Customer Reviews for VEVOR VFD 2.2KW 10A 3HP Variable Frequency Drive for 3-Phase Motor Speed Control

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

The manual could be more detailed on the parameters. The manual does not list all the parameters in the unit so im not sure if they are correctl set. . Im only running a straight 60hz motor with no adjustments to the Hz. For the short time using the VFD it is working perfectly. Much cheaper then buying a rotory phase converter.

Omvormer uitgebreid getest en met de menu functies goed te bedienen en installeren. Wordt hier gebruikt voor een 1,1 kW draaistroommotor op een kolomboor. Heb wel een ster schakeling toegepast omdat in driehoek (delta) de motor te warm wordt. Volgens de manual zou driehoek schakeling mogelijk moeten zijn? Blijft voldoende koppel over om ook grote boren met een rpm van 200 te laten werken. Een technische vraag over de omvormer werd binnen 24 uur behandeld door de klantenservice en verliep over drie afdelingen, was erg onder indruk.

I am surprisingly pleased by this VFD, so much I bought a second one for a backup just in case. This works great on a small milling machine with a 2 HP 3-P motor. The only complaint is the documentation is terrible. They instructions don't explain what programming features actually do. And the nomenclature (that's being nice, some of it is gibberish) is poor. But once you figure it out by experimentation, you get the drift. For the money, this is a nice unit. If you have a coupon or discount code, all the better. I mounted mine in an older tool post grinder box and moved the display out to the cover. I also transferred the controls to a separate box where I used momentary push buttons to control on/off and reverse, but the programming and potentiometer is still on the original display. This unit has surprisingly many ways to farm-out controls to remote switches using the X1 - X6 and SP1-SP2 terminals. Of note, the unit shows a terminal with a 12 VDC output and the manuals says that's 15 VDC but both are incorrect. The output on that B+ is 13.8 VDC, which I use to power a digital hall effect tachometer. Vevor needs to do a better job with the documentation otherwise, I'd recommend this unit for small machines with 3-P motors.

Works great for 3phase testing

If you've never used / programmed a VFD before than you will probably struggle getting this setup. Luckily I was controls engineer right out of college so I had a good idea of what was required. The instructions are complete garage. The translations needs a lot of work. Use the Googler to figure out what what the parameters are. Calling them instructions is a reach but like I mentioned earlier, I had a good idea what was needed to get it running.

So far, the unit has performed as expected. It doesn't have some of the advanced features like the big name brands, such as sensorless vector mode. The real problem is the documentation. Parameters are poorly explained. For example, there is no documentation related to adding an external potentiometer like the max kilo-ohms. Then, P73 and P74 set the "Maximum/Minimum external analog" values. Trial and error let me find values that worked with my pot but it was very much a stab in the dark. Overall, though, it provides the key features of a VFD at a very affordable price.

El equipo al revisarlo no tenía golpes visibles ,aún falta probarlo que esté en buen estado.ya que ayer en la noche que entregaron el paquete se notó que llegó con la caja golpeada y razgada, aunque el equipo no se ve golpeado.pero hay que pedirle a la paquetería sean más cuidadosos.

Ok, this VFD is interesting. I purchased two of them to scale up single-phase residential 240 volt power to three-phase 240 volt power for an older commercial air compressor I got for free. This compressor has two three-phase 1 HP motors on a pump each. I had no choice but to get a set of VFD’s. Knowing just enough about electricity to be dangerous, I decided to make this thing work on my own. I’m an avid DIYer and have wired whole houses on my own, with following electrical inspections of course. So, I researched these and other VFD’s. I decided since these claimed to do what others did for a third the price I decided to take a chance with the less expensive Vevor VFD. Here’s what I found. These things are great for converting single to three phase. That’s straight forward and expected. The huge additional advantage they offered me was their ability to “ramp up” the motors with steadily increasing electrical frequency resulting in a way softer startup than a traditional single-phase motor that has massive electrical draw for the first few seconds of their initial start. This is huge for me since I am off grid, have a 4000w 240v inverter running from eight 6 volt Rolls batteries charged by solar power. Because there are two motors there is a possibility that they may start simultaneously, although I have the pumps’ pressure switches set at different cut-in pressures. Just want to be extra secure knowing should they start up simultaneously, it won’t trip the 40 amp breaker they are both drawing from, or trip the inverter’s internal breaker. Huge advantage and bonus. Now you have the context, here’s the feedback. The instructions are weak at best. They are definitely translated from likely Chinese. It makes it challenging for one to interpret them and to know if one is indeed making the correct connections. If incorrect, it could cause a catastrophic failure. For this reason I took the entire instruction manual, videoed it, uploaded it to Chat GPT and it not only interpreted it, it also gave me clear instructions, both for wiring and for programming these, for my particular application. I wish I could give you all the instructions I created for myself, printed off, and hung right beside the two VFD’s. I’d bet trying to interpret the instructions, translating them with AI, and then creating solid instructions for myself, took me an additional 8-10 hours. No joke. If you’re reading this, it’ll take you about an hour since you’ll know to throw it straight into AI right off the bat. Other than this, I’m happy with these. They’re working flawlessly. They are amazing at ramping up the electrical frequency so I have soft starts on my two pump motors. If you’re ready to interpret the weak instructions, I would definitely recommend.
