The biggest problem with the larger KW motors will be supplying it with 55v at 150amps!! That will be one hell of a power supply!! My 15v 80amp supply is pretty beefy and is much smaller than that monster would be. One thing I am currently working on is actually controlling the rpm through Mach3. I’m pretty close but have a few issues that I’m still trying to work out. One major issue will be getting mach3 to initialize the ESC that these motors use. I’m sure a macro in mach3 would work but I haven’t tried that yet either. Any way good luck!
Deleted reply. Dumb idea I had wouldn't work.
