Huanyang VFD,Single to 3 Phase,Variable Frequency Drive,3kW 4HP 220V-230V Input/Output AC 13A for Motor/Spindle Speed Control,HY Series

I have 4 of these operating pumps 24/7 365 since 2020. They are in a hot environment, so I have a 4" computer style fan laying on top of each controller drawing up to assist with heat management. The internal fan is probably not up to this task once the heat sinks become dirty after a year or two. Heat kills silicon, so it is well worth the extra $10 investment for an external fan. I am using external control of speed and also using another input as a safety fallback to keep the pumps idling at 20hz in the case of a blockage or other water issue. Make sure they are mounted vertically (as shown in the product photo) for proper airflow.

Works well on Bridgeport clone. I have it locked to 60hz because I’m using a Varispeed. The motor doesn’t see designed to cool at low speeds so I won’t be using variable frequency until I replace w good Baldor

Worked great for 3 months and then started arcing when plugged into the 220 outlet. It did this several times and stopped working. Junk it looks like. How about a replacement? I have an identical one on another motor that is still working. But that machine has not been used as much.

This unit was installed on my 60 year old Craftsman drill press. The drill press's spindle would never run slow enough for large drills or several other applications. I replaced the original single speed motor with a three phase motor and powered it through this VFD drive. I now have an infinite range of speeds from barely turning up to very high rpm's. Torque is surprisingly high, even at very low speeds.

After my Automation Direct VFD failed, I decided to try a Chinese brand to run my 2hp pool pump. After reading reviews and applying logic, I decided to get a 5hp VFD. I made a custom control panel with some automation for my AD unit and wanted to use it for this unit. The control is over RS485. There is no documentation on the RS485 protocol - none in the manual or on the manufacturer's website. I found a few commands on a woodworking website, enough to get me by. This unit has some nice features that the AD didn't have such as auto load detect which only delivers enough power to maintain frequency.

This is a pretty solid inverter so far for running my three-phase lathe off of single phase 240 volt. I had to get a seven and a horsepower vfd so that I could run a 3 horsepower lathe. This drive still can't start the motor at high speed without a 12 second ramp time. This manufacturer overrates their Drive by at least half to two-thirds. not a bad buy for the money, just make sure you grotesquely oversize the drive you think you're going to need for your application in order to be reliable. There's a fair amount of support for these drives on the interweb, but several of the popular CNC forums have banned their discussion as a topic, because so many people have had bad luck with them. I must have got one that was built on a Tuesday morning because this one seems to hum right along and lived a fairly long life in my welding shop. This particular device runs at Wheat State welding LLC in Derby Kansas and is installed on a three-horsepower 15x60 lathe. 6/27/23: 3 1/2 years later this drive is humming right along. I haven't had a single issue. I have a smaller one as a cnc router spindle drive that works good to. 4

I used this for my 2 kW motor on a belt sander and it works great. Relatively easy to program too. You can disconnect the face controls and use a long ribbon cable to keep the VFD in a cabinet and have the controls outside in a 3D printed housing. Still, it isn't immune to dust. Make sure to blow it out every so often with an air compressor. The first one lasted 5 years and would have lasted longer if I took care of it. I got another one and will keep it maintained.

Great product. I’m powering a 1950’s era milling machine. Wiring installation was straight forward. The factory frequency setting was way too high. I changed all the frequency settings to 60 Hz and everything is great. PD003, PD004, PD005 were the culprit. Don’t watch the video about hooking up remote switches and start making changes unless you want to have to go change them back. The instruction manual has a section on the parameter settings that is ok and was enough to figure out where the problem was.
