I’ve seen the slightly larger NEMA 17 motor replacement, and the whole spindle assembly replacement, so I’m wondering if anyone has attempted replacing only the current NEMA 17 motor with something much more powerful, like a few hundred watts or beyond. I don’t think anyone makes NEMA 17 BLDC motors beyond about 120W, but with some adapters it should be possible to mount an RC BLDC motors that are cheap and powerful, at a reasonable size and right RPM.
ODrive have some interesting products and information. In the meantime, how far can one push the stock spindle on the Nomad? And at what point would the stepper motors or the rigidity of the machine become the limiting factor?
