An EAA email tipped me off to this press release. I've quoted a small portion of the text below. Of note is the supposed 95% efficiency and it's very low weight per horsepower. At those RPMs a reduction device would be needed though.
LaunchPoint Technologies, Inc. has completed optimization and initial prototyping for a high efficiency, high power density, Halbach array electric motor. With a total weight of only 1.4 pounds, this electric motor produces 7 horsepower at 8400 rpm with 95 percent efficiency. Although the current design is only 6 inches in diameter and less than 1 inch thick, this high power density motor design can be scaled and adapted for larger electric vehicle applications. At 5 horsepower per pound, this electric motor has a higher power density than any other electric motor on the market.
