Well dang it, now you opened up more questions
What's a good motor design then? low pole count and thin lams?
Just me, or does that not really explain most hub motors?
.. they seem chock full of poles, as many as possible. And laminations... i don't know..
The ebikes.ca simulator shows tremendous amounts of torque and stupidly high continuous power handling running a 16"-10" wheel with a high turn count hub motor. Like a 404 doing 3700w constant, a 5302 doing >3500w constant, a HS3548 doing ~3000w constant, and a 9C 5 turn doing ~2600w constant. all motors producing within 150-250ft-lb of torque. Holy crap.
