Thread: VFD for Hecus 9" convertion to 240V

Hi Fernando,

your eBay link doesn't seem to work, so try this

1.5KW 2HP VFD AC Variable Frequency Speed Drive | eBay

There has been quite a bit of discussion recently on this VFD.

Fernando,

follow this link:
Help with Huanyang HY02D223B - CNCzone.com-The Largest Machinist Community on the net!

There are several pages of information and review about this Chinese VFD, along with links to download English language manuals for it.

PS: the price of AU$ 100 is very good. However, keep in mind the 2 year warranty may not be of much value to you in Australia, if you have to factor-in postage and handling and wait time back and from the USA. Also, be aware this is a simple V/Hz technology drive, meaning it will not have not have much torque at frquencies below 25Hz (the useful speed range with a lathe is only about 4:1). Newer technology drives with "sensorless vector" technology have a speed range of up 8:1 and would be better suited for a lathe spindle - but of course would cost more.

hi mate that seems real cheap.. i wonder if the motor data plat info is all you need as far as set up goes

Just so we have the Huanyang Users' Manual link on this forum as well (since I put it up in the ofrst place on the CNC forum):

thanks guys for the info, I know is not the best drive out there, but for the price i think is worth it, I will get some speed control ( ill need to change pulley every now and then, but i don't mind) but the main thing is that I can run the 3phace motor from my 240v single phase supply with a ramp up speed.
I already pay for one Ill let you guys know how it goes.
Cheers

Fernando

The VFD you are looking at is the wrong size for your motor. Both should be the same size as each other. This is an area where bigger isn't better. While it will "probably" work ok, I very much doubt the manufacturer will support such a combination.
