Question about VFD

No eBay APP ID and/or Cert ID defined in Kunena configurationI am looking for a VFD that works with linuxcnc. I have read on this forum, that the Huan Yang brand VFD works well. The question I have is can I use a 2 hp rated VFD with a 1 hp 3 phase motor? Will the following work with linuxcnc without to much issue? Thank you.

Most any VFD will work perfectly fine with Linuxcnc.

Beware of the super cheep possibly counterfeit VFDs available on ebay. They can be junk.
(The old adage "You get what you pay for" most assuredly applies.)

Hello

I have worked with installing many VFDs over the years in industrial and ship borne applications. If this the first time you have used one do your self a favor and buy recognized supported major industrial brand commonly used in your area. Be sure it comes with a manual in your native language or one you can get in person assistance with. You will have much less frustration and a working solution sooner that way. Then after you have a few under your belt use the cheap ones from unknown sources.

Hi mate,
I'm new to the forum and know very little about CNC yet, but I am very experienced with VFD's and DC drives.
If your looking for a decent VFD, look no further then Invertek, they are a British made brand, very easy to use, excellent phone support and very reasonable prices.
I have fitted 5 to a large machine in a factory (various sizes from 3 - 22kw), they run all day, every day and have been fantastic so far (2 years).

A Bit of general advice is to go for the next rating up from your motor, as it will be less prone to overload on heavy torque. Also if you are running the motor at low speeds for long periods it might be worth getting forced ventilation as the motors fan will not cool the motor enough when it's turning slowly.
Anyway if you have any problems or need help setting up your drive, I'm happy to help.
All the best,
Olly

Thx Olly! That was the information I was looking for. Ill check out Invertek. I have experience with VFD drive installation and use just not the selection for application.

The last time I bought an invertec drive, I got it online from the motor control warehouse, there prices were the cheapest I could find anywhere and saved more then 30% of our usual engineering suppliers. Out of interest are you looking for a single -> three phase drive or have you got three phase available 'on tap' ?
