Short of transformer or new motor

[LHarrington]

Hi,
We have several Japanese manufactured lasers in our facility that when we purchased them they had shipped in dust collection units that we did not require because we have our own. They do not want them and we want to use them. Here's the question, these units are 200v 3ph units with freq drives in them and I would like to use 480v 3ph. Is there any other way to make this happen short of transforming or switch out the motor and removing the freqs?

Contact Underwriters Laboratory. They will let you know what you can and/or need to do.

Are they 50Hz motors?

Are the VFDs rated for 50Hz input?

Yes, they are 50hz and the freq drive I think is 50 hz. but there's a dial next to it to adjust up or down.

Japan is an odd country, as half of it has 50Hz mains, and the other half has 60Hz. So most Japanese kit can work on either, thus the nmanufacturer of this kit has probably fitted VFDs that work on 50Hz or 60Hz, whilst running the motors at 50Hz. So if you are lucky, you should just need to transform the voltage.

Not the drive output. The drive input: Is it 50Hz;60Hz; or 50-60 rated?
The name plate will likely tell - if not, contact the mfg.
