Iron free permanent magnet disc motor illustration

14 permanent strong magnets in the rotor alternating north and south pole and 21 3-phase field coils. 14 pole motor, 7 sine cycles per rotation. Disc diameter about 30cm and 1cm thick.

A motor design could be as simple as a sandwich of two coil plates with bearings at their center through which the rotor axle is supported. with two coil plates the forces should be balanced. the spin of the rotor will force air through the coil holes. coil is 2mm wire, 4x4 winding as an example.
Magnets are 50x10mm pucks. the coils could be supported in the inside with a copper or alu ring with a plastic or ceramic insert at one point so it isn't a circuit ring and Lenz resist magnet travel.

The advantage of no iron would be low weight and high efficiency, particularly at low torque cruise which will be key for future vehicles.

Why are there all these weird comments that say "Your Video Is Very Useful Sharing 14 perm.."

they go on to say verbatim what's in the description or title.

Something's fishy on those comments from cenedywong and lupabuatchannel. They seem like automated messages, i've seen their exact same posts on other magnet videos and they say "I really like" then copy the title or description....

62 comments, 200,000 views, someone paid for views/comments from a third-party =)

@LaenPvP yeah the comments did seem a little odd. I figured they were just chinese. but I certainly didn't pay for views. I figure the view count is a result of how all important the thumbnail is for a video's appeal here on youtube

goverment will never let that hapen

@LaenPvP I've wondered about that too, especially on energy videos..good to know the video uploader isn't the perpetrator. You get such rubbish comments in forums too...normally with a link that goes to cheap knockoff shoes.

Maybe they're just so thick that they don't know the spam links won't show up.
