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.

RC and most types of Lithium batteries you MUST know your individual cell voltages charging and discharging.
Don't keep them were you cant afford smoke or fire!
Never above 4.2v never below 2.7v EVER!!!

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-Control

Electric Machine Design Videos by Jim Hendershot.

I've taken a course with Jim and see him at conferences every once in a while. He's a great guy and these lectures are a very valuable resource

Hi learning,
The videos won't play. Do you have to join a club?
