Cozyel AC 220V/0.75kw 1HP Variable Frequency Drive, 5A VFD Inverter Single-Phase to 3-Phase Frequency Converter for Spindle Motor Speed Control

So far just using this to simulate 3 phase AC for engineering. It works well without a load. This review is not about running a motor. I’m not sure I would use for that. It’s small and can’t imagine it would last long running a real motor. For me $50 is an amazing value to test and just for engineering projects. So I bought another. The instructions not bad could use a bit better wording. I have not tried Modbus control yet. But plan to soon.

It's like others have said. Instructions are worthless. Special features? Who knows. Power on a 3 phase motor and easily adjust the speed? Absolutely. It's cheap. It's light. It works.

Used this on an old lathe. Once wired it worked great. Have a good understand of electrics. Mines not the greatest, but watched a couple videos on a similar VFD. Allows great adjustability of an old motor that was a constant 1725 rpm motor in its day. Great unit!

YOU CAN WIRE IT CORRECTLY, AND YOU CAN MAKE THE MOTOR WORK. THAT IS ALL.... TURN ON/OFF, AND ADJUST SPEED FROM THE FACE OF THE UNIT. HOWEVER, DO NOT EXPECT TO DO ANY PROGRAMING! IMPOSSIBLE TO FIGURE OUT PROGRAMMING ON YOUR OWN, AND NO DIRECTIONS FOR PROGRAMING IN MANUAL OR ONLINE.

works perfectly on a 1/3 and 1/4 HP 22v 3 phase motor.

I set the RPM limit to 99Hz, up from the default 50, because why not. After turning it on and off quickly once, it gave up the ghost. E.02 on trying anything. Looks like something internal was damaged. Loved it while it was running. Took a while to ship a replacement.

Perfect little VFD for 1 HP or less. I like that it can be mounted on the door of the electrical box. The control connections detach from the unit so they are easy to wire. Instructions and programability are what you would expect from a Chinese unit. I have a few of them with external switch control .

Impressive out of the box. If it functions as good as it looks, I'll give it 5 Stars
