I can not open the document its ask me to purchase the PDF. I've found a lot of educational modules on YouTube presented by John Hendershot, ill have to give him a shout out for placing the info modules and his experience on there.
I'm learning a lot from what he presents tied together with my engineer modules is giving me an idea of the materials used and purpose, Its is starting to make a lot more sense now lamination thickness for a 50hz machine vs 20khz etc and that end turns are where heat can gather and air is very poor at heat transfer so a boron epoxy on the end turns can increase thermal efficiency, I got a lot to learn but I will enjoy it.
From what I gather a very high frequency motor could be achieved with a bonded carbonyl iron stator, and a carbon fibre rotor with samaruim cobalt 28 perm mags it would have a lower torque density than a neodymium but have very high temperature resistants.
