Hey motor/drive experts- why have the DC motor and drives fallen out of favor, with 3-phase var. speed drive being the go-to system now? Just curious...
20 years ago and more, 3-phase was a rare bird used mostly on the $$$ machines like Oneway, et al. Weekly there were web discussions about salvaging treadmill motors and running them with Minarik drives (similar to how Craft Supplies shipped Woodfast and Vicmarc lathes).
My early 2000s CS-outfitted Vicmarc VL200 shipped with a new Leeson 1.5hp DC and Minarik drive, still working to this day, and if I need it to I can creep down to lower RPMs than the 3-phase system on my new Oneway 1224 can do.
Thanks for the insight and experience.
