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

It a verry good unit for a 10 hp hydro vane compressor soft start. And slow and rapid stop.

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

Después de un par de días funciona correctamente. Se estropeó la bomba de piscina y opte por una trifásica y variador, el cambio es abismal. Arranca suave y puedes regular la velocidad. Fiabilidad del variador... Ya veremos. Buena relación calidad precio. No es un variador de calidad, se nota ya en los plásticos, pero para casa creo que es correcto

Good inverter, it fulfills its function. Only there is no possibility to change the spindle speed with a digital signal.

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.
