Customer Reviews for VEVOR Variable Frequency Drive 220V 4KW 5.5HP CNC Motor Inverter Converter

Exactly as described by the seller, very satisfied

Seller attitude is good, there are questions to answer, delivery speed bar, worth buying oh.

I used this vevor 7.5kw inverter to replace an ebay 7.5kw inverter that would not power my lathe. The vevor inverter works flawlessly and can start my lathe in 1 second and gives me infinite rpms. Very easy to program and use. Way more features that I can ever use. Converts my 220v single phase to 3 phase power. Thank you vevor

Will not power ON.ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss

Exactly as described, I see no reason to buy a used VFD when you can get a brand-new one for less. I wouldn't call a VFD "easy to use", it's a technical tool. The manual gives you all the details you need. Still, if you have never set up a 3-phase motor, you're going to need to do some research. If money was not an object, I'd still buy this VFD. (thinking of buying another)

The instructions are a bit vague but seller responded quickly to questions and drive worked flawlessly

I like it so much, this is a very good product, the only bad thing is to delay at delivery

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 :)

onbky draw back are the instructions. very complicated to program

Used this as a speed control for a hopper. Works well so far. The instruction manual is a little vague. Maybe geared more towards people who install these for a living yet got it wired in and installed and once got the parameters setup it works very well. Hopefully it will last me a while.
