    Not a lot of substance on the technology. We’ve had non permanent magnet motors since Nikola Tesla invented induction motors. They were one of the big driving forces behind making mains voltage 3phase AC.

    We also have switched reluctance motors which use a different operating mechanism than induction, but are still non permanent magnet motors.

    So did they just make a motor using one of these existing, well understood technologies? Or did they come up with something new? This article certainly doesn’t tell us.

    Halve carbon emissions of what, exactly?

        Genius engineer invents AC induction motor, which has no magnets and no brushes!

        That passage does not answer the question of what is being halved.

        I’m can’t go around reading everything, so if a title is already bad, I might not invest into clicking it.

            Yes. Emphasis on the word “particular” product.

            So they’ve made a motor that has half the associated carbon cost of the current tech? If so, then are they claiming to cut carbon emissions in half when all motors have been replaced with theirs? Or… making them has half the cost of making current motors?

            I’m asking what the specific claim of “halving carbon emissions”. Just all of them? Some associated costs? All costs associated with electric motors once they’re all this type? That’s a very vague claim, is my point.

                I’m not being pedantic.

                I knew it would be of a particular motor.

                Thus the title is clickbait, which is why I’ve not clicked it.
