Inverters

3 phase inverters. Who is the best to buy from & what make least trouble

 

[daleyd]

Do you mean inverter welder or inverter as in variable speed drive type?

 

[500e]

Single phase to 3 phase

 

[rikrobson]

What do you want to run 3 phase?

I've got an Allen Bradley Powerflex and an SEW euro drive driving bits and bobs........... Pretty straightforward to set up and use even for a spanner monkey like me. Plenty kicking about on the bay

I have a cheap Chinese 3 Kw/4 HP one that cost less than £100 and it works faultlessly powering my mill, lathe, drill and various other bits of kit. Runs from a 13 amp plug.
The only thing that lets it down is the Chinglish manual supplied with it but there are better translations available on the net.
It gets used weekly and has done for a couple of years now.

Plus one on this. I run three of these on my CNC router, lathe and mill and have never had problems.

There must be some Chinese ones to steer clear off

Thanks WS

Hmmmm could you run a 3 phase tig welder off that?
Or use it to control a single phase lathe motor form a single phase supply?.

Generally you wouldn't run a 3 phase welder as they would require 440v 3 phase and these kick out 230v 3 phase, but you can run a suitable 3 phase motor providing it is 230v compatible.

My lathe has a Mitsubishi VFD with a Newton Tesla controller, it works very well. It was bought, fitted, set up, etc by brewdexta,he knows more about it than me.

may i ask if you used default factory settings or did you program this drive your self?

 

[MattH]

You have to program them to suit your motor and application.
It's not that difficult though.

 

[winchman]

I have used these several times and found them to be excellent

Hmm, title says 240v input but text in the ad says 380v input contact us for item stock on 240v input. I'd check with them before buying just in case.

I defaulted the inverter first and changed around 3 settings I think, number of poles, size in KW and maximum speed. Really easy to do.

I think that's a error in copying the wrong Detail Parameter into the add as the rest of the add, including the title, states 220v plus the 380v inverters are more expensive.

 

[Wendelspanswick]

Just to add that the inverter I have will refuse to run if the data programmed into it does not match the attached motor.
I did try and upload the manual but there is a 5MB limit and the .PDF is 10MB.
