Sorry I don't understand what do you mean and if is some joke in relation to what happened to the vfd just to let you know anything in relation to the electronic sounds like Chinese to me so can you explain yourself better please?

just to let you know anything in relation to the electronic sounds like Chinese to me so can you explain yourself better please?
that means im not very good with electronic im more mechanical minded type,i will upload a youtube video with the test doh.what happened in that video happened also in my garage with mobile phone and pc,you won't understand the language on the ideo so please follow the multimeter and the pc screen to see what im talking about
Cén fáth go mbeadh sé tábhachtach an dtuigeann WE an Ghaeilge Gaibh chomh fada agus gurb é TÚ an ceann nach dtuigeann leictreachas srutha ailtéarnach bunúsach?
By the way thermite, I'm not Irish you should have had understood the language on the video no? You know everything and you are above the common human am I right? Anyway you've been great using Google translate,I'm sure you're the best using it
Why would ANYONE have bothered to watch the video?
You put a meter on an Alternating Current source and "discovered" that it ... ta da .. does exactly what it says it does.
A VFD generates fast-rise switching transients. Those radiate. Sensitive devices detect that.
Nature of the physics as well. That, too, was well-known before you made the video.
So where do DIY "videos" enter the human experience?
Looks like a "force multiplier" for the rapid propagation of abysmal ignorance to me.
In ANY language.
So they were too polite to say it:Because beside you the rest of the group here never showed up arrogance,
thanks for the lesson prof!
I have to agree with you unfortunately for me,probably I should have done few research first,I don't have the manual with the vfd and I thought the easiest way to understand what was going on was to simply ask to others with more knowledge and experience than me in that field,without people making questions this forum wouldn't have reasons to exist in first place,there is way and way to say things especially to a person that you don't know, people here is willing to help no matter how,because anyone at some stage of his life is been where I am now,no one is born knowing everything,if I'm not willing to help or I believe that a stupid question was made I don't go around the forum offending people freely for no reason,I don't disrespect someone only because he doesn't know something,i just wouldn't get involved in the conversation in first place,keep in mind this,if only half of the people on this forum would act as the genius who replied to me rest assured that this website would be closed within a couple of months because nobody's looking for information or for help would be willing even to consider the access to this forum,every day In my job I have to deal with people who doesn't have knowledge of thermodynamics or fluid dynamics and so on but I do my best in simple words trying to explain them the difference between a product rather than the other,but this is just matter of good manners and respect for the next,where I grow up if you're parents doesn't teach you how to respect the people rest assured that someone else does that but you'll learn in the hard way,in the case of this person it's clear that he never had that type of education and he feel protected because behind is PC but guess what? Not always is trueThere is an expectation that a certain amount of preparatory investigation will have been done prior to posting "I need Help" topics in Practical Machinist.
Pleading "I don't know anything about anything" is not going to get much sympathy.
The internet is a thing, But it is not an excuse.
I want to thank you all,you have no idea how much i appreciate your help! I am a completely dumb when its about electric or electronic systems im good with mechanical stuff but not the electronic so just to better understand,that transformer doesnt allows me to switch the motor from 380 to 220 right?
so in detail what exactly does on the lathe? You are right on that one That transformer is just to power the coils of the relays
You do not need them relais and that transformer any more All the switching can be done on the VFD
second: if i find that im lucky enough to have the second type of motor like peter said i can change the wiring and using as 220 trifase and from there using a vfd to transform the trifase to a single phase for my 220 correct? You swap the motor to a input of 3phase 220volts instead of 380volts That is what you can do with a dual voltage motor No need for a transformer Then your VDF will change the single phase 220volts input to 3ph 220volts output That matches the motors need Then with the VFD you can change the frequency and therefore the speed
assuming that i can do this then i dont need anymore all the original switches,relay etc because i can control everything from the vfd panel am i right? Yes Perhaps you need a potmeter and or stop start pushbuttons depending the VFD and your needs tomorrow i will post more pictures of the motor and maybe one of you can help me to figure out what type of motor it is and whats the best way to proceed in order to use my lathe on a 220v circuit..many many thanks guys
