This is my fourth Vevor VFD and I am a true believer. They are great.
This one went on a 1913 Hendey lathe, replacing the Rotophase it came with, along with the reverser and on/off switch. It eliminates the need to change the cone pulley flat belt, with full speed control in the VFD, with all the power you need, as well as reversing.
You can set the exact speed you need for any diameter, material, or cutting tool. No compromises. The deceleration can be set to a dead stop in less than a second. Maybe instantaneous, but I don't know if that's bad for the motor or VFD.
