Taken from a forum where one member is trying to sell a compressor(3 phase)


It could be changed to single fase yes but that means you have to change the motor. The question is can you get a strong enough single fase motor to work on that compressor? Any pics perhaps?

no, 3 phase motors can run on single phase, just wont be as powerful


Thats the problem. So it wont be any good running it on single phase. Best would be to change motor to single phase motor then.

no man hond you dont understand. its just going to take longer to fill the tank. its a compressor unlike a normal e/tool which you need the power to do the work

OK Whatever

on single phase that thing is going to pull lank amps and probably trip the power.

You can go to about a 3kW motor on single phase normal outlet (using the correct curve breaker) before it will trip, more on a welding outlet.

Im kinda thinking a 500l compressor will use more then a 3kw motor. D curve breaker will work you are correct.


And the prize goes to...... (from someone that builds and sell generators for a living?


Running a 3-phase motor on single phase will burn it, no matter what the scientists on this thread say.

Star-Delta starters (to lower start-up amps) start a 3-phase motor by rotating it on single phase and then switching over to 3 phase once peak RPM is reached, this allows less current draw on start-up than normal Direct-On-Line starters (DOL).

You all wanna see what happens when a star-delta malfunctions and it gets stuck in single phase? It ain't pretty.

So hou op kak praat, dit gaan nie werk nie.
