I'm looking to buy a bandsaw that has a 1hp 230 volt 3 phase motor that I would need to run off of 240 single phase. Has anyone bought the inexpensive VFD off of Amazon/ Ebay or suggestions on better quality VFD's?

There is a thread (sticky)dedicated to this subject in the "General tool discussion"
General too discussion : VFD's link
read what some of the other experiences have been. It seems the "Teco" brand is priced well, popular and favored for ease of set up and general use.

You will do fine with a Teco VFD but beware of cheap eBay & Amazon no name or support drives.

YT House Work has some videos on cheaper VFDs for 2x72 knife grinder kits:

I have a Teco 120v input 240v 3 phase output for my Clausing drill press 1hp.

Only problem is VFD's do not play well with GFCI's, which are required for 15 & 20A 120V receptacles, in shops, garages, outbuildings.

A Teco L510 series vfd is what I have been using. A 1 hp model with 240 single phase input is about $145 from Dealers Electric. I have two years on both of mine, one on the lathe and one on the mill.

What's so bad about his wiring? Definitely seen worse :lol:

I see nothing good about his methods, & buying insulated crimp connectors & removing the insulated sleeve seems rather foolish, since uninsulated ones are available. Another case study why people who think 110 & 220V still exist as nominal voltages should not do electrical work just based on piss poor workmanship.

The rest of the sander makes me want one.

I've had a Teco 240v single to 3 phase on my mill for about 15 years and another on my South Bend lathe for about 10 years in a home shop environment. I had a rotary single to 3 phase before and hated it. I have been so happy with the Teco's and the ability to change rpm by turning the knob is another huge benefit.

I like the invertek IP66 drives. no enclosure needed (just wire your whips to the built-in junction box), and glove friendly controls on the front:

And demonstrates absolutely ****** wiring methods. His sander is cool, the electrical not so much.

Did you post your comments to his YT channel? I'd like to see how he responds.

Some YTers don't like any comments that are negative in any way towards them or criticize their methods (e.g. Ask Tractor Mike, outdoor with the morons etc.). You can tell a lot about a so-called "expert" on how they handle criticism.

While I generally think the wiring police over do things, I do think that this guy could have done a bit better, especially with the cord entering the motor housing. As for the crimps, I have removed the insulation many times because there were no uninsulated crimps available when I needed them. I have also had to modify the terminal end on more than one occasion. You have to admit he tried, I wouldn't have even used terminals in the plug, just the wire.

YT = Google so rarely go there much less register. :)

His work is absolute ****, while nobody does perfect work he could at least try, I might not complain if he had made a disclaimer that was done just for testing and should not be left that way.

Another happy TECO drive user here. 120v to 240v 3ph driving a 1 HP metal working lathe motor.

This is very true. In my basement, I have a circuit in the ceiling that is not GFCI, and I have to use that for the VFD.

If you already have a 240v 1ph circuit, I'd go with the 240v to 240v 3ph version.

The 2020 NEC will require them on 240V.

Should have mentioned it was another of his videos, my fault.

grinded the plating off of the terminal connectors smh

shouldve soldered the connectors as his crimping was not that good
