the cheaper end of the scale would be something like the e-motor in the Ox Patagonia electric motorcycle. Peaking at 11 kW, it's so badly cooled that it can only handle a continuous 6 kW – 55 percent of the peak power. Energica's fancy new EMCE motor, on the other hand, peaks at 126 kW, but can handle a continuous 110 kW (87 percent of the peak) thanks to a very effective cooling system.
Mahle – a huge German parts supplier consistently posting sales over US$10 billion a year – says its new SCT motor takes things up a notch, with continuous power ratings over 90 percent of the peak. It uses an innovative oil cooling system that draws in oil through a central intake, then uses the centrifugal force of the spinning rotor to pump the oil up and around the stator coils surrounding it. The heat drawn out can be harvested for use elsewhere around the vehicle if required, or extracted through a radiator.

Can you say oil leak? Sure you can. How about an atomized oil leak meets spark providing "spontaneous disassembly" of the motor?
I’m no EV fanboi, but these motors are way cool!
However... that innovative oil cooling system gonna eventually LEAK, as essentially everything containing oil and moving parts and oil seals does. ;-)
Then they will fit perfectly into my Harley and BMW...................
It has been, but indirectly through ultra-low interest rates. Now that rates are rising sharply and the price of new cars has shot up into what used to be the second home price range, I expect sales to collapse along with the affordability of the 7 - 10 year "car mortgages" the dealers have been offering. Meanwhile the used car market will be hit with a glut of repos when the recession bites.
I’m not opposed to them, but the battery store just isn’t there.
Depends on their meaning of ‘new cars in inventory’.
Our Toyota dealership has lots of used cars, and lots of big 4WD Tundras at $90k a shot, but no ‘new’ sedans. At $4 a gallon for gas, they will be there for a while.
The BMW and Mercedes dealerships, owned by the same person as the Toyota, has a good supply of new cars but just the pricey expensive ones........
What we want doesn’t matter, this is about control and power.
No permanent magnets.
We have gone out looking for a new car traveling vehicle over the past couple of months on the weekends, on our motorcycles, when it wasn’t raining.
I don’t want a used vehicle, I want a new one only. Nothing fancy or high powered.
The Dodge dealership has lots of Chargers, Challengers, and 4WD Rams and they also sell Jeeps.
Even the salesmen are apologetic that they haven’t got the inventory they usually have.....................
If you were around in the horse and buggy days you'd say the same about them new-fangled awttymobiles, wouldn't ya?
nice cage!
Autos were better than horses. EV’s are not better that ICE vehicles. As matter of fact ICE vehicles replaced EV’s in 1910. EVs fix a problem that does not exist.
I wonder if F-1 and IMSA are using them on the new “Hypercars”...
If not, they soon will be!
Ze German Motors vill not fail!...........................
ROFL! Oil leaks will feel right at home on my old tractors, too.
By the way, the extra weight of batteries and the high torque of electric motors is not necessarily a bad thing for smallish tractor applications.
But it’ll be a cold day in Europe before electricity totally replaces diesel in ag apps.
If you read the article on their “magnetless” motor tech, it’s not “magnetless,” but it uses electromagnets instead of rare-earth permanent magnets. It’s basically a brushless AC motor scaled up.
It uses an innovative oil cooling system

Sorry, no oil allowed.
I picked up a 2018 jeep right before covid in 2019.
Although I haven’t had any issues, having had a Toyota Tacoma before it I can see in comparison the quality is just not there.
I failed to do my due diligence....if I had known the engines are actually a fiat product it might have swayed my decision to buy it.
My biggest problem is I failed to consider how much I would miss a truck bed.....which as it turns out is a lot.
As long as it is whale oil. I am good with that or maybe baby seal oil.
I owned a Fiat X1/9 once.
Spent more time UNDER IT than IN IT!..................
