Since finishing my PhD in Engineering, I now spend my time talking to the best engineers in the world about the projects their working on, sharing what I find here on YouTube. This channel focuses on electric power and propulsion technologies that bring us a more efficient and secure energy future, all whilst doing good for the planet. If that sounds interesting, subscribe to keep up to date on this quickly evolving sector! This video focuses on the world's first practical super conducting motor from the company Hinetics. The motor uses some extremely innovative engineering to keep the rotor cold enough for superconductivity, allowing efficiencies well over 99%. I travelled to CES in Vegas to see it in person!

99.5% efficiency🤔 they counted the cooler?
You can see from Noah's hand that he's been playing with strong magnets.
As someone that dabbled with data from cryogenic coolers, I find it hard to believe they managed to get a single stage working fluid cryocooler that can take itself from room temperature to -220 (that is their claim) within 1 week at 250w. Add to that the absurd mass it also has to cool and it just doesn't make any sense. It would make more sense if they had an external system that gets the fluid down to temperature as a pre-spooling procedure and then once the engine is running that 10w actual cooling power can fight against entropy, that one makes sense. But that tiny thing doing a single stage from ambient to -220c? No way in hell.
Superconductors also have a limit to magnetic field strength. It may be higher than traditional copper wire, but it's not infinite.
99.5% efficiency has been third party or independent verified?
Something doesn't quite add up. I think they're over-hyping their actual numbers. They may have some theoretical projections but I think there are engineering challenges they aren't disclosing.
I don't understand why they went the ultra complicated way of cooling the rotor while still having a hot stator ? Wouldn't it be easier to cool the stator coils ?? There's something I am missing in this concept.
Those kevlar spokes are an amazing idea. Made me smile.
How about the bearings? Magnetic? Fluid? Dry? something else?
I was involved in a cryogenic project once, and vacuum pumps were needed to maintain a vacuum as when a vacuum is pulled even metals can tend to "fume off" and thereby ruin the vacuum. This will get worse when the motor isn't running and returns to ambient temperature. Perhaps for this application a "good enough" vacuum, is good enough.
very impressive that they only need 10w of cooling. looks like an exciting device. Maintaining that rotating vacuum seal might be challenging :)
Yasa has 42 kW/kg motor.
What is a typical existing motor's efficiency? Is this a jump from 50% to 99%, or a jump from 95% to 99%. Just trying to understand how big of a leap this is.
Future cars are going to have tiny motors inside each wheel. No gears, no differentials. Just a cable to each wheel. Imagine a car with 4 tiny 50KW motor in each wheel.
All of the example "permanent magnet" rotors were AC induction rotors. No mention of magnetic saturation in the iron which is what actually limits current motors to around 0.5-0.75 Tesla in the air-gap. What's the field strength of this motor in the air-gap? If I remember my electric motor scaling right, motor torque and power scale with the square of the average air gap field. So even 2-3 Tesla in the air-gap would be a huge improvement. The stator coils and case look like they would have a lot of eddy-currents. How are they dealing with that? Similarly, how much of the rotor field extends outside of the motor case? Is it going to cook nearby metal structures while it's running? Do they have plans for an axial flux or "out runner" config as both can better contain the rotor magnetic field.
That guy broke his thumb trying a superconducting high five after their latest break through.
Finally a motor I can combine with my Niling D-sink!
What about a comparison with yasa axial flux motor? Similar power per kg
You really do a great job Ryan - this channel is very enjoyable for those of us drawn to the engineering and science of "things"
this looks like a very complicated solution for a couple of % in efficiency. i know each percent matters in planes, but damn :))
