Hello there and welcome to Just Answer. My name is XXXXX XXXXX I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.
A VFD can make small voltage adjustments but to go from 380V to 230V you are going to need a small transformer.
I see you are in the US. How do you have a 380V feed?
Let me know so that we can continue.
i bought the planer here in the US and sent it to europe, the power is 380v 3phase bt i guess 220v 1phase power could come from it as well
I found a VFD with 220v 1phase input 50/60hz and 220v 3phase output, would this work fine? would the planer lose any HP power with this application? the planer is 5hp so is the VFD
If you can tell me the make and model of the VFD, I will check. Usually, you derate the VFD for single phase applications.
That was going to be a suggestion but I am not aware of one that works at 5HP.
Let me know so that I can check it for you.
it's for sale on ebay here is the link
It's a brand I have no experience with but it indicates it will run your motor with single phase in, three out.
I say go for it. The price is insanely cheap for a 5HP drive.
I'll be here if you need more help/advice/information.
great!!do you think it would work fine, with no loss of HP power? would it draw more energy? I heard running a machine at 220v 1phase would use more energy? or it would not matter since we would use a VFD? I'm just new at this.After this I guess I would be done, thanks again Steve for your time
5HP is 5HP regardless of the voltage. Energy is the same but the current will be higher on a single phase feed.
At 220V single phase the drive is going to need about 28A plus some for the drive. You should provide a 2P40A breaker with #10 wiring to the drive if it is not too long a run. Use #8 if the run is over 50'.
You can use #12 conductors on the three phase side.
I'll be here if you need more help.
No, you won't pay more. 100 watts at 12V is the same as 100 watts at 1000V. Watts is Watts and HP is HP.
Your amps will vary and therefore you may have some increased costs associated with wire size and breakers but other than that, you will have no increase in costs of actual energy used or if you do, it will be negligible.
