HET electric motor massively boosts power, torque and efficiency, reduces weight

--- Quote ---A Texas-based startup has raised US$4.5 million in seed funding to develop and commercialize a remarkable electric motor technology. The father/son team claims the design can massively reduce the size and complexity of electric powertrains while also significantly boosting efficiency and doubling the torque output.

Legit or dodgy?

HackedFridgeMagnet:
umm... idk

One warning sign, they mention "disruptive technology" in their first sentence. 

Also wouldn't "power density" the same thing as "total output of any permanent magnet motor of the same size" in this case?


--- Quote ---The result, says Linear Labs, is a truly remarkable motor that produces two to five times the torque density, at least three times the power density and at least twice the total output of any permanent magnet motor of the same size

One might be power/weight and the other power/volume.

james_s:
I'm not sure how you could "massively" boost efficiency of electric motors, it's not uncommon to get 85% or better in smaller motors and large motors can be in the mid 90s. Electric motors are already one of the more efficient devices out there.

Psi:
I wonder how much it shares in common with this one that was in the news recently.
Also claiming to vastly improve motor efficiency
