Hello everyone that has a good understanding of electrical engineering. THE STRONGEST MAGNET IN THE WORLD - YouTube 5:36 Why is this technic not used as it would make the motor smaller and could have much more tight windings. My thought is not to have someone assembly this by hand, rather print the sheets with the copper in and stacking them by machine. You would have a motor with more exact field strength as windings don't vary in distance. Tesla method High Efficiency Electric Drive Unit on Vimeo The efficiency of the motor might just be too good already that little better wouldn't change specs a whole lot. Might be better to have lighter wheels to reduce spinning mass. Im I just away on a thinking spree?
