Magnetic Gear Motors?

This is a new kind of machine, but not a new idea. It is “the most compact highest torque-thrust electric machine ever made”. It could solve the hill climbing problem of direct drive hub-motors by producing a much wider usable speed range; but no one seems to know if this is going to work like they say it will. Magnetic gearing?

It seems to me that this tech would be really well suited to a crank drive since you can achieve great torque output while still being efficient at low speeds!


The bottom line is that their 1,000 watt PDD's with a 500 rpm output weigh 6 kilo's! (13.22 lbs) a bit much for most “weight weenys”, but not too bad for a large cargo bike!
