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

I am running mine at 241 volts. Since this is Chinese and designed for 220 volts I was a bit nervous but it seems to handle the higher US voltage at 60 Hertz just fine. The instructions were written by someone who doesn't know English but I'm okay with that.

Fast shipping. Great price. Excellent product. Highly recommended. Will definitely buy again.***************

the 19 year old VFD failed on my lathe. this VFD showed in my search results and the price was a little unbelievable. I know that Vevor has a good return policy, so I ordered it. got it in two days and it was a fast install. I needed to know what breaking resistor to buy and had the answer a few hours after posting the question. it works fine and is in daily production. I recommend this to anyone who knows how to set one up.

buen producto, recomendado. experiencia ya con variadores vevor en fabricas donde están instalados por mi persona

Many reviews stated this vfd doesn't work. But really surpass many of the big brands on the market. If you are not familiar with the vfds, how connect or how operate them, is highly probably you experienced some issue with this kind of devices. The best between the Chinese vfds.

Excelente servicio rápido y bueno y el envío fue rápido ,..,..................Excelente servicio rápido y bueno

Price is awesome!!! Hooked up to a 7 1/2 horsepower motor and it works perfectly. Very easy to setup and program

This did exactly what I needed. It was easy to hook up and runs my milling machine perfectly. I would not hesitate to recommend the to anyone who needs to convert single phase to 3 phase power. That's only one of the many features this device has.

Restoring a '40's vintage lather with a 3 phase motor. A VFD was recommended to me vs. buying a static phase converter. Wiring was simple and allowed me to remove old switch gear. Works great, a little slow to spool up to speed (or down) when starting or stopping lathe but not a deal breaker. Has MANY features not needed with this application. Manual is not great (as has been mentioned before), but again, adequate for my use. Don't have too much run time on it yet, but so far, so good.

I'm impressed with this drive, has more features than I'll use but for the money and what I'm using it for can't beat it. I would recommend this to anyone that needs to run a 3 phase motor on single phase supply power.
