Sizing a variable frequency drive

Webb13 okt. 2024 · I have a 1.5 HP 3PH 240V Leeson motor that I want to drive my lathe, but I want to vary the speed. I asked a question on this site about a month ago about how to do that and the recommendation was a variable frequency drive. I'd ideally like to buy a used VFD on ebay to save me some cost and wire it myself. WebbA variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the …
