Re: Resources
Great info papers on motor design.
I gota believe that there is much room for improvement in a Crystalyte X5, now I can educate myself even more to see what needs to be done to make an X5 lighter and more powerful
Thanks for posting all this.
Cant wait to get some free time to read it.

Re: Resources
IMO, Shane Colton's 2010 Master's thesis (which discusses the scooter motors and then goes on to present an axial-flux motor design, as case studies) is even better: http://www.scribd.com/doc/32379147/Desi ... or-ControlMiles wrote:Shane Colton's paper on an MIT scooter motor educational workshop.
