Hi-
I'm in the early phase of research of a canyon carving and HPDE EV swap.
After reading the thread about the Tesla powered Cobra and stator temps being the limiting factor, I'm curious if DLC coating some of the parts in the motor could reduce the friction/heat generated by moving parts in the motor, thus reducing the stator temps.
It's not terribly expensive to have parts DLC coated, and DLC film friction coefficient against steel generally ranges from 0.05-0.20, where as steel on steel is 0.5 to 0.8.
IE could DLC bearings such as these substantively reduce stator temps, or is the heat in the stator not generated by friction? Sorry for the n00b question.
Thanks,
Jason
