Customer Reviews for VEVOR VFD 4KW，18A，5HP Variable Frequency Drive for 3-Phase Motor Speed Control

I bought this for my 18/25 mazak lathe which has a two stage 7.5hp motor. I couldn’t use a static phase converter for this type of motor and a rotary phase converter was way to expensive. I am extremely pleased with this vfd. I was a bit skeptical that this would work because the price was so low but it has proven very useful. Thank you Vevor for offering a great product at a reasonable price.

Works as well as any I've seen. The product isn't the smartest VFD on the market but for the price it does a good job. Have it wired to my custom 60T hydraulic press and run a foot switch to it. Probably not worth 5 stars because the housing is a little fragile in my opinion, just low grade plastic to hold those huge wires, but I gave it 5 stars because VEVOR sent me a broken one and their customer service department tried 3 different times to help me fix it (troubleshooting, a new part, and eventually a new one) and I value customer service like that.

Used this to convert a 7.5 3ph Jet lathe to work on a 1ph 50amp circuit. First off, it works great and I was even able to wire in the fwd and reverse to the stock wiring to allow the controls to work as normal. I do wish the instructions were better - finding the actual setting to allow control from digital inputs took some frustrating trial and error, and the settings themselves aren't super clear at times. For the estop, for example, you really want to set the input as External Fault (NC/Normally Closed), which will turn off the motor if the circuit is broken. A small table of settings that should probably be set (various frequencies, motor hp, etc.) would be handy, as well as some details on settings for common use cases like external fwd/reverse/estop inputs. I really can't complain for the price, though!

Great buy, using it to control a 10jp mixer. Overall quality is great. Planing to buy another one soon.

I'm not an electrician, it was difficult to set up. I stayed diligent and was able to program and make the necessary connections. The ability to adjust the ramp up speed and deceleration is far superior to the more simple single to 3 phase converter. Also adjusting the parameters specifically for my motor and application has got to do some good for the life of the motor. I have become a fan over VEVOR, a was cautious at first, but have been happy with their products. The combination of the vfw and the 3 phase air compressor has opened opportunities for me. Thanks Vevor, Chad R

We install this on an iron worker with a press beside it . We switch between the 2 . We had a motor ph that went out and they wanted $1200.00 to rewind the motor. This unit work great. Just wish they had a better manual. it too 2 hr. to install and 3 days to get someone that could understand how to program it

Application on a 3phase compressor worked great. Wish i would have know this earlier. Recommend if you dont have three phase power.

This vfd is great it powers my big air compressor great thanks vevor it's easy to wire it up and is very powerful

Good product

It is a very good product at a reasonable price. I would buy it again!
