Huanyang VFD,Variable Frequency Drive,AC Single Phase 110/120V Input, for Three-Phase 110V Motor/Spindle Speed Rotation,HY Series (3kW 4HP)

I really wanted a cheaper alternative to the more expensive units. I purchased the 110v/3hp, running a 3 phase 2.2kw 2.01 hp motor with 110v input from a standard wall plug. I took a chance on this due to some good reviews. I installed the VFD on a small lathe and I have to say that it performs very well. The manual should be rewritten by a technical writer because if someone doesn’t have any experience with VFD’s it could be challenging to setup. In this case it was a fairly simple project and the Huanyang VFD was a great alternative. The one thing that really took me by surprise is the responsiveness of their technical support and shipping time. Tech support answered questions within a few hours and shipping was 5 days! I can’t get service like that from the joint down the road that gouges me every time I walk in the door or call. Since it’s been installed I’ve really run it hard. So far so good! I’m happy all around with this unit and will be buying more.

Easy to program

So far, so good. I have it powering a 110v 60Hz water pump for a pond. Wiring was straight forward and I have dialed down the frequency to 49Hz. I have it connected to a Shelly relay for on/off control, but I have not figured out the PD setting to have it auto restart the motor after a power cycle...waiting on a response from customer service.Not a huge deal for my use case, but I have not figured out what the knob does. I have another VFD with a knob that functions as expected, but I'm currently just using the arrow buttons on this one. I either have a faulty knob, don't have settings correct, or I am not using functionality the knob is built for...

I purchased this to use on a drill press, connected to a 3 phase motor. Works great, the instructions are a little hard to follow, but you can figure it out.

Very nice VFD controller, the number of parameters available for tuning is impressive and a bit imposing. I particularly enjoy being able to set precise values for maximum voltage and current, as well as the amount of time it will spend increasing the speed until it reaches the target RPM value. The latter means you can drive very heavy motors/devices that would otherwise instantly overload the controller, as well as preventing the motor from accelerating too quickly while adjusting the speed via the front control knob.It would be nice to have a more detailed display since it only shows a single value at one time (Defaults to the RPM), having voltage and current consumption would be very useful.FYI the application I'm using this controller for is to drive a 24V turbomolecular pump. The blade assembly is very heavy and without a very slow acceleration it trips the current limiting, so with the right parameters set it works very well with this controller.

ZERO STARS. It blew after 6 weeks of extremely light use. Return window closed and no way to contact seller. DO NOT BUY!!!

A bit of a learning curve to wire to your specific CNC machine but the is jacket of info on the internet to find what you need. Easy to program. I’ll end up buying at least one more when I add variable speed to my lathe.

Powerful as expected.
