VFD Vector 1/3-Phase 220v to 3-Phase Converter, for (≤5.5KW Motor) Speed Control (GT Series-7.5KW,10HP Model)

First I bought the 4.0kW to supply an old Bridgeport. It has performed flawlessly right from the start, at this time 15 months later. Five stars for that one.After that initial positive experience, I bought the 7.5kW to supply an even older lathe. My mistake was ordering it months in advance of when I knew I'd have the time to install it, so now Amazon support has long expired. This second one does not power up, at all. Error codes? It does not even turn on, no lights, no output, nothing. Is it possible I installed it incorrectly? Maybe, but I installed the first one perfectly, and the second one the same way. Tested on different circuit, still nothing. Zero stars for this one, so we're averaging 2.5 stars now.The company claims great support for a year after the sale, and I've read of some positive experiences. It's been a couple days now with no response whatsoever, so now I'm dropping it to an even Two stars, and ordering a new alternative from a competitor. Since the installation is all ready to go now, I'll know if the next one functions immediately upon delivery, solidly inside Amazon's support window.UPDATE: It took several days to get a service response, but after only a couple exchanges, they volunteered to replace the faulty unit. The replacement works perfectly.

I used this to power an old 10Hp metal turning lathe. We don't have 3 phase power in our garage and I didn't want to get a phase converter. This VFD was easy to set up, cheaper to buy than a phase converter, and made the machine safer to operate. I am only running the lathe at 60Hz for now, but tested the variable speed and it works great. Nice and smooth. I may be back for another VFD once I get my hands on a milling machine.

I have 4 of these VFDs of various sizes running different pieces of equipment around my shop, and I'm extremely happy with how they have performed. No issues to date, the oldest is probably 4 or 5 years and I might have to replace the fan.Also I'm very happy the newest ones only run the fans when the equipment is running and automatically turn off after a minute of stopping the machine.The manual can be difficult to understand but there are numerous YouTube videos to help you get them setup. If you are in need of running a 3 phase motor on single phase these are a no brainer, and make operation a lot more pleasant with soft start of motors, variable speed control (while maintaining torque). I would keep these in the machines at this point even if I had 3 phase power.

Strong inverter. Used 10 HP for our 5 HP motor (mill) - best fit. Excellent customer care. Spoke each day (would take a day to respond as we are in Canada) but received detailed messages and videos so we could fine tune our needs.

I bought this to convert single phase to three phase to run a lathe. Hooked up per the instructions. Set the motor parameters and changed all of the frequency settings to 60hz. Everything worked perfectly for a beautiful 5 minutes, then click, it shutoff, no display and reading 115v single phase on all output legs all the time. Something internal gave up.
