Whilst I have had a little experience using 2 and 3 hp VFD's on 240 volt. I am pretty happy with how to wire them, how to dig out the star point, separate the wires, solder tails on, wire them in delta etc. My nephew wants to run a 7.5 kw 3 ph 415 volt (currently wired in star but with the connections already there to change to 240 v Delta). one can go out and spend over a $1000 on a 480volt VFD. Has anyone bought the correct VFD and are they happy with the operation of it. Are there other options like getting a cheaper 415 Volt VFD? Do they run on 2 live 240 volt wires or 3? Would it handle 480 Volt? (The 480 volt I am talking about is commonly known as single phase and was used widely in rural areas. It consists of 2 live 240 volt wires)
Can anyone suggest a way that is of reasonable cost to run this 7.5 kw 415 volt 3 ph motor on 480 volt single phase? (a VFD is highly desirable to assist with speed control)
Another simple question whilst everyone's brains are so attuned. If the voltage is right, are VFD's just as happy to run motors wound in star configuration?
Any help greatly appreciated. Thanks Ken
