Hello,
my office is relocating me from Nairobi to Santo Domingo, and I am planning to put in the container all my garage tools (I am an hobbyist, doing on my free-time mostly wood-steel forniture, but I have quite a few workshop machines). I have many single phase electric tools 230V-50Hz, and a couple of three phase equipment 400V-50Hz.
In Santo Domingo I will have a house with 3 phases, so 120/208V-60Hz, and using the voltage between two phases, I am planning to equip my garage with an surface mounted electrical system having single phase at 208V-60Hz on the new garage sockets, so to be able to run my 230-50Hz tools. Regarding my machines which use 3 phases motors I am looking for suggestions, and please let me know also if you have any observations on the single phase arrangement.
Thanks

They are incompatible, sell them and replace them after the move to ones compatible with the new address.

I did several large machines exactly like you describe. The user manual had instructions -n changing the Fuses to the proper size. The problem was, it was written in Italian. I had it translated and it worked fine.
The only thing that needed done was changing the fuse size.
Please note: these were totally mechanical machines with no logic boards not computers.

Thanks for the advise. Yes, they are 3 phases electric motors with no electronics. Do you have any references on how to change the connections and fuses? I found this post, is it correct?

OP could buy something like this... they did mention they have 3 phase and this rig is 3 phase...

60hz to 50hz

Personally, I would go this route if this could be found for under 1000$.

Changing the motors would 1000% be better in the long run though.

Sent from my new phone. Autocorrect may have changed stuff.

I would say give it a try and see,
Most of the time the motors will still work,
The slightly reduced voltage will not usually matter,
unless it is heavily loaded and borderline in HP.
the slightly higer frequency

will cause induction motorsto run slightly faster,

but again this is not usually a big problem.

YES you may have to adust your fuse sizes up a little.
If there are any problems you can use a transformer and
phase convertor.

re-sheave your motors so the equipment runs at the right speed if needed. otherwise things will move 20% faster. that could be a problem, especially if it causes things to fly apart (unlikely) or overload (more likely). very application dependent. or get a VFD and use it as a soft starter and limit it to 50Hz.
