VFD 1.5KW 2HP 110V 1 Phase Input 3 Phase 0-400HZ Output 20A Variable Frequency Drive Controller Vector Control Inverter Converter for CNC Motor and Spindle

One arrived broken, but when I got the screw out that had come off the board in shipping and screwed it into the broken part of the board, it still worked fine for a few days, then I ended up getting replacements for free, I'd say 5 stars for one, 4 for the other, 4.5 total that I'm upgrading to a 5 because I feel bad for returning them. My favorite thing about these though is that the one phase power connections are clearly labeled, most others don't have that and you have to read half the manual to figure out how to connect them.

Works great with 3-phase motor.

Revived an old washing machine with this

With a wiring change, I am able to turn a cheap harbor freight drill press into a continuously variable speed drill press. Just be careful about the heating of the motor coil, since all VFD will stress out the motor coil. I ended up installing a separate cooling fan on the bottom of the motor. This fan is a spare CPU cooling fan that runs on 12v, which is hooked up to the 12v output of this VFD unit. It is so convenient.

The connections for the input and output are stiff but that is a good thing. I have another vfd that connections would just pop out so this is a nice change of pace. A manual would have been nice even if it was just a link to a pdf I can download but it's running a 1.5hp 3p motor for a lathe and no issues yet. I have a small 120v induction motor fan I may install for additional cooling. If I change anything I'll update the review otherwise it was unnecessary.

I use this to power my grizzly lathe. Very easy to program and run. Terminals are a bit small for my liking, but they will do. Don’t know yet how durable it is time will tell.

It seemed to be awesome until I used it for a few hours. Then it started smoking. I was in the middle of a job and it started acting up giving an error of LU-u which indicates a low input voltage. That was not the case, the voltage checked out fine even under the acceleration load. The manual suggested that I increase the acceleration time, so I bumped it up quite a bit. It still gave the error so I tried a crazy long acceleration time. Then the smoke came out, at that point I gave up. The drive always seemed under powered and now I know why it was so inexpensive. I would stay away from this unit as it seems to not be capable of lasting mor than just a few uses. I will be looking for a more capable unit as the money that I saved can't begin to make up for my wasted time.

Easy to install and set up.
