VFD 220V 5.5KW 25A 7.5HP Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

I do enjoy the flexibility of the VFD. In my installation I have a mini lathe the DC motor failed so I purchased a 3 phase motor at 1/2 HP.I only have single phase in my shop. I do have a rotary phase converter but I wanted to try this instead. The lathe runs great. No torque issues at any speed. One thing I should note it the unit I purchased is the 5.5K VFD it's all ways better to buy a unit much larger than you need. The programming of the VFD was overwhelming at first then I realized I just needed to learn the basic steps to program and the rest is in the manual. For instance it came preset at 50Hz and I needed 60Hz. After going through everything that said 50Hz I found the setting that allowed me to change it. I believe I will buy another unit for other tools in my shop it's much quieter than a rotary phase converter.

The media could not be loaded. I have a 3 phase 5 HP motor running a hydraulic pump, but I only have a single phase 220v power supply. So, I needed a VFD that could use a 220v single phase power supply to run my motor. The Mollom 7.5hp VFD does just that. My motor purrs like a kitten.I wasn't sure what parameters to use when setting up my VFD, so I reached out to he seller for guidance. I sent them a photo of my motors ID badge and general description of what the motor was powering (a hydraulic pump). They took all that information and sent me a list of parameters. Entering the parameters into the VFD was easy. Once it was wired up and programmed it worked perfectly the very first time I hit the start button. My motor sounds great and the VFD stays nice and cool. Overall I was very happy with their tech support. They made the parameter decision piece very easy. I set the parameters with confidence thanks to them!Price wise, this VFD is a smoking good deal. Brand name VFD that does the same thing costs more than double. This VFD is totally worth the money.Overall, I am a very happy customer.

Aside from the poor instructions on how to wire and program the unit. I couldn't get the thing to even enter programming mode to change values on anything. After about an hour of frustration I just boxed the unit back up and returned it. Ordered a Huanyang after returning this one and had it programmed in less than 5 minutes and had my mill up and running.

I rarely if ever leave reviews, however my experience with this vendor was so positive I had to take the time to do so. I am not an electrician. I am a hobbyist woodworker who happened to luck into a 5HP 3-phase tablesaw that needed to be converted to 1-phase to work in my shop. I purchased this VFD for that purpose knowing I'd have a lot to learn in order to properly wire it. I began a conversation with this seller shortly after placing my order and over the course of several days of back and forth they got me up to speed on what I needed to do to make this work. The device itself is crazy customizable and I really doubt I'd have been able to figure it out on my own. Thank you thank you thank you to the seller for al of your guidance. Highly recommend.

I use it to run my 7.5HP lathe and ive owned dozens of VFD's over the years. This unit seems a bit underpowered and cannot start the machine from a stop. Also after one month of use there are now sparks coming from the unit and ive started the warranty process so I will update this review as that progresses.

I have been using this VFD for about a year or so. I bought it to power a 3 phase motor on a grist mill. I liked the idea of being able to adjust the performance of the motor so I could run the mill at a speed that was appropriate. Customer service is pretty excellent. So if you have any trouble, you can email them and they will respond usually by the next day. Installation is a little challenging as the instructions don't quite explain how to connect single phase into the VFD or how to connect the motor to the VFD. Single phase input is wired in the L an N terminals, but these could be labeled R and T. Wiring to the motor will use the U, V, and W terminals. Wire your motor for the volts you want according to the wiring diagram on the motor. Connect the motor to the VFD. Which wire goes into which terminal slot? I don't know. If it turns backwards for your then you can change the rotation in the VFD settings. You can make all kinds of adjustment to how the motor operates, such as how fast it runs, startup and slowdown speeds, and etc. Overall a good VFD.

This unit has been working well to drive my 3hp 3ph Bridgeport clone (Lagun). I emailed them as per their suggestion for the basic programming I'd need for my specific motor and remote wiring suggestion, and they replied overnight with exactly what I needed. The manual would be huge and cumbersome to try to teach this info, so I really appreciated this support. This unit's output is double the motor requirement (as is suggested with VFD's) and it seems to run happily and cool. If I needed another unit for more equipment I'd buy another from them. (I don't usually write reviews, but I sifted through so many reviews for this particular purchase, I figured I'd chip in on this one)

bought this unit then our 3phase motor had to be replaced got the new motor but cannot get any help from Amazon , and not possible to contact mollom web site comes back not secure.
