I have looked high and low for a BLDC controller that will work better. I had a thread on it here. https://www.cnczone.com/forums/spind...78956-cnc.html I actually bought a controller from Anaheim Automation (very nice). The only problem was that I lost some RPM because the controller output 170VDC and the motor wanted 230VDC.
After giving up on that combination, I went back to the Chinesium controller that came with the lathe and got it to work with an interface card. See this thread. https://www.cnczone.com/forums/bench...-sx4-bldc.html This gave me the voltage I needed but the rpm and stability is just not there.
Any help or suggestions you can provide would be appreciated. Thanks.
