Re: 110v VFD's. Any issues?
I have two 110V .8kw VFDs and they work fine, but I calculate loads for the spindles at 0.1hp or less. My concern was RPM (24K) and higher feed rates for micro mills in aluminum.
I also have one .75kw VFD that supposedly converts from 110V to 220V for a 220V 3phase spindle. I use it with a 220V .8kw spindle and again try to calculate loads at around 0.1hp or less. Works great for me.
Sometimes I will run heavier loads, but the mills scream so loud when I do that it sets my nerves on edge. I try to run light fast cuts for everything I can.
Since I have 220 wired to several places in my shop now I would not design a 3phase spindle machine around 110V unless it was something I was going to sell.
