I'm thinking of moving some of my smaller machines to Europe. They are
currently using 220V single phase motors for 60Hz (up to 5HP) . In
Europe I have access to either 3-phase 380VAC/50Hz or single-phase
220VAC/50Hz. Can someone give me an advise? Can I use some sort of
inverter setup with a transformer, etc? Reason I'm asking is that I can
get free inverters from a friend of mine.
Depends on what you mean by "smaller".
The problem is the frequency not the voltage. A lot of smaller high RPM
equipment uses universal motors that don't care about the frequency but a
larger machine running on an induction type motor is going to run about 9%
slower and possibly heat up faster.
Many small woodworking machines use universal motors but for a small mill or
lathe running on an induction motor where you want reasonably accurate speed
you would be better off repowering it. Devices that change the frequency do
exist but one that can deliver 10 to 15 amps will cost more than 3 or 4 new
If you decide to repower do it before you ship the machines. It is fairly
easy to find NEMA motors that run on 50Hz. I am not so sure about finding
ISO motors that will fit standard NEMA mount, shaft and keyway dimensions.
