VFD drive for woodworking machine

[Jack]

Anyone know of a source for 1 ph to 3 ph vfd drives that are cheap. I've installed 30hp 1 ph to 3 ph Sq. D drives on machines before for friends, but I don't have the source they had. Jack

Try your local SquareD distributor again and ask to see literature on the Altivar 11 series. Reasonably priced and go from 1/4hp to 1hp. If you need a larger size the Altivar 31 goes from 1/4hp to 3 hp. If you are looking to control a larger yet size, the Altivar 71 will go up to a 7.5hp.. Also what are you trying to do with it? If you are looking to run a 3ph. motor with a

1ph drive, it maybe a waste of money. Cheap drives burn up quite easily.

Try a note up the chimney and a really big stocking.

Hey, you said _cheap_. I'm not being any less realistic than you were!

I need a drive for a 5 hp motor. The 30hp cost $2000.00 three years ago. I'll find one.

Check eBay. JP

Jack,

Try this:

didn't mention what size you need, but a 1 HP 230 volt, single phase input, three phase output drive is $125.00 (GS1-21PO).

Regards,

Rick

Jack,

Again,

GS2-25PO is 5 HP, 230 V 3ph in, 230V 3ph out ... $339.00.

Merry Christmas,

Rick

What size?

Of new equipment, AFAIK AutomationDirect (search on the web, probably

has the best deal. They have 2 or 3 lines of VFDs. The largest 1ph to 3ph converters are 3HP; above that they only have VFDs with 3 phase input.

Does anyone know of VFDs with 1ph input and 3ph output that are larger than 3HP (typically 10-11A at 220V)? I haven't done an exhaustive search, but have not found any VFDs that can be used on 1ph input larger than 3HP.

In used equipment, there are many sources. Obviously ebay. There are also several dealers that specialize in used equipment. The way I work it: Find the manufacturer that makes the equipment, then find used dealers for the equipment using google.

Good luck!

I have a Delta (VFD-B, I think) single phase input / three phase output rated for 7-1/2 HP. I use it with a 5 HP spindle on a ShopBot and have been happy with it. You can see it in the second and fourth photos on the web page at the link below (it has a beige case with black single phase cable, an orange three-phase cable, and a phone wire.) I think I have a better photo somewhere - let me know if you're interested in seeing it.

I knew that Sq. D. used to make up to 30hp in a 1ph to 3 ph vfd but I didn't know Delta drive made them that big. The Delta machines 43-255x lathe has a 2 hp Delta drive ( made by Delta drives) on it. I'll look into their line of drives. Thanks everyone, Merry Christmas.

I went digging through a pile of photos last night and found one of the Delta VFD-B - and it seems that I didn't quite have the capacity right. It's rated for 10hp rather than 7-1/2. I'll post a photo of the whole thing on abpw with a close-up of the output rating.
