New motor technology. Maybe this is what ev needs right now to supplement the lack of battery technology. Most of this article goes over my head, but would love to know what the tech wizards on this site think.

To me, it sounds like more moving parts and trying to look for a problem that doesn't really exist (IMO). However, if it really gives more than 10% better range, that makes it worth trying in the real world.

Interesting. If all claims are work out this would be good. 10% efficiency gain is about all there is to get over today's best motors but it could go a long way toward reducing that top end sag we feel in our bikes. Worth watching. Tesla and others aren't standing still though.

Here’s a more stable URL for the article. Google News messes with things.

My take on this is that there are multiple motor winding stacks (up to 4) and the controller manipulates the configuration of the stacks/windings (the number & posisition of motor poles) to achieve the best operating scenarios for starting, excellerating, cruising, decelerating, etc.
Unless your including the cooling system there shouldn't be anymore moving parts then present day motors (the two motor bearings).
However the controller will be more sophisticated bringing with it a greater chance of failure as likely there will be more components in the controller.
A 10% increase is great but if it comes with the need for fluid coooling it may not be advantageous for all applications.
The holy grail in the advancement in EV's will be the next generation of battery's with 2-3x increase.
EDIT:
Forgot to include that the controller will also configure the motor phase (1, 2, 3, & even 6) for the best output for a given condition/situation.
Also upon watching the video, it appears that some of the the magic occurs in the rotor & thus perhaps commutators would be needed.
