This kind of a cool article, no so much in my opinion but because of the description of the torture testing that was conducted to prove and improve the motor.

Interesting. Like the idea of long-duration WOT testing, but I'd have thought a long-duration "lugging" test would have been even rougher on the bearings.

Still, nice to see someone designing more for overkill than "just adequate"...
