Onkohan totta ?
YouTube user "MYLOW121363" (hereafter "Mylow") of Chicago has apparently successfully replicated the late Howard Johnson's all-magnet motor, Stonehenge model, that Johnson worked on in the early 1980s to demonstrate to the U.S. Patent Office (patents now expired). Mylow purposely kept his replication as close as possible to Johnson's design -- per the photos, not the patent.
Mylow claims it has run ~26 hours continuous in one setting. His replica begins to turn once the single stator horseshoe (U-shaped) magnet comes close to the rotor magnets on the perimeter of the rotor.
