Customer Reviews for VEVOR Variable Frequency Drive, AC 220V Input 4KW Variable Frequency CNC Drive Inverter Converter, VFD 5.5HP 1 or 3 Phase Input, 3 Phase Output, CNC Motor Inverter Converter for Motor Speed Control

These are great for converting 3-phase motors to single-phase, with full speed control and reverse. Just put 2 on a radial-arm drill press, replacing the old contactor box.

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.

I bought this to run my iron worker because I didn’t have 3 phase electric. My shops single phase . The directions are decent. I wish someone would make a video on how to adjust the settings that’s the only confusing part . I need 60HZ but my machine is working on the factory 50hz setting so for now that’s where it’s gonna stay. I had to bypass the factory control board & wire it directly to the motor. Works great so far . A YouTube video on this would be a lot of help but I couldn’t find one for my application. I am happy with it :)

Good Postage, instruction not great but works well.

I haven’t used this extensively yet, but it’s converting a 3 phase 5 horse table saw motor to single phase 240v and doing an awesome job. I wired a paddle switch for easier operation from Powertec and love it! I set up a soft start and electric blade brake, all were super easy to set up.

Excelente variador y con la actualizacion se ve de mejor calidad, hace su trabajo mucho mejor que el anterior.

The inverter is of high quality and is exactly as described. We'll use it in conjunction with the 4 kW 2220V Air Cooled Spindle Motor for a CNC/milling application.

Sono rimasto molto soddisfatto dell‘inverter, lo sarei stato molto di più se avesse avuto il manuale in Italiano ma pazienza, alla fine mi sono arrangiato
