Buck Boost Transformer 380V 240V 3Phase

[Luke Barber]

I have a machine that I built for the US. It has a couple of Lenze servomotors [URL unfurl="true"]https://files.clrwtr.com/userfiles/ct/documents/lenze/lenze-mcs-synchronous-servo-motors.pdf[/url] and Lenze VFD 240V three phase. [URL unfurl="true"]https://files.clrwtr.com/userfiles/ct/documents/lenze/lenze-smvector-washdown-duty.pdf[/url]

I have to build another machine for China.

I want to keep all of the same components, and build it for the 240 Volt three phase. But it won't

work over there. I will need to get them to get a 3 phase 380V to 240 V Buck Boost transformer.

Any suggestions on where to get one?

Also, they use 50hz, not 60hz. Could transformer heating be an issue?

Thank you in advance for any guidance.

One link does not list motor voltage.
The other link does not list frequency.
You may be able to use a 480 Volt VFD on 380 Volts 50 Hertz.
It depends.
A 60 Hz transformer for use on 50 Hz must be rated for 120% of the applied 50 Hz voltage.

You do not need a transformer, you just need a 380V rated drive. You can tell the drive to not deliver more than 240V to the motors, that's just a programming function. You just need a VFD that will accept 380V input. Most 480V rated drives will do that, but you need to double check.
