Forget about it too expensive
Coreless wire only (cast into kapton or teonex)
No core no eddy currents
Wiley''s no limit liquor

Again: whats the inductance and what controller is suggested as compatible one?

Controller: Suggest Castle or other similar RC unit.
The motor is designed for ducted fans, ultralight copters, and hovercraft. Not much application for ebikes because it rotates too fast; can’t use it as a hub motor.
It is however an interesting concept.

Haha, trololol.
Don't think so, unless you like to see what kind of smoke it is made of.

Right. Any child can sling mud. So what do you suggest Einstein?

The motors have such low inductance, they actually make external inductor sets to go in series with each phase wire just to try to make possible to control.
This has a double wammy against finding a controller for it. Super high pole count means electrical RPM is going to be higher than a Sevcon/Curtis/Kelly can achieve to get it into it's power band, and super low inductance means no RC controller would be capable of any degree of phase current control and will turn into smoke.
It would likely require something along the lines of the KERS motor controllers to use to full potential. Similar to the solid slot motors, which are absolutely rocking motors, but mostly useless because the only things that can run them somewhat effectively cost 10x more than the motor itself.

For ebike parts, don't be a douche, buy from http://www.ebikes.ca or http://www.MethTek.com

I did not suggest anything because I have not heard about suitable controller yet. This is why I ask what they suggest users should run. It looks all good until the inductance part.
